Using a key lease in a secondary authentication protocol after a primary authentication protocol has been performed

摘要

The present invention provides a method and system for using a key lease in a secondary authentication protocol after a primary authentication protocol has been performed. In one embodiment, the primary authentication protocol comprises a strong, secure, computationally complex authentication protocol. Moreover, the secondary authentication protocol comprises a less complex (compared to the primary authentication protocol) and less secure (compared to the primary authentication protocol) authentication protocol which can be performed in a length of time that is shorter than a length of time required to perform the primary authentication protocol. In one embodiment, a wireless client electronic system (WC) completes the primary authentication protocol with a wireless network access point electronic system of a wireless network (AP). When the WC is required to authenticate with another AP, the WC authenticates itself with another AP by using the secondary authentication protocol. However, the WC is required to periodically complete the primary authentication protocol, guarding against the possibility that the secondary authentication protocol may be exploited by an unauthorized intruder to attack the wireless network. In one embodiment, a third party technique is implemented to store a key necessary to perform the secondary authentication protocol.
