Authentication Mechanism for 5G Technologies

摘要

Embodiment mutual authentication and security agreement (MASA) protocols may use independently generated integrity and/or encryption keys to securely communicate private information exchanged between UEs and various network-side devices (e.g., base stations, MMEs, HSSs, etc.). In particular, embodiment MASA protocols may use an initial authentication request (IAR) encryption key (KIAR_ENC) to encrypt UE specific information (e.g., an IMSI, etc.) in an IAR message and/or an initial authentication response (IAS) encryption key (KIAS_ENC) to encrypt private information in an IAS message. Additionally, embodiment MASA protocols may use an IAR integrity protection key (KIAR_INT) to verify the integrity of information in an IAR message and/or an IAS integrity protection key (KIAS_INT) to verify the integrity of information in an IAS message. The KIAR_ENC, KIAR_INT, KIAS_ENC, and/or KIAS_INT may be independently computed by the UE and a home subscriber server (HSS).
