Abstract

The invention relates to a unified identity authentication platform based on zero trust and confidential calculation, which comprises four stages, namely a communication establishment stage, a user registration stage, a function platform registration stage and a login and key negotiation stage, wherein the communication establishment stage is used for negotiating a symmetric key SK and establishing reliable communication between a user and a unified identity authentication platform; in the user registration stage and the function platform registration stage, a registration function verified by a unified identity authentication platform and a confidential calculation safety area and a function of constructing an anonymous authentication relation table are realized, and a legal user and a legal function platform are obtained; in the login and key negotiation stage, a function of negotiating a symmetric session key between a legal user and a legal function platform is realized, and the symmetric session key is used for encrypting subsequently transmitted privacy data. The method has the beneficial effects that the integrity and confidentiality of data in a running state are ensured; the low overhead and low time delay of the authentication process are ensured, and quick authentication is realized.

Description

technical field [0001] The invention relates to the field of confidential computing, in particular to a unified identity authentication platform based on zero trust and confidential computing. Background technique [0002] With the complexity of the network structure and the diversification of terminal equipment, IP networks are more vulnerable to a large number of new attacks. Insider threats account for nearly 75% of all security breach incidents, and the two major sources of insider threats are data leakage and privilege abuse, which account for 62% and 19% of threats respectively. In practical applications, the application scenario network structure includes three parts: user (U), unified authentication platform (UCP), and functional platform (FP). The request sent by the user to the target FP is legally authenticated by the UCP and then forwarded to the FP for confirmation. In this process, due to the widely dispersed geographical location of users and the considerati...
