System and method to provide enhanced security in a wireless local area network system

摘要

A system and method for enhancing Wireless Local Area Network (WLAN) security. The system and method include the generation of a pair of WEP-based encryption keys by a network access point. The key pair is transmitted to one or more clients associated with the access point after the client has been authenticated for access to the network. Each key is preferably randomly generated and the pair is further changed periodically. The timing of the changing of the keys is dependent upon the existing crypto analysis attack capabilities. Individual clients may have unique key pairs or a plurality of clients associated with an access point may share the key pair.
