WLAN access access control system and method based on multi-password authentication

Abstract

The present invention proposes a WLAN access control system and method based on multi-password identity authentication, which aims to take into account the access control and access control characteristics of the requester, improve the security of the requester's data communication, and reduce the control system. The implementation steps are as follows: the identity configuration module configures the identity identifier of the requester and the corresponding password and network access rights; the link negotiation module establishes a link with the requester; the master key calculation sub-module calculates the password corresponding to the password set For the master key set; the key negotiation submodule exchanges key materials with the requester and receives the information integrity check code; the temporary key calculation submodule calculates the temporary key set; the identity comparison submodule determines the identity of the requester Identifier; the authentication confirmation sub-module confirms to the requester that the identity authentication is passed; the access control module performs access control on the requester according to the network access authority corresponding to the requester's identity identifier.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a WLAN access and access control system and method, in particular to a WLAN access access control system and method based on multi-password identity authentication and key negotiation. Background technique [0002] WLAN (Wireless Local Area Network) is a computer local area network built with wireless channels as the transmission medium. It can be divided into personal and enterprise applications. The sender is the controller of the personal WLAN, and the requester is the user of the personal WLAN. [0003] Password-based identity authentication and key exchange is a kind of protocol that solves the problem of two parties at both ends of the network confirming each other's identity and conducting secure communication. This type of protocol usually assumes that the two parties in communication share a secret value to realize identity authentication and key exchange f...

Problems solved by technology

The requester of the known device identifier of this invention can use different passwords, which improves the security of the data communication of the requester, but the disadvantage is that the requester of the unknown device identifier can only use the same password, resulting in the request or the security of data communication cannot be guaranteed

The advantage of this solution is that the requester's access rights can be pre-configured without relying on the requester's device identifier, which reduces the complexity of access rights configuration, but its disadvantage is that an additional verification server is required to verify the requester's identity and store access profiles, increasing the cost of the system

Cause access control system and access control system can not be used together, lack of ease of use
