Security protocol authentication method supporting various digital identity information and system thereof

Abstract

The invention discloses a security protocol authentication method supporting various digital identity information and a system thereof, and the method comprises the steps: (1) first equipment receives an identity authentication request from second equipment, and carries out the analysis of the identity authentication request, so as to obtain a digital identity information type identifier of the second equipment and the digital identity information corresponding to the digital identity information type identifier; (2) the first device analyzes the digital identity information of the second device by using an analysis mode corresponding to the digital identity information type identifier of the second device, and verifies the analyzed digital identity information to obtain a verification result; and (3) the first device obtains public key information required by key negotiation in the next stage of the secure communication protocol from the digital identity information passing verification, and the process is ended. The technical problems that an existing security protocol cannot support a new standard format certificate and the compatibility of the new standard format certificate with an original standard certificate when the new standard format certificate is deployed can be solved.

Description

technical field [0001] The invention belongs to the technical field of information security and the field of Internet of Things communication, and more specifically relates to a security protocol authentication method and system supporting multiple digital identity information. Background technique [0002] With the continuous improvement of informatization, various government departments or enterprises and institutions have deployed a large number of business systems on the Internet, and conduct business data exchanges with other branches or partners through the Internet. These business data transmitted through the network are important digital assets of government departments or enterprises and institutions, and their confidentiality, authenticity, integrity and non-repudiation need to be guaranteed. At present, PKI technology is mainly used to meet these requirements. [0003] The PKI system is a combination of computer software and hardware, authoritative organizations a...
