This paper describes the security features incorporated into the third generation (3G) mobile system developed in 3GPP, specifically the enhancements to the shared secret symmetric authentication scheme as used in GSM. The proposed security architecture for the Internet multimedia subsystem (IMS) based on and built upon Internet applications, services and protocols, is then described. Finally, the paper describes some early work by 3GPP to integrate public key security mechanisms into 3G, while maintaining the global reach and call set-up performance, that mobile users now take for granted.
