Background

With the rapid development of internet technology, users increasingly utilize networks to complete various activities, such as office work, entertainment, shopping, financing, and the like. Users typically obtain these services from multiple service providers, and the users register with the servers of the respective service providers, and each time they obtain a service, they need to provide an account number and a password to the servers, so that the servers authenticate the users and provide the corresponding services.

For security reasons, users should try to avoid using the same account number and password at multiple service providers. As the number of services that users wish to obtain increases, remembering the account number and corresponding password at each service provider becomes an increasingly heavy burden for users. Meanwhile, as network services increasingly spread to the aspects of life, users always need to input accounts and passwords to complete authentication, operation is complex, and efficiency of obtaining network services is reduced.

Detailed Description

Wearable devices are portable devices that can be worn on the body by a user, or integrated into a user's clothing or accessories, such as bracelets, smart watches, smart sports shoes, smart clothing, smart glasses, smart helmets, smart rings, and the like. The wearable device has partial calculation function, can be connected to terminals such as smart phones, tablet computers and personal computers through hardware interfaces or wireless local area networks, and realizes various functions through data exchange with the terminals.

Wearable devices are usually dedicated to a user, and some wearable devices are worn on the user at any time and any place, and to a certain extent, such wearable devices represent the user. The embodiment of the application provides a method for authenticating a user, which authenticates the user by using the storage and calculation functions of wearable equipment, and does not need the user to memorize and frequently input an account number and a password, so that the problems in the prior art are solved.

A network environment applied in the embodiment of the present application is as shown in fig. 1, where the wearable device is accessed to the terminal through a hardware interface or a Wireless local area network, the hardware interface may be an audio interface, a USB (universal serial Bus) interface, and the like, the Wireless local area network may be a Bluetooth (Bluetooth), a Wi-Fi (Wireless-Fidelity), a ZigBee (ZigBee protocol), and the like, and the terminal may be a smart phone, a tablet computer, a personal computer, and the like. The terminal communicates with the server via a communication network, such as the internet and/or a mobile communication network, on which the user sends access to the server, which authenticates the user. In the embodiment of the application, the type of the terminal, the hardware interface or the wireless local area network protocol of the wearable device access terminal, the protocol and the networking structure of the communication network, and the specific implementation mode of the server are not limited.

In one embodiment of the present application, the flow of the method for authenticating a user on a server is shown in fig. 2, and the flow on a terminal is shown in fig. 3.

In this embodiment, the server stores the corresponding relationship between the user identifier of the user, the wearable device identifier, and the server authentication key. The user identifier is a unique identity which is different from other users for a certain user to the server, such as a user name, a registered mailbox and the like; if the user is bound to the Mobile terminal, the user may also be a number, an IMEI (International Mobile equipment identity), and the like of the bound Mobile terminal. The wearable device identifier is used to uniquely represent the wearable device, and may be a hardware address of the wearable device, such as a Media Access Control (MAC) address, depending on the specific device type and the wireless local area network protocol used. The server authentication key is stored on the server, and is identical to or corresponds to the device authentication key stored on the wearable device, according to an encryption algorithm using the server authentication key. The wearable device identification and the server authentication key stored on the server correspond to each other, and if a user can have more than one wearable device for authentication, one user identification may correspond to two or more wearable device identifications and server authentication keys. It should be noted that the corresponding relationship between the user identifier, the wearable device identifier, and the server authentication key may be stored locally in the server, or may be stored in another storage device accessible by the server, such as a disk array of a storage area network or a cloud storage network, which is not limited in this embodiment.

On the terminal, step 310, an authentication request is sent to the server according to the operation of the user, where the authentication request carries the user identifier and/or the wearable device identifier of the user.

At the server, an authentication request sent by the user through the terminal is received, step 210.

When a user requests a service (such as login, personal account access, payment and the like) needing identity authentication from a server on a terminal, the server requests related information needed by the user to the terminal. The terminal sends an authentication request to the server, and the authentication request carries the user identification of the user, or the wearable device identification of the user, or the user identification and the wearable device identification of the user.

After the server receives the authentication request of the terminal, the server can determine which user requests authentication through the user identification and/or the wearable device identification in the authentication request.

On the server, step 220, downlink authentication information is acquired, and a detection instruction carrying the downlink authentication information and the wearable device identifier of the user is issued to the terminal.

The downlink authentication information may be a piece of authentication data, or may be a ciphertext obtained by encrypting the authentication data using a server authentication key stored in the server. The server may obtain the authentication data in any manner, such as randomly generating, or intercepting a certain number of bytes from a certain file or picture; the server can generate authentication data locally and can also obtain the authentication data from other servers; this embodiment is not limited to this.

After receiving an authentication request of a terminal, a server extracts a user identifier and/or a wearable device identifier in the authentication request, searches whether the identifier is included in a corresponding relation among the stored user identifier, the wearable device identifier and a server authentication key, and rejects the authentication request of the terminal if the identifier is not included or the user identifier and the wearable device identifier in the authentication request do not belong to the same user; otherwise, the server acquires authentication data, and for downlink authentication information of a plaintext, the server encapsulates the authentication data and the wearable equipment identifier of the user in a detection instruction and sends the detection instruction to the terminal; and for the downlink authentication information of the ciphertext, the server encrypts authentication data by using a server authentication key corresponding to the user identifier or the wearable device identifier in the authentication request to generate downlink authentication information, encapsulates the downlink authentication information and the wearable device identifier of the user in a detection instruction, and issues the downlink authentication information and the wearable device identifier of the user to the terminal.

On the terminal, step 320, a detection instruction of the server is received, where the detection instruction carries downlink authentication information and a wearable device identifier.

On the terminal, step 330, sending the downlink authentication information to the wearable device specified in the detection instruction, and receiving the uplink authentication information returned by the wearable device; and the uplink authentication information is generated by the wearable device according to the stored device authentication key and the downlink authentication information.

The terminal receives the detection instruction of the server, extracts the wearable equipment identification and the downlink authentication information from the detection instruction, and sends the downlink authentication information to the wearable equipment (namely, the wearable equipment with the wearable equipment identification in the detection instruction) specified in the detection instruction. If the wearable device specified in the detection instruction has not been accessed to the terminal, the terminal needs to complete the connection with the wearable device according to the wireless local area network protocol supported by the wearable device.

As described above, the wearable device designated by the server stores the device authentication key that is the same as or corresponds to the server authentication key. After the wearable device receives the downlink authentication information, encrypting the downlink authentication information of the plaintext by using the device authentication key by the wearable device to generate uplink authentication information of a ciphertext; and for the downlink authentication information of the ciphertext, the wearable equipment decrypts the downlink authentication information by using the equipment authentication key to generate the uplink authentication information of the plaintext. The plaintext downstream authentication information corresponds to the ciphertext upstream authentication information, and the ciphertext downstream authentication information corresponds to the plaintext upstream authentication information. And the wearable equipment returns the uplink authentication information to the terminal.

On the terminal, step 340, sending a detection response carrying the uplink authentication information to the server.

And after receiving the uplink authentication information returned by the wearable equipment, the terminal encapsulates the uplink authentication information in a detection response and sends the detection response to the server. The detection response usually also carries the wearable device identifier.

On the server, step 230, a detection response carrying the uplink authentication information returned by the terminal is received.

On the server, step 240, the server authentication key of the user is used to match the downlink authentication information and the uplink authentication information, and if the matching is successful, the user passes the authentication.

And the server receives the detection response returned by the terminal, extracts the uplink authentication information from the detection response, and judges whether the uplink authentication information is matched with the downlink authentication information by using the server authentication key of the user so as to determine the authentication result of the user. Specifically, for the uplink authentication information of the plaintext, the uplink authentication information may be compared with authentication data used to generate a ciphertext, or the uplink authentication information is encrypted by a server authentication key and then compared with the downlink authentication information, if the uplink authentication information is the same as the downlink authentication information, the user passes the authentication, otherwise, the authentication fails; and comparing the decrypted uplink authentication information of the ciphertext with the downlink authentication information by using a server authentication key, if the decrypted uplink authentication information is the same as the downlink authentication information, the user passes the authentication, and otherwise, the authentication fails.

And the server returns the authentication result of whether the user passes the authentication to the terminal.

On the terminal, step 350, receiving a user authentication result determined by the server according to the uplink authentication information, the downlink authentication information and the server authentication key.

In the embodiment, the same or corresponding server authentication key and device authentication key are arranged on the server and the wearable device, the server authenticates the designated wearable device by using the device authentication key stored on the wearable device and the server authentication key stored on the server through interaction with the terminal, so that authentication of a user corresponding to the wearable device is completed, the user does not need to remember an account number and a password, and input the account number and the password in the authentication process, the burden of the user is reduced, and the efficiency of the user for acquiring network service is improved.

In one implementation, a user public key of a user may be stored in a server, a user private key of the user may be stored in a terminal, different user identifications use different user public keys and different user private keys, and the user public key and the user private key are a pair of keys in asymmetric encryption. The user public key stored on the server corresponds to the user identification, the wearable device identification and the server authentication key of the user. In this implementation manner, the terminal signs data (including uplink authentication information, and may also include other data such as wearable device identifier, user identifier, and the like) carried in the detection response with the stored user private key, and sends the signed detection response to the server; the server uses the user public key of the user to perform signature verification on the detection response, if the detection response passes the verification, step 240 is executed to perform matching of the uplink authentication information and the downlink authentication information, and if the detection response fails the signature verification, the server notifies the terminal that the authentication fails. This implementation requires that a terminal accessed by a user performs authentication using a wearable device should store the user private key of the user, which can achieve better security.

In addition, the terminal identifier may be added to a correspondence relationship between the user identifier of the user, the wearable device identifier, and the server authentication key stored in the server, so as to restrict the terminal that can perform user authentication through the accessed wearable device. In this case, the server stores the corresponding relationship between the user identifier of the user, the wearable device identifier, the server authentication key and the terminal identifier; the terminal carries the terminal identification of the terminal in the authentication request sent to the server; after receiving the authentication request, the server searches the stored corresponding relationship for the terminal identifier corresponding to the user identifier or the wearable device identifier in the authentication request, compares the terminal identifier with the terminal identifier sending the authentication request, if the terminal identifier is the same as the user identifier or the wearable device identifier in the authentication request, the step 220 is executed to continue the authentication process, and if the terminal identifier is different from the terminal identifier in the authentication request, the authentication request of the terminal is rejected, and the user authentication fails. This implementation amounts to binding the wearable device and the terminal that can authenticate the user through the wearable device; since the terminal (especially the mobile terminal) is usually also dedicated to one user, binding the wearable device and the terminal can greatly increase the security of user authentication.

The authentication process in this embodiment is applicable to any scenario where the user identity needs to be authenticated, such as user identity authentication during login, identity authentication when the user accesses a personal account, identity authentication when the user pays through a third-party payment platform, and the like. After the user passes the authentication, the server can provide subsequent services in the scene, and the terminal executes subsequent operations in the scene, for example, when the terminal is used for identity authentication in a payment scene, the authentication request sent by the terminal to the payment server is a payment request; after the user is authenticated, the payment server may provide a payment service to the authenticated user; and after receiving the authentication result that the server user passes the authentication, the terminal can cooperate with the payment server to complete the payment operation of the user.

In this embodiment, the correspondence between the user identifier of the user, the wearable device identifier, and the server authentication key may be preset on the server, and the corresponding device authentication key may be preset on the wearable device; before the authentication process, the correspondence relationship may be generated on a server through a registration process, and a device authentication key may be written in the wearable device.

Another embodiment of the present application provides a method for registering a wearable device, where the flow of the method on a server is shown in fig. 4, and the flow on a terminal is shown in fig. 5.

On the terminal, step 510, a wearable device registration request is sent to a server according to a user operation.

On the server, step 410, a wearable device registration request sent by a user through a terminal is received.

The user registers the wearable device on the terminal to the server, the terminal sends a wearable device registration request to the server according to the operation of the user, and the registration request comprises the user identification and the wearable device identification of the user.

On the server, step 420, a server authentication key and an equipment authentication key of the user are obtained, and a write-in instruction carrying the equipment authentication key and the wearable equipment identifier of the user is issued to the terminal.

After receiving a wearable device registration request of a terminal, according to an encryption algorithm adopted by uplink authentication information or downlink authentication information in an authentication process, a server acquires a server authentication key and a device authentication key which are used for the encryption algorithm and correspond to a wearable device identifier. The server authentication key and the device authentication key may be one key (e.g., a key of a symmetric encryption algorithm) or may be a pair of keys (e.g., a public key and a private key of an asymmetric encryption algorithm). The server may generate itself or may obtain the server authentication key and the device authentication key from other servers.

And the server encapsulates the acquired equipment authentication key and the corresponding wearable equipment identification in a write-in instruction and sends the write-in instruction to the terminal.

On the terminal, step 520, a write instruction of the server is received, where the write instruction carries the device authentication key and the wearable device identifier of the user.

On the terminal, step 530, the operation of writing the device authentication key is performed on the wearable device specified in the write instruction.

And after the terminal receives the write-in instruction of the server, the terminal sends the equipment authentication key in the write-in instruction to the wearable equipment and requests the wearable equipment to store the equipment authentication key. According to the difference of the wearable device and the difference of the set authority, the wearable device may need the user to confirm the write operation before completing the storage of the device authentication key. For example, with a hand ring, the user typically needs to tap to confirm.

On the terminal, step 540, a write response is sent to the server, and the write response carries a message indicating whether the write device authentication key is successful. And after the terminal finishes the writing operation with the wearable device, packaging the message of whether the writing is successful in the writing response, and sending the message to the server.

On the server, step 430, receiving a write-in response returned by the terminal, and if the write-in response indicates that the device authentication key has been successfully stored in the wearable device specified in the write-in instruction, storing a correspondence between the user identifier of the user, the wearable device identifier, and the server authentication key, and the wearable device being successfully registered; and if the message carried in the write response is that the equipment authentication key is not successfully written, the registration process fails. And the server sends the registration result to the terminal.

The server may require the terminal to provide the user's password to increase the security of wearable device registration. Specifically, the server receives a write-in response of the terminal, and if the message carried in the write-in response is that the equipment authentication key is successfully stored in the wearable equipment, a password confirmation request is issued to the terminal to request the terminal to provide a password of the user identifier corresponding to the wearable equipment identifier; the terminal receives the password confirmation request of the server, and returns the user password input by the user to the server by carrying the user password in the password confirmation response; receiving a password confirmation response carrying a user password by the terminal on the server, if the user password is correct, storing the corresponding relation of the user identification of the user, the wearable equipment identification and the server authentication key, and successfully registering the wearable equipment; and if the user password is wrong, rejecting the registration request of the terminal, and failing to register. And the server sends the registration result to the terminal.

In one implementation, the user public key and the user private key of the user may be automatically generated during the registration process. Specifically, after the operation that the terminal writes the device authentication key into the wearable device is successful, the terminal generates a user private key and a user public key of the user according to a certain algorithm, locally stores the generated user private key, encapsulates the user public key in a write-in response, and sends the write-in response to the server; and after the terminal successfully writes the equipment authentication key into the wearable equipment or verifies that the user password is correct, the server stores the corresponding relation among the user identifier of the user, the wearable equipment identifier, the server authentication key and the user public key.

In some application scenarios, a server public key and a server private key are preset on a server, and a terminal private key and a terminal public key are preset on a terminal, wherein the server public key and the terminal private key are a pair of keys, and the server private key and the terminal public key are a pair of keys. In these scenarios, the server in the authentication method embodiment may sign the detection instruction with the stored server private key, and send the signed detection instruction to the terminal; and the terminal performs signature verification on the received detection instruction by using the stored terminal public key, and if the verification fails, the detection instruction is rejected, and the authentication fails. In the embodiment of the registration method, the server can sign the write-in command by using a stored server private key and send the signed write-in command to the terminal; and the terminal performs signature verification on the received write-in command by using the stored terminal public key, and if the verification fails, the write-in command is rejected, and the registration fails. The terminal can sign the write-in response by using the stored terminal private key and send the signed write-in response to the server; and the server performs signature verification on the received write response by using the stored server public key, and rejects the registration request of the terminal if the verification fails.

The server and the terminal can communicate through an encrypted channel to further improve the security of wearable device registration and user authentication. For example, the detection command and the detection response in the authentication method embodiment, and the write command and the write response in the registration method embodiment may be transmitted in an encrypted channel. For the implementation of the encryption channel and the encryption method adopted, please refer to the prior art, and further description is omitted.

the wearable device receives payment authentication information sent by a payment client, and extracts downlink authentication information issued by a server based on a payment request of a user sent by the payment client from the payment authentication information; generating uplink authentication information according to the stored equipment authentication key and the downlink authentication information, and sending the uplink authentication information to the payment client;

the payment client receives uplink authentication information returned by the wearable device and sends the uplink authentication information to the server in authentication response information;

the server receives authentication response information which is returned by the payment client and carries uplink authentication information, a server authentication key of the user is used for matching the downlink authentication information and the uplink authentication information, if the matching is successful, the user passes the authentication, and payment operation is carried out after the authentication is passed; the server authentication key of the user is the same as or corresponds to the device authentication key of the wearable device specified in the authentication instruction.

In the embodiment, the same or corresponding server authentication key and device authentication key are arranged on the server and the wearable device, and the wearable device is authenticated by using the device authentication key and the server authentication key, so that the payment authentication of the user corresponding to the wearable device is completed, the user can pay by using the wearable device on the payment client, the account and the password do not need to be memorized, the account and the password do not need to be input in the authentication process, the burden of the user is reduced, and the payment efficiency is improved.

In an application example of the application, after a user registers a bracelet in a payment server through a client App (application program) running on a mobile phone terminal, network payment can be completed through the bracelet without inputting an account number and a password. Paired server public keys and terminal private keys, and paired server private keys and terminal public keys are preset on the payment server and the client App. The payment server can run a server of a server program corresponding to the client App, and can also be a server of a third-party payment platform supporting the client App. The specific process is as follows:

the user sends a wearable device registration request to a payment server through a client App (application program) running on a mobile phone terminal, applies for opening bracelet payment, and uploads a user identifier (an account number of the user in the payment server), a mobile phone terminal identifier (IMEI) and a bracelet identifier (a bracelet MAC address) to the server in the registration request.

The payment server generates a symmetric key (namely the same server authentication key and equipment authentication key) for authenticating the bracelet through a preset algorithm, signs the symmetric key, the user identifier and the bracelet identifier through a preset server private key, encapsulates the signed symmetric key, the user identifier and the bracelet identifier in a write-in instruction, and sends the signed symmetric key, the user identifier and the bracelet identifier to the client through an encryption channel between the payment server and the client.

After receiving the write-in command of the server, the client firstly verifies the legality of the data in the write-in command according to a preset terminal public key, and directly refuses the write-in command if the data is not legal. After passing the validity verification, the client connects with the designated bracelet in the write-in instruction, and writes the symmetric key issued by the payment server into the bracelet after the connection is successful. The user need strike the bracelet and come to confirm writing operation in the in-process that the symmetric key wrote into the bracelet, and after the user struck the bracelet, the symmetric key wrote into the memory area of bracelet.

And after the write-in operation is successful, the client generates a pair of asymmetric keys, namely a user public key and a user private key corresponding to the user identifier according to the user identifier. And the client signs the result of whether the write-in operation is successful, the bracelet identification and the generated user public key through a preset terminal private key, encapsulates the signed information in a write-in response, and sends the write-in response to the payment server through an encryption channel. The user private key is stored locally by the client.

After receiving the write-in response of the client, the payment server verifies the signature of the client through a preset server public key, and rejects the registration request of the client if the verification fails. And after the signature verification is passed, the payment server issues a password confirmation request to the client, and the client is required to provide the password of the account of the user on the payment server.

The client displays prompt information for inputting the password to the user, and the user inputs the password of the account number of the user on the payment server at the client. The client sends the received password to the payment server in a password confirmation response.

And the payment server checks the user password in the password confirmation response, stores the corresponding relation of the symmetric key (server authentication key), the user identifier, the mobile phone terminal identifier, the bracelet identifier and the user public key generated by the client after the verification is passed, informs the client that the bracelet is successfully registered, and finishes the registration process.

After the bracelet is successfully registered on the payment server, when a user wants to pay through the bracelet, an authentication request of payment is sent to the server through the client, wherein the authentication request comprises order information to be paid, a user identifier, a mobile phone terminal identifier and the bracelet identifier.

After receiving an authentication request of the client, the payment server compares the mobile phone terminal identification in the authentication request with the mobile phone terminal identification corresponding to the bracelet identification in the authentication request in the stored corresponding relation, if the mobile phone terminal identification is different from the bracelet identification in the authentication request, the authentication request is rejected, and the payment fails; and if the authentication information is the same, the payment server generates random plaintext data, and the plaintext data is used as downlink authentication information. And the payment server signs the downlink authentication information, the user identification and the bracelet identification by using a preset server private key, encapsulates the signed downlink authentication information, the user identification and the bracelet identification in a detection instruction, and sends the signed downlink authentication information, the user identification and the bracelet identification to the client through an encryption channel between the payment server and the client.

After receiving the detection instruction of the payment server, the client firstly verifies the validity of the signature data in the detection instruction according to a preset terminal public key, and if the data is not legal, the detection instruction is rejected, and the payment fails. After the validity of the signature is verified, the client is connected with the designated bracelet in the detection instruction, and the downlink authentication information in the detection instruction is sent to the bracelet after the connection is successful. The bracelet encrypts the downlink authentication information by using the stored symmetric key to generate uplink authentication information and returns the uplink authentication information to the client. The process that the bracelet encrypts the downlink authentication information does not need knocking confirmation of the user, so that the user operation can be further reduced, and the user experience is optimized.

After receiving the uplink authentication information generated by the bracelet, the client signs the uplink authentication information by using a locally stored user private key, encapsulates the signed data and the bracelet identification in a detection response, and sends the detection response to the payment server through an encryption channel between the client and the payment server.

And after receiving the detection response uploaded by the client, the payment server performs signature verification on the detection response according to the user public key corresponding to the bracelet identification in the detection response, and if the signature verification fails, the authentication request fails. After the signature verification is successful, the payment server encrypts downlink authentication information by using a symmetric key corresponding to the bracelet identification, and compares the encrypted data with the uplink authentication information in the detection response, namely, whether the downlink authentication information encrypted by the payment server is the same as the downlink authentication information encrypted by the bracelet is compared, and if the downlink authentication information encrypted by the payment server is the same as the uplink authentication information encrypted by the bracelet, a message of successful authentication is returned to the client and the payment of the order is continued; if not, returning a message of authentication failure to the client. After receiving the message of successful authentication, the client and the payment server complete the payment operation of the user order; and if the client receives the authentication failure message, informing the user that the payment can not be finished due to the authentication failure.
