Abstract  Abstract

1. A method operating at an access point, comprising the steps of:! receive the first request from the access terminal to establish a secure communication session through the access point; ! sending a key request message to the authentication device, where the key request message includes a locally obtained identifier of the first access point and a received identifier of the access terminal; and! receive the first master session key from the authentication device to establish a communication session between the access terminal and the access point, where the first master session key is a function of at least the identifier of the first access point and the identifier of the access terminal. ! 2. The method of claim 1, wherein the key request message also includes a first associated value generated by the access point, and the first master key is also a function of the associated value. ! 3. The method of claim 1, wherein the key request message also includes at least one of an IP address (Internet Protocol) or a MAC address (Media Access Control) of an access point, and a first master session key also a function of the IP or MAC address. ! 4. The method of claim 1, wherein the received first master session key is also a function of an associated value generated or associated with an authentication device, and the access point receives an associated value from the authentication device. ! 5. The method according to claim 4, further comprising the step of:! send the associated value to the access terminal to allow the access terminal to generate the first master session key. ! 6
