Collaborative authentication method, system, device and storage medium

Abstract

The invention discloses a collaborative authentication method, system, device and storage medium, wherein the method includes: the authenticated party generates a first private key component and generates a private public key based on the first private key component, and assists the authenticating party in generating a second private key component key component; the auxiliary authenticator generates a collaborative public key based on the private public key and the second private key component, and applies for a certificate from the certificate issuer based on the collaborative public key and the identity information of the authenticated party, and returns the certificate to the authenticated party; The authenticator feeds back the message to be signed to the authenticated party in response to the authentication request sent by the authenticated party; the authenticated party cooperates with the auxiliary authenticator to generate a signature result based on the message to be signed and the first private key component and the second private key component, and sends The signature result and certificate are sent to the main certifier; the main certifier verifies the signature result and certificate. The technical solution provided by the invention can solve the technical problems of loss, abuse, lack of supervision and audit and safety risks in the authentication system in the prior art.

Description

technical field [0001] The invention relates to the technical field of network information security, in particular to a collaborative authentication method, system, device and storage medium. Background technique [0002] With the development of science and technology, communication technology has changed people's lives. In recent years, the number of users using communication equipment has continued to increase, and network information security technology has become more and more important. [0003] In the prior art, traditional identity authentication methods based on public key certificates rely on signature verification algorithms based on asymmetric encryption principles. In the traditional identity authentication method, firstly, the authenticated party initiates the authentication request process to the authenticating party; the authenticating party generates a local random number and sends it to the authenticated party; after the authenticated party signs with the ce...
