Detailed Description
The invention is further described below with reference to the accompanying drawings and examples:
currently, digital money (i.e., digital renmins in china) equivalent to physical money such as paper money and coins has been put into circulation in the market. Similar to physical currency, digital currency may also be carried in a "wallet" medium. As mentioned in the background, digital money wallets can be classified into soft wallets and hard wallets, but have some drawbacks.
In view of this, the present invention proposes a digital money hard wallet that determines the unique identity of the digital money wallet by correlating the device identity with the user identity.
Fig. 1 is a schematic diagram of a digital currency hard wallet according to the present invention.
The digital money hard wallet may include a control module 1, an identity storage module 2, a digital money wallet module 3, and an interface 4.
Wherein the control module 1 interacts with applications other than digital money hard wallets via the interface 4.
For example, the control module 1 may detect whether the use of a digital money hard wallet is triggered. The condition triggering the use of the hard wallet may be that the control module 1 detects that the NFC (Near Field Communication ) module is being used through the interface 4, the user has a need to use money; the triggering condition may also be that the control module 1 detects, through the interface 4, that there is an application in the device in which the digital money hard purse is located that invokes the payment SDK in the device, and that the user has a need to use money. The NFC module and the payment SDK are both installed on the device where the digital currency hard wallet is located.
The control module 1 also interacts with a CA (Certificate Authority ) center in the quantum security network through the interface 4, which interaction may be through a CA client installed on the device, to obtain the device identity certificate of the hard wallet, the identity certificate of the user, the digital certificate of the digital money hard wallet, etc.
The control module 1 can interact with a hard wallet application APP installed in a device where the digital currency hard wallet is located through an interface 4, the hard wallet application APP directly faces a user, receives an operation instruction of the hard wallet sent by the user, and applies for opening the digital currency hard wallet for example.
The control module 1 is connected with the identity storage module 2 and the digital currency wallet module 3, and performs related tasks such as data processing and sending in the digital currency hard wallet.
The control module 1 may be an FPGA (Field Programmable Gate Array ) chip.
The identity storage module 2 comprises a plurality of identity units, which may include a first identity unit 201, a second identity unit 202, and a third identity unit 203. Wherein the first identity unit 201 may be used to store device information of a hardware device being a digital money hard wallet, e.g. a chip, the device information of which may then be stored in the first identity unit 201; the second identity unit 202 may be used to store user information that owns the digital currency hard wallet; the third identity unit 203 may be used to store wallet credentials for digital currency hard wallets.
The identity storage module 2 may be divided into a plurality of identity units by software, and this may be implemented in hardware by deploying a hardware module and logically dividing the hardware module into a plurality of discrete units by software description. The identity storage module 2 may also implement multiple identity units by deploying multiple hardware modules, one for each identity unit. For example, the hardware module may be a Flash (Flash Memory) chip, which is one type of memory device, and is a Non-Volatile (Non-Volatile) memory, i.e., a flash memory, which is still capable of storing data for a long time in the event of a power failure.
In some embodiments, the identity storage module 2 may further include more identity units to store other identity information during use according to actual use conditions, and is not limited to the 3 identity units set forth herein, but the present invention is not limited to the number of identity units.
The digital money wallet module 3 is used to handle tasks related to digital money. For example, the digital-money wallet module 3 may include a money recording unit 301 for recording the amount of digital money currently in the digital-money hard wallet; the digital money wallet module 3 may further comprise a wallet identifying unit 302 for storing wallet identifications issued by wallet service providers.
Identity storage is realized in a one-time writing mode by identity units related to equipment and users in the identity storage module in the digital currency hard wallet, so that the non-tamper property of the identity is ensured. Meanwhile, the identity information is acquired from a CA center in the quantum security network, so that the uniqueness of the identity can be ensured, and further, the wallet digital certificate generated based on the equipment and the user identity is also unique.
The digital currency hard wallet is taken as a link in the field of financial transactions, and is different from an entity wallet in that the digital currency hard wallet needs to be registered in a financial system, and can participate in the financial transactions after being opened in the financial system, otherwise, the hard wallet is illegal, and the digital currency in the hard wallet belongs to invalid currency.
Therefore, the invention also provides a method for opening the digital currency hard wallet.
Corresponding to the digital currency hard wallet, the device where the digital currency hard wallet is located is provided with a hard wallet application APP which can access the hard wallet, so that the hard wallet is prevented from working independently. The user can initiate the opening application of the hard wallet through the APP. The hard wallet application APP can set login information such as account name and password, and the user cannot use the hard wallet without the login information.
FIG. 2 is a flow chart of the method for opening the digital money hard wallet of the present invention, which comprises the following steps:
step 1: the control module 1 performs an initialization configuration for the digital money hard wallet.
The initialization configuration includes: device information of the device in which the digital money hard wallet is located is written in the first identity unit 201. The device information may be a production serial number of the device or may be a device identity certificate obtained from a CA center in the quantum security network. Both the production serial number and the device identity certificate are unique across the network. It will be appreciated that other data that may be the unique identity information of the device (e.g., the network entry number of the device, etc.) may also be written as the device information in the first identity unit 201. In this embodiment, taking a device identity certificate obtained from a CA center in a quantum security network as an example, a method for opening a digital money hard wallet is described. The CA center in the quantum security network also stores the device information of the device when issuing the device information to the device where the digital currency hard wallet is located.
The device information is written to the first identity unit 201 in a write-once manner, and subsequently during operation of the hard wallet the device information can only be read and cannot be written to and overlaid again. In this way, the non-tamper ability of the device information is ensured. In some embodiments, the device information may be stored encrypted. The encryption key that encrypts the device information may be a true quantum random number; or may be an encryption key that is seeded with biometric information of the user that owns the hard wallet (e.g., biometric information such as fingerprint, voiceprint, face, etc.).
The initializing configuration further includes: user information is written to the second identity unit 202 that owns the digital money hard wallet. The user information may include a user identity credential that the user obtains from a CA center in the quantum security network through a CA client installed in the device. The user information is also written in a write-once manner in the second identity unit 202, which user information can only be read and not be written again for overwriting later on during operation of the hard wallet. Similarly, when issuing user information to a user of the digital money hard wallet, the CA center itself stores the user information of the user.
Step 2: after initializing the configuration, the control module 1 initiates an opening application for the digital money hard wallet to the digital money wallet server through the hard wallet application APP.
In an embodiment of the invention, the digital money wallet server may be a commercial bank or a third party financial institution that includes a central office authorized to operate digital money. The provisioning application includes the device information ID1 read by the control module 1 from the first identity unit 201, the user information ID2 read from the second identity unit 202, and the generated provisioning request req.
As shown in fig. 3, both digital-currency hard wallets and digital-currency wallet servers are deployed in a quantum-secure network environment.
Step 3: the digital currency wallet service provider receives an opening application of the digital currency hard wallet, authenticates equipment information and user information in the opening application, and generates a wallet identification and a wallet digital certificate for the digital currency hard wallet based on the equipment information and the user information after the authentication is passed.
The digital currency wallet service provider performs authentication on the device information and the user information in the opening application in a quantum-secure message code authentication mode. The specific process is as follows:
step 3-1: the control module 1 in the digital money hard wallet generates an authentication file M based on the provisioning application.
Specifically, the control module 1 obtains two groups of n-bit quantum random numbers locally, n can be 128 or 256, and the specific length of the quantum random numbers is determined according to the safety requirements in actual use. The control module 1 generates two n-order irreducible polynomials P according to the two random numbers 1 (x) And P 2 (x) Will not be about polynomialP 1 (x) The character string composed of each term except the highest term is marked as str1, and the irreducible polynomial P is expressed 2 (x) The string of coefficients for each term except the highest term is denoted str2.
The digital wallet negotiates with the digital wallet server for a key agreement to obtain shared keys a, b, c, d, e and f, respectively. The shared key may be obtained from a key center in the quantum security network or may be obtained from a key center local to a party.

The digital money wallet service provider uses the shared key c, d, e, f to decrypt the received authentication file M to obtain the hash valueString str1' and hash value +.>String str2'.
(b) Authentication device information ID1.
The process of the digital money wallet server authenticating the device information ID1 is as follows: generating a hash function based on string str1' and shared key aAnd performs hash calculation on the device information ID1' acquired from the CA center using the hash function to obtain a hash value +.>Hash value calculated +.>Hash value obtained by decryptionComparing, if the two hash values are consistent, comparingThrough; if the hash values are inconsistent, the comparison is not passed, and the opening flow of the digital currency hard wallet is terminated.
(c) Authentication user information ID2.
The process of the digital money wallet service to authenticate the user information ID2 is as follows: generating a hash function based on the string str2' and the shared key bAnd performs hash calculation on the device information ID2' acquired from the CA center using the hash function to obtain a hash value +.>Hash value calculated +.>Hash value obtained by decryptionComparing, if the two hash values are consistent, passing the comparison; if the hash values are inconsistent, the comparison is not passed, and the opening flow of the digital currency hard wallet is terminated.
After the digital money wallet service has authenticated both the device information and the identity information, a wallet identification and wallet digital certificate may be generated for the digital money hard wallet based on the device information and the user information. The wallet identification is used to indicate an address of the digital currency hard wallet. The wallet digital certificate is the identification of the digital currency hard wallet in the currency transaction process, applied by the digital currency wallet server to the CA center in the sub-security network, and issued to the digital currency wallet server by the CA center.
Step 4: the digital currency wallet service provider issues the wallet identification and the wallet digital certificate to the digital currency hard wallet, and simultaneously sends the wallet identification and the wallet digital certificate to the digital currency banknote issuing line for registration so as to ensure legal use of the digital currency hard wallet.

Thus, the digital currency bill issuing line can indirectly manage each digital currency hard wallet in the market by managing the digital currency wallet service provider, so that effective financial management is realized.
After registration, the digital currency issuing bank opens an account to the digital currency hard wallet corresponding to the digital certificate, and a digital currency hard wallet account is obtained. The successful account opening information is fed back to the digital currency wallet service provider, and the digital currency wallet service provider forwards the account opening success information to the digital currency hard wallet for the user to know. Thus, the final executive party of the change of the digital currency in the digital currency hard wallet is the digital currency bill row, and the change of the digital currency amount in the digital currency hard wallet account in the digital currency bill row ensures the unified management of the digital currency by the digital currency bill row.
The digital-currency hard wallet stores the received wallet identification in a wallet identification unit 302 in the digital-currency wallet module 3, which may be used to indicate the address of the digital-currency hard wallet. When a transaction of digital currency occurs, the user needs to address the digital currency hard wallet through the wallet identification.
The digital money hard wallet stores the received wallet digital certificate, which is the digital money hard wallet's identity during money transactions, in the third identity unit 203 in the identity storage module 2.
Step 5: the user deposits the initial amount of digital currency into the digital currency hard wallet to finish the opening of the digital currency hard wallet.
The user initiates an instruction to deposit an initial amount of digital currency into the digital currency hard wallet via the hard wallet application APP. The control module 1 reads the wallet digital certificate from the third identity unit 203 in the identity storage module 2, and the wallet identification from the wallet identification unit 302 in the digital money wallet module 3 based on the received instructions. The control module 1 sends the read wallet digital certificate, wallet identification and received user instruction to the digital currency note issuing bank through the wallet server, the wallet server and the digital currency note issuing bank authenticate the wallet digital certificate, the authentication method is consistent with the method of authenticating equipment information or identity information in the step 3, and the authentication is the authentication of the quantum security message authentication code, so that the detailed description is omitted. After the authentication is passed, the digital currency issuing bank performs a digital currency storage service according to the request of the digital currency of the initial amount in the user instruction. The storage service may be to exchange currency of the hard wallet corresponding to the user's RMB account for digital currency and store in the user's digital currency hard wallet account of the digital currency issuer.
After the digital currency bill issuing bank completes the storage business of the digital currency, the digital currency balance of the digital currency hard wallet account is sent to the hard wallet application APP via the wallet service provider, the control module 1 acquires the digital currency balance from the hard wallet application APP, and sends the balance to the currency recording unit 301 of the digital currency wallet module 3, so that the synchronization of the initial currency amount in the digital currency hard wallet is completed. Based on the initial monetary amount, the user may use the digital currency in the digital currency hard wallet or continue to store digital currency in the digital currency hard wallet.
In some embodiments, when the control module 1 detects that the NFC module or the payment SDK is invoked through the interface 4, it is indicated that there is a payment need for the device to which the digital currency hard wallet belongs, thereby triggering the control module 1 to interact with the currency recording unit 301. The control module 1 completes the transaction process of digital money in cooperation with the wallet facilitator and the digital money issuer via the hard wallet application APP, and synchronizes and records the digital money balance after the transaction is completed in the money recording unit 301. The transaction process of the digital currency is carried out among digital currency accounts of the digital currency bank, for example, a user to which the digital currency hard wallet belongs is taken as a buyer, and the digital currency in the digital currency hard wallet account of the digital currency bank is transferred to the digital currency account of the seller in the digital currency bank.
