Patent attributes
Systems and methods for providing authentication key agreement (AKA) with perfect forward secrecy (PFS) are disclosed. In one embodiment, a network according to the disclosure may receive an attach request from a UE, provide an authentication request including a network support indicator to a network resource, receive an authentication token from the network resource, such that the authentication token includes an indication that a network supports PFS, provide the authentication token to the UE, receive an authentication response including a UE public key value, obtain a network public key value and a network private key value, determine a shared key value based on the network private key value and the UE public key value, bind the shared key value with a session key value to create a bound shared key value, and use the bound shared key value to protect subsequent network traffic.
