Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
The invention provides a synchronous calling user identity authentication method based on a block chain, which registers a user registration intelligent contract based on the block chain through a user side,
according to the verifiable random number, the digital signature is carried out by the user terminal,
according to the user authentication intelligent contract of the block chain, the user authentication intelligent contract is called by the identity authentication service end to verify the validity of the digital signature and whether the user exists in the user registration intelligent contract or not,
and obtaining a verification result through the identity authentication server.
The method of the invention can verify the random number to carry out digital signature through the user side, registers the user to register the intelligent contract based on the block chain, calls the user authentication intelligent contract through the identity authentication service side to verify the validity of the digital signature and whether the user exists in the user registration intelligent contract, and obtains the verification result through the identity authentication service side, namely, calls the intelligent contract through the identity authentication service side to check the validity of the digital signature and whether the user exists in the user registration intelligent contract, and does not wait for the confirmation of the block chain transaction, but directly adopts the verification result of the intelligent contract to the rule, so that the asynchronous call is changed into synchronous call, the delay is reduced, and the realization complexity is reduced.
In specific application, in some embodiments of the method, the method takes the example that the user side APP synchronously calls the identity authentication server side to prove the self identity and obtain the access token, the identity authentication server directly calls an intelligent contract to verify whether the digital signature of the user side is valid or not and whether the user identity is valid or not, global sharing and unified identity authentication of the user identity are realized by using a block chain, and meanwhile, low-delay authentication response and a light user authentication framework are realized. The specific process is as follows:
step 1: and the user registration intelligent contract registered to the block chain through the user side is added to the white list on the chain. The user registers the self public key to the user registration intelligent contract, and the public key in the white list is used for verifying the digital signature of the user when the user identity is verified by using the user authentication intelligent contract subsequently.
And 2, step: the verifiable random number is generated by the user side to replace a verifier in an interactive verification mode, such as the random number generated by an identity authentication server, and the verifiable random number is used for carrying out digital signature and is sent to the verifier, namely the verifiable random number is used for applying for an access token. Where verifiable random number V = HASH (timestamp T, user public key); v is digitally signed by the user terminal, digital signature S = SIG (V, user private key), function SIG () represents a digital signature algorithm, such as SM2.
And step 3: and calling a user authentication intelligent contract through the identity authentication server to verify the identity of the user. The intelligent contract for user authentication is called by taking the 'V + timestamp T + digital signature S' as a parameter, the intelligent contract verifies the validity of the digital signature and whether the user exists in the intelligent contract for user registration, and the verification result is written into the block chain whether the verification is passed or not. The intelligent contract verification process using user authentication is as follows:
judging whether the public key of the user exists in a white list, namely whether the user registers in an intelligent contract;
judging whether the digital signature of the verifiable random number is valid;
a determination is made whether the timestamp of the verifiable random number is expired, i.e., the timeout time is less than a predetermined value.
If the three logics pass, returning to the identity authentication server end to pass the identity authentication of the user, otherwise, returning to the authentication failure.
For timestamp timeout check: whether the time stamp is overtime or not is independently checked by each blockchain consensus node according to the system time of the node. Since there may be differences in system time for each node, redundant fault tolerance is considered. As long as the time difference between the system clocks of the user side APP and each node is smaller than a threshold (i.e. timeout). For example, the threshold is set to 5 minutes, the user side APP generates a verifiable random number by using the local system time, and each node checks the difference between the own system time and the timestamp in the verifiable random number, and if the difference is less than 5 minutes, the verification is passed.
The return value of the intelligent contract which calls the user authentication is checked by the identity authentication server, and if the verification passes (true), an access token is generated locally.
And 4, step 4: and returning the generated access token to the user side APP. The common access token format is JWT, and has a field similar to a digital signature, which is related to the selected encryption method, and the encryption algorithm may be selected from asymmetric, symmetric, or hash, etc. And the authentication server generates the access token in a pre-agreed format, encrypted, e.g., by signing the JWT token with the SM2 digital signature.
The identity authentication server returns the access token to the user APP, and is a response to the application access token call. The identity authentication server shields the access to the block chain, and for the user side APP, the identity authentication server is called synchronously by using the block chain private key.
By the method, the user side APP logs in once, the synchronous calling of the identity authentication server enables the user APP to use the block chain private key to exchange the access token, and can support the chain mark in the identity authentication process and the forgery-resistant verification of the user identity and the non-repudiation of the login behavior.
The user identity authentication process does not depend on the confirmation of the blockchain transaction any more, so that the response time of the user identity authentication based on the blockchain private key is greatly shortened, and the software architecture is greatly simplified by removing an asynchronous mechanism.
Meanwhile, the invention also provides a synchronous calling user identity authentication system based on the block chain, a user side interaction module and an identity authentication server side interaction module,
the user terminal interaction module registers the user registration intelligent contract based on the block chain according to the user terminal indication, generates a digital signature of the user terminal according to the verifiable random number,
according to the user authentication intelligent contract of the block chain, the identity authentication service terminal interaction module calls the user authentication intelligent contract according to the indication of the identity authentication service terminal, verifies the validity of the digital signature and whether the user exists in the user registration intelligent contract or not, and returns the verification result to the identity authentication service terminal. The information interaction, execution process and other contents between the modules in the system are based on the same concept as the method embodiment of the present invention, and specific contents can be referred to the description in the method embodiment of the present invention, and are not described herein again. Similarly, the system can carry out digital signature according to the verifiable random number of the user end through the user end interaction module, based on the intelligent contract registered by the block chain registered user, the validity of the digital signature and whether the user exists in the intelligent contract registered by the user are verified by calling the intelligent contract authenticated by the identity authentication service end interaction module, and the verification result is returned to the identity authentication service end, namely the identity authentication service end interaction module indicates to call the intelligent contract to check the validity of the digital signature and whether the user exists in the intelligent contract registered by the user through the identity authentication service end, the confirmation of block chain transaction is not waited, but the verification result of the rule of the intelligent contract is directly adopted, so that the asynchronous call is changed into synchronous call, the delay is reduced, and the realization complexity is reduced.

the at least one processor is configured to invoke the machine readable program to execute the block chain-based synchronous invocation user identity authentication method.
The contents of information interaction, readable program process execution and the like of the processor in the device are based on the same concept as the method embodiment of the present invention, and specific contents can be referred to the description in the method embodiment of the present invention, and are not described herein again. Similarly, when the processor of the device executes the readable program, the processor can verify the random number through the user terminal to carry out digital signature, based on the block chain registered user intelligent contract, the identity authentication service terminal calls the user authentication intelligent contract to verify the validity of the digital signature and whether the user exists in the user registered intelligent contract, and the identity authentication service terminal obtains the verification result, namely when the identity authentication service terminal calls the intelligent contract to check the validity of the digital signature and whether the user exists in the user registered intelligent contract, the verification result of the block chain transaction is not waited, but the verification result of the rule of the intelligent contract is directly adopted, so that the asynchronous call is changed into synchronous call, the delay is reduced, and the realization complexity is reduced.
