In practice, the present invention mainly provides the coding method of the network identity identification code (eID_code) in a network electronic identity. There is no related solution in the present network identity management field.
The coding method of eID_code is the Base64 coding of the 32-byte-long binary information calculated by the user's identity number, the username and the 128-byte-long random number string, according to the 256-byte-long cryptographic hashing algorithm (national encryption SM3 or SHA256), having characteristics of uniqueness, low-cost calculation and irreversibility in order to achieve the purposes of network identity management and privacy protection.
There is a one-to-one correspondence between the network identity identification code (eID_code), representing the identification code of citizenship corresponding to the eID, and the citizenship. The eID_code itself doesn't include any user's identity information, which ensures the personal identity authenticity and effectively protects the identity information from being exposed. In the future, in the application of the eID in all industries and all fields, eID_code will be the only one identification code for the information/conversation in all kinds of application services. Therefore the coding method of the eID_code is the core link in the network identity management.

This is convenient to interconnect among the different identity service systems, protects the network application security and the citizen identity information privacy, and lays a strong foundation for establishment of unified network identity management and service ecosystem.
The present invention combines the needs of the network development situation and the network identity management. To carry out the network identity management in our country and provide the privacy information protection for citizens, the present invention raises a coding method of the network identity identification (eID_code), according to the 256-byte-long cryptographic hashing algorithm (national encryption SM3 or SHA256).
The present invention widely supports to solve the application which is related to the e-government, the e-commerce, the e-bank and the online payment carried by the eID.
Below are the definitions used in the present invention:
Network electronic identity (eID): The eID, the abbreviation of electronic identity, is the network electronic identity in the citizen identity management system. It is based on the cryptography, carried by smart card chip, and uniformly issued to citizens to confirm remote identity on the network by public security organs. It has the characteristics of authority, consistency and universality.
Network identity identification code (eID_code): There is a one-to-one correspondence between the eID_code, a network identity identification code, and citizenship. The eID_code itself doesn't include any user's identity information. The length of the eID_code is 48 bytes long, and the type of it is string, the numbers between each byte connecting with each other in turn and there being no blanks or any other characters (such as _,  ̃, , \, /, &, etc).
SM3 algorithm—its full name is SM3 cryptographic hash algorithm. SM3 hash algorithm pads, iterates and compresses the message m, length of which is l (l<264) bits, to generate a hash value, length of which is 32 bytes long (256 bits).
SHA256—SHA (Secure Hash Algorithm) is a series of cryptographic hash function, designed by the National Security Agency (NSA) and released by the U.S. National Institute of Standards and Technology NIST). NIST released three additional SHA variants, and each variant has longer information abstract. They are named for their information length (measured by bits), added behind the old name: “SHA-256”, “SHA-384” and “SHA-512”. They were released in the draft FIPS PUB 180-2 in 2001, and then passed the audit and evaluation.
Base64 coding—According to the RFC2045 definition, Base64 is defined as that, the Base64 Content-Transfer-Coding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable.
The coding object of the network identity identification (eID) is all the netizens who use network to go surfing inside the People's Republic of China. The coding method formats of network identity identification code (eID_code) are as follows:
(1) The coding format:

















eID_version
BHash_Value
eid_code_rvb










The definitions are as follows:
eID_version: It means the version number of the eID, consuming one byte, and its type is string.
BHash_value: It means hash value, consuming 44 bytes, and its type is string. It is the Base64 coding of the 32-byte-long binary information calculated with the user's identity number (IDnumber), the username (name), the valid certificate type (type) and the 128-byte-long random number string (random_eid_hash), according to the national encryption SM3 (or SHA256) cryptographic hashing algorithm. It is named as BHash_Value. The computational formula is as follows:

BHash_Value=Base64{(SM3|SHA256)[append(IDnumber∥name∥type∥random_eid_hash)]}  (1)

The “valid certificate type” is as shown in Table 1.

eid_code_rvb: It means reservation byte, consuming three bytes, and its type is string. Its default is to be filled all with 0.
This is the computational formula of the eID_code as follows:

eID_code=append(eID_version∥BHash_Value∥eID_code_rvb)  (2)

After the users have applied for the eID carrier through the relevant channels, they need to activate the carrier by the client in the network, and to obtain the network identity identification code (eID_code). The concrete generating steps are as follows:
Firstly, the server generating a 128-byte-long random number through a true random number generator (TRNG) in advance, and assigning the value to the string type variable random_eid_hash to generate the 3-byte-long reservation byte eid_code_rvb with the string type, and its default is to be filled with 0. When receiving the request to generate an eID_code from the client, the server will reading the version number eid_version, the user's identity number (IDnumber), the username (name) and the valid certificate types (type) from the request information.
Then, to ensure the uniqueness of the user's eID_code, the server will launching its audit procedures, and auditing whether the user has owned the valid eID before, which means having generated the valid eID_code. The server will refusing the user who has owned the valid eID to generate a new eID_code, and will informing the user of the information “failed audit and having applied for eID”.
If the audit is passed, the server connecting the IDnumber, name, the type, the random_eid_hash to be padded, iterated and compressed with the SM3 (or SHA256 arithmetic), and generate a hash value of 32-byte-long binary information. Then the server performing Base64 coding to have a 44-byte-long string, and connecting the string, the eID_version and the eid_code_rvb to comprise the eID_code.
Finally, the server returning the eID_code to the client. If the return information is received that the client has successfully written the eID_code into eID, the server storing the eID_code into the database, and informing the user of a message that the eID_code can be checked; otherwise informing the client of the information “the eID_code is failed to be generated”.
The proof technique of the network identity identification code is as follows:
(1) Initialization, reading the user's identity number (IDnumber), the username (name), the valid certificate types (type) and the 128-byte-long sequential file of the card (card_sn).
(2) If the request of writing the eID_code into from the client is received, then reading the BHash_Value and turning to step 3, otherwise turning to the waiting process.
(3) Calling the connection function append( ), and making the string type variable Hash_origin=append (Idnumber, name, type, card_sn).
(4) The Hash_origin being padded, iterated and compressed by cryptographic hash algorithm SM3 (or SHA256) to generate a hash value of 32-byte-long binary information, and assigning the value to the Hash_card, which is:

Hash_card=(SM3|SHA256)[append(IDnumber∥name∥type∥card_sn)]

(5) Encoding the Hash_card by Base64 coding to get a 44-byte-long string and assigning the value to the BHash_card, which is BHash_card=Base64{Hash_card}.
(6) Activating the data consistency checking instruction eid_code_verify in the card, and performing checking between BHash_carda and BHash_Value. If the result is identical, then agreeing the request of writing the eID_code in. If not, refusing the request of writing eID_code in and informing the user of the information that “the request of writing eID_code in is wrong”.
After the user has applied for and activated the eID carrier with the valid certificates through the relevant channels, the eID_code in the relevant eID management system can be queried through the network.

For the convenience of description, the computational formula of the eID_code is illustrated with the following formula (1) and (2). The implementation steps to generate the eID_code are illustrated with the FIG. 1. The steps of data consistency checking in the card are illustrated with the FIG. 2.
The computational formula of the eID_code is as follows:

















eID_version
BHash_Value
eid_code_rvb










BHash_Value=Base64{(SM3|SHA256)[append(IDnumber∥name∥type∥random_eid_hash)]}  (1)

eID_code=append(eID_version∥Hash_Value∥eID_code_rvb)  (2)

The steps to generate the network identity identification code (eID_code) are as follows:
(1) Initialization, generating a 128-byte-long random number through the true random number generator (TRNG), and assigning the value to the string type variable random_eid_hash to generate the 3-byte-long reservation byte eid_code_rvb with the string type, and its default is to be filled with 0;
(2) When receiving the request to generate a eID_code from the client, the server reading the version number eid_version, the user's identity number (IDnumber), the username (name) and the valid certificate types (type) from the request information;
(3) The server launching its audit procedures. If the audit is passed, then turning to step 4, otherwise informing the user of the information “failed audit and having applied for eID”;
(4) Calling the connection function append( ), and making the string type variable Hash_origin=append(IDnumber, name, type, random_eid_hash);
(5) The Hash_origin being padded, iterated and compressed by SM3 (or SHA256 arithmetic) to generate a hash value of 32-byte-long binary information, and assigning the value to the Hash_Value, which is: Hash_Value=(SM3|SHA256)[Hash_origin];
(6) Encoding the Hash_card by Base64 coding to get a 44-byte-long string and assigning the value to the BHash_Value, which is BHash_Value=Base64[Hash_Value];
(7) Calling the connection function append( ) to connect the eID_version, BHash_Value and eid_code_rvb, assigning the value to the eID_code, which is eID_code=append(eID_version, BHash_Value, eid_code_rvb);
(8) Returning the eID_code to the client. If the return information that the eID_code has been written successfully to the eID from the client is received, turning to the step 9, otherwise informing the client of the information “the eID_code is failed to generate”;
(9) Storing the eID_code into the database, and informing the user of a message that the eID_code can be checked.
The steps of the eID_code checking data consistency in the network electronic identity are as follows:
(1) Initialization, reading the user's identity number (IDnumber), the username (name), the valid certificate types (type) and the 128-byte-long sequential file (card_sn);
(2) If the request of writing the eID_code in from the client is received in the card, then reading the BHash_Value and turning to step 3, otherwise waiting;
(3) Calling the connection function append, and making the string type variable Hash_origin=append (Idnumber, name, type, card_sn);
(4) The Hash_origin being padded, iterated and compressed by cryptographic hash algorithm SM3 (or SHA256) to generate a hash value of 32-byte-long binary information, and assigning the value to the Hash_card, which is:

Hash_card=(SM3|SHA256)[append(IDnumber∥name∥type∥card_sn)];

(5) Coding the Hash_card by Base64 coding to get a 44-byte-long string and assigning the value to the BHash_card, which is BHash_card=Base64[Hash_card];
(6) Activating the data consistency checking instruction eid_code_verify in the card, and performing checking between BHash_carda and BHash_Value. If the result is identical, agreeing to write the eID_code into the request. If not, refusing the request of writing eID_code in and informing the user of the information that “the request of writing eID_code in is wrong”.
The above methods of the present invention could achieve the following features in the security and privacy protection aspects:
(1) Uniqueness
The identification code of the network electronic identity eID_code is generated according to the citizen's valid identity number, type, name and random number. It realizes the one-to-one correspondence between the eID_code and the citizenship. The 256-byte-long cryptographic hashing algorithm is used to ensure the uniqueness of the eID_code and internal data consistency checking instruction is used to ensure the uniqueness of the citizen's valid eID_code.
(2) Privacy
The eID_code itself doesn't include any user's identity information (such as the valid identity number, the type, the name and so on), which protects citizen's identity privacy information from being exposed.
(3) Irreversibility
The eID_code is generated by 256-byte-long hash cryptograph algorithm (national encryption SM3 or SHA256) and then is coded by Base64 coding. Because the inverse calculation of the hash cryptograph algorithm is not applicable, the Base64 coding will make the original information difficult to be identified. And because the 128-byte-long random number is introduced as a factor in the process of calculation, it is impossible to use brute force. Therefore, the generated eID_code is irreversibility.
(4) Replaceability
As the same with the fixed coding of the identity card number, once the correspondence relationship between the eID_code and the citizen's personal identity information is leaked, a new 128-byte-long random number will be generated through the citizen's individual application. The new eID_code will be calculated to replace the old one to keep protecting the user's privacy.
(5) Supporting Security Verification Inside the Card
The special cos instruction eid_code_verify is designed to realize the security verification in the card for the card owner's identity consistency. There is an online security verification process designed for the card owner's identity consistency.
By means of the method for generating and check-controlling a network identity identification code in a network electronic identification card, because the coding method is that the Base64 coding of the 32-byte-long binary information is calculated with the user's identity number, the username and the 128-byte-long random number string, according to the 256-byte-long cryptographic hashing algorithm (national encryption SM3 or SHA256), this coding method has the characteristics of uniqueness, low-cost calculation and irreversibility and achieves both the purposes of managing a network identity and privacy protection. At the same time, there is a one-to-one correspondence between the network identity identification code (eID_code), representing the identification code of citizenship corresponding to the eID, and the citizenship. The eID_code itself doesn't include any user's identity information, which ensures the personal identity authenticity and effectively protects the identity information from being exposed. On the other hand, the present invention analyzes all kinds of identity relevant information in the network identity management and service to give the unified rules of the eID_code coding method and to approve, exchange, preserve and manage the identity information. This is convenient to interconnect among the different identity service systems, and effectively protects the network application security and identity information privacy of citizens. The method is convenient and quick in use, has stable and reliable working performance, and has a wide application range, thereby laying a strong foundation for establishment of unified network identity management and service ecosystem.
In this specification, the present invention has been described with reference to specific embodiments. However, obviously modifications and variations still can be made without departing from the spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
