Identity authentication method, device and system

Abstract

The invention provides an identity authentication method, device and system. The method comprises the following steps: receiving request information sent by a client; sending the request information to a uniform identity authentication module, and enabling the uniform identity authentication module to carry out signature processing on the request information to obtain signature request information; receiving the signature request information returned back by the uniform identity authentication module; calling the uniform identity authentication module to carrying out signature identification processing on the signature request information, so as to obtain a signature identification result; receiving the signature identification result returned back by the uniform identity authentication module. With the adoption of the technical scheme, an identity authentication service procedure does not need to be specially configured for an application server, but the uniform identity authentication module is called to finish the signature identification processing on digital signatures. The uniform identity authentication module can realize the aim of providing signature identification services of the digital signatures for each application server, and uniform management of signature identification of the digital signatures is convenient to realize; meanwhile, the development cost of the system can be saved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an identity authentication method, device and system. Background technique [0002] Digital signature verification is a common method for authenticating the identity of both parties in Internet interaction. Such as figure 1 As shown, in digital signature verification, the sender uses a hash function to generate a message digest from the message text when sending a message, and then encrypts the digest with its own private key, and the encrypted digest will be The digital signature as the message is sent to the receiver together with the message; the receiver first uses the same hash function as the sender to calculate the message digest from the received original message, and then uses the sender's public key To decrypt the digital signature attached to the message, if the two digests are the same, the receiver can confirm that the digital signature belongs...

AI Technical Summary

Problems solved by technology

[0003] With the development of Internet technology and the continuous improvement of informatization level, the company has built more and more information systems to support its own business development. Usually, the information system and the identity authentication module have a one-to-one tight coupling relationship, so corresponding to the information system There are more and more identity authentication modules being built, which brings unprecedented challenges to the company's standardized management of identity authentication, reduces the efficiency of identity authentication management, and increases the cost of system development
