If the authorized data is encrypted by using the agreed key in the process of sending the verification data by the electronic door lock, the unlocking equipment can firstly decrypt the encrypted authorized data by using the agreed key to obtain the authorized data after receiving the encrypted authorized data sent by the electronic door lock. The unlocking device receives the authorization data and then generates authorization response data according to the authorization data, and when the authorization response data are specifically generated, the unlocking device can encrypt the authorization data by using a private key of the unlocking device, namely, the authorization data are signed and generated.
After the unlocking device generates the authorization response data, the signed signature data and the digital certificate can be sent to the electronic door lock together, wherein the digital certificate comprises the public key and the digital signature of the unlocking device.
S203, the electronic door lock receives the authorization response data fed back by the unlocking equipment and the digital certificate of the unlocking equipment, verifies the digital certificate and the authorization response data, and marks the unlocking equipment as a hardware key after the verification is successful.
Specifically, the electronic door lock can adopt the public key of the root device to decrypt the digital certificate to verify the digital certificate, and the public key of the unlocking device can be obtained after the verification is passed; and then, the public key of the unlocking device can be used for checking and signing the authorization response data, if the checking and signing are successful, the unlocking device can be recorded as a hardware key, and meanwhile, the identification of the unlocking device, such as a Media Access Control Address (MAC) and a public key, can be stored. Then, the electronic door lock can return an authorization success result to the unlocking device, and the unlocking device can display the authorization result through the display screen.
And S204, when the electronic door lock detects an unlocking action, sending first verification data to the unlocking equipment through the communication connection established between the electronic door lock and the unlocking equipment in the first near field communication mode.
Taking the first near field communication mode as an example for explanation, when the electronic door lock detects that a person touches a door lock touch key, the NFC card reader can be opened to perform NFC scanning; when the unlocking device is close to the door lock NFC scanning area, the electronic door lock is connected with the unlocking device through NFC after scanning is successful, and first verification data is sent to the unlocking device through the NFC connection channel, wherein the first verification data can be any data, such as a random number.
S205, the unlocking device receives first verification data through the communication connection established between the unlocking device and the electronic door lock in the first near field communication mode, generates first feedback data according to the first verification data, and returns the first feedback data to the electronic door lock.
After the unlocking device receives the first verification data, the first verification data and the identification of the unlocking device can be signed by using the private key of the unlocking device to obtain first feedback data, and then the first feedback data is sent to the electronic door lock. The first verification data and the identifier of the unlocking device can be encrypted by using the agreed key or the data interaction key calculated in real time by adopting an agreed key calculation mode to obtain the first feedback data.
S206, the electronic door lock receives the first feedback data, and whether the unlocking device is the bound unlocking device or not is verified according to the first feedback data.
After receiving the first feedback data, the electronic door lock can use a pre-stored public key of the unlocking device to check and sign the first feedback data; or decrypting the unlocking equipment by using a pre-agreed secret key, comparing the equipment identifier and the verification data obtained by decryption with the bound unlocking equipment identifier and the verification data which are stored in advance, and judging the unlocking equipment as the bound unlocking equipment after the verification is successful or when the comparison result is consistent.
And S207, if the electronic door lock verifies that the unlocking device is the bound unlocking device according to the first feedback data, returning a verification passing message to the unlocking device.

And S208, after receiving the verification passing message, the unlocking device sends a connection signal to the electronic door lock.
Wherein, the connection signal may carry an agreement field generated based on the first verification data and/or the first feedback data.
Explaining by using the second near field communication mode as Bluetooth, after the first feedback data verification is passed, the unlocking device starts Bluetooth broadcasting, and the Bluetooth broadcasting information of the unlocking device can carry an agreement field of the first NFC unlocking stage verification information. For example, when the authentication information in the NFC unlocking stage is 123456, the pre-agreed field may be defined as 123, and the specification of the agreed field is not specifically limited in this embodiment. The NFC verification stage verifies the connecting equipment once, and then in the connection process of the Bluetooth connection mode, the NFC verification information protocol field is used, so that the safety of the connecting equipment is confirmed, and the safety of Bluetooth connection of the electronic door lock is improved.
S209, the electronic door lock extracts an agreement field generated based on the first verification data and/or the first feedback data from the connection signal sent by the unlocking device so as to identify the verified bound unlocking device according to the agreement field.
The electronic door lock starts Bluetooth scanning, the effective time of the Bluetooth scanning can be set, and if legal unlocking equipment is not scanned within the effective time, unlocking fails. After the Bluetooth of the electronic door lock scans the Bluetooth broadcast sent by the unlocking equipment, the protocol field carried in the broadcast information is extracted, and then the protocol field is compared with the protocol field stored by the electronic door lock, if the protocol field is matched with the protocol field stored by the electronic door lock, the electronic door lock can determine that the unlocking equipment is a legal hardware key, and at the moment, the electronic door lock can establish Bluetooth connection with the unlocking equipment.
And S210, after the verification is passed, the electronic door lock sends second verification data to the unlocking device through the communication connection established between the electronic door lock and the unlocking device in the second near field communication mode.
And S211, the unlocking device receives second verification data through the communication connection established between the unlocking device and the electronic door lock in the second near field communication mode, generates second feedback data according to the second verification data, and returns the second feedback data to the electronic door lock.
In a possible design, the unlocking device may use its own private key to sign the second verification data and/or the unlocking device identifier to obtain the second feedback data, or use a predetermined key to encrypt the second verification data and/or the unlocking device identifier to obtain the second feedback data, and then return the second feedback data to the unlocking device.
S212, the electronic door lock receives the second feedback data, then the unlocking equipment is verified according to the second feedback data, and unlocking is carried out after verification is passed.
After the electronic door lock receives the second feedback data, based on a verification protocol agreed with the unlocking device in advance, the public key of the unlocking device can be used for verifying the signature of the second feedback data, or the agreed key is used for decrypting the second feedback data to verify whether the decrypted data is consistent with the agreed data, and the electronic door lock is unlocked after the signature is verified successfully or the decrypted data is successfully decrypted.
In one possible design, the second verification data sent by the electronic door lock to the unlocking device includes an agreement field generated based on the first feedback data, and the unlocking device identifies the bound electronic door lock verified by the first near field communication mode based on the agreement field.
Specifically, a certain number of bits of the first feedback data may be used as the agreement field, for example, when the first feedback data is ABCDE, the first three bits may be defined as the agreement field, and the agreement field is ABC, or a function may be defined to transcode the first feedback data to obtain the agreement field. This embodiment is not particularly limited. In this kind of implementation, because the agreement field of the verification data in the first verification process has been used to the second verification process, then only when dual verification all passes, the action of just can carrying out safety unblanking, this to a great extent has improved the degree of difficulty of cracking the unblanking, because subsequent bluetooth is unblanked and is verified some data that have still used NFC to unblank to verify, make only NFC unblank attack and bluetooth attack, can not realize cracking and unblanking, the degree of difficulty of cracking of making up has also improved simultaneously.
According to the unlocking method provided by the embodiment, the unlocking equipment such as the encryption bracelet is bound as the hardware key of the electronic door lock, the unlocking equipment is verified in the first verification mode, then the unlocking equipment is verified in the second verification mode, and in the second verification process, the protocol field of the data in the first verification stage is used, so that the unlocking can not be cracked only by conducting attack in a certain verification mode, meanwhile, the difficulty of combination and cracking is improved, and the difficulty of cracking the unlocking is improved to a great extent.
Fig. 3 is a schematic flow chart of another unlocking method provided by an embodiment of the present invention, where the embodiment mainly describes a specific interaction process between an electronic door lock and an unlocking device when a bluetooth channel binding key is selected in the above embodiment, and as shown in fig. 3, the method provided by the embodiment may include the following steps:
s301, when the unlocking device is added as a hardware key, after the electronic door lock is connected with the unlocking device through Bluetooth, a pairing request is sent to the unlocking device, and the pairing request comprises a second key parameter.
When a hardware key is added, a communication channel can be selected from the communication channels to establish communication connection, and when a Bluetooth channel is selected for key binding, in order to prevent packet capturing in the air and increase security, the Bluetooth connection can be established in the following mode.
Use equipment of unblanking to explain for encrypting the bracelet as an example below, it has the security chip that has data storage processing ability to embed before the encryption bracelet dispatches from the factory, and is concrete, and the user can press making it of encrypting the bracelet long and get into and pair the broadcast state, and at this moment, the security chip of encrypting the bracelet can generate and pair the sign indicating number and show on encrypting the bracelet screen, and wherein, should pair the sign indicating number and can be arbitrary random number. Meanwhile, the encryption bracelet may encrypt the agreement field of the random code by using a contract key, and carry the encrypted agreement field in the broadcast data of the bluetooth, for example, when the pairing code is 123456, 123 in 123456 is encrypted as ABC, and ABC is carried in the broadcast data of the bluetooth. The user can touch the electronic lock to make it get into the bluetooth scanning state, then inputs complete pairing code in the electronic lock, like 123456, after the bluetooth of electronic lock scans data ABC in the encryption bracelet bluetooth broadcast, can use the agreed key of prestoring to decrypt it and obtain 123, verify whether 123 that the decryption obtained is the partial field of complete pairing code 123456, verify that after successful, the electronic lock can establish the bluetooth with encrypting the bracelet and be connected.
After the electronic door lock is connected with the encryption bracelet through Bluetooth, a pairing request can be sent to the encryption bracelet, and second key parameters included in the pairing request can include an encrypted basic key, a host machine MAC address and any random number R1. The basic key is the same encryption key carried by both the electronic door lock and the unlocking device when the electronic door lock leaves a factory, the host machine MAC address is the door lock MAC address, and the random number R1 can be any random number.
S302, after the unlocking device establishes Bluetooth connection with the electronic door lock, the unlocking device receives a pairing request sent by the electronic door lock, generates a preset secret key according to a second secret key parameter in the pairing request, and sends a pairing response to the electronic door lock after the preset secret key is generated.
After the encryption bracelet receives a pairing request sent by an electronic door lock, an encrypted basic key can be decrypted by using a key carried in factory and identical with the electronic door lock, and after the basic keys of the two parties are confirmed to be identical, a preset key is generated according to a second key parameter in the pairing request, wherein the preset key is used for generating a data interaction key in a handshaking process with the electronic door lock.
Optionally, the generating, by the unlocking device, the preset key according to the second key parameter in the pairing request includes: the unlocking device generates a preset key according to the basic key, the host MAC and the random number R1.
S303, the electronic door lock receives the pairing response sent by the unlocking device and generates a preset key according to the second key parameter.
After receiving the pairing response, the electronic door lock is successfully paired with the encryption bracelet in a Bluetooth mode, and the MAC address of the encryption bracelet can be acquired through a Bluetooth channel for storage, so that pairing and binding of the electronic door lock and the encryption bracelet are completed; and the electronic door lock also generates a preset secret key, so that the electronic door lock and the application layer of the encryption bracelet are paired.
