Accountable and privacy-preserving wireless access network authentication method and authentication system

Abstract

The invention discloses an accountable and privacy-protected wireless access network authentication method, which comprises the following steps: step 1, the user group manager registers with the network operator; step 2, the user contacts the user group manager for Authentication, so that the user becomes a user in the group; Step 3, if the user is found to be compromised, the network operator cancels the compromised user; Step 4, the user successfully accesses the wireless network; Step 5, when there are two or two When the above signatures need to be authenticated, the access point performs batch signature verification on these signatures; step 6, the legal authority determines the user responsible for the specific communication session. The invention also discloses an authentication system for realizing an accountable and privacy-protected wireless access network authentication method, including: a network operator, an access point, a user group manager, users in the group and legal authority. It has the ability to limit the trust degree of each entity item, effectively avoiding the problem of custody and single point of failure.

Description

technical field [0001] The invention relates to a wireless communication technology, in particular to an accountable and privacy-protected wireless access network authentication method and an authentication system thereof. Background technique [0002] The popularity of wireless access networks has greatly improved the quality of life and work efficiency, allowing users to access the network almost anytime and anywhere. With the growing demand for wireless access networks, wireless access networks begin to play an irreplaceable role in life. But what is worrying is that risks are ubiquitous in wireless access networks. These risks include sensitive information disclosure by inexperienced or unsuspecting users, easy implementation of wireless signal interception, and rapid maturity of monitoring equipment. Therefore, if such a wireless access network needs to be deployed on a large scale, security, privacy, accountability and efficiency are the most important issues to be co...

AI Technical Summary

Problems solved by technology

Second, existing wireless access networks cannot provide accountability while maintaining privacy

There are currently no privacyaware cryptographic primitives available that can be directly deployed to achieve the above goals
