Abstract
The present invention provides a method and system for performing an authenticated Diffie-Hellman key agreement protocol over a network where the communicating parties share a secret key with a third party. In one embodiment, the network is a wireless network, wherein a wireless client electronic system (WC) and a network access point electronic system (AP) are the parties executing the authenticated Diffie-Hellman key agreement protocol. In this embodiment, the WC and the AP exchange a shared secret key for encrypting wireless communications between the wireless client electronic system and the network access point electronic system. In one embodiment, the WC shares a first secret key with a RADIUS server of the network. Similarly, the AP shares a second secret key with the RADIUS server of the network. The first and second secret keys are utilized for performing an authentication protocol.
