An identity authentication method, device and system

Abstract

The invention provides an identity authentication method, device and system. The method includes: receiving request information sent by a client; sending the request information to a unified identity authentication module, causing the unified identity authentication module to sign the request information to obtain signature request information; receiving the unified identity authentication The signature request information returned by the module; calling the unified identity authentication module to perform signature verification processing on the signature request information to obtain a signature verification result; receiving the signature verification result returned by the unified identity authentication module. The above technical solution no longer needs to configure the identity authentication service program for the application server, but calls the unified identity authentication module to complete the digital signature verification process. The unified identity authentication module can provide digital signature verification services for each due server, which facilitates the unified management of digital signature verification and saves system development costs.

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...
