Security for IP multimedia services in the 3GPP third generation mobile system

Abstract

This paper surveys the security architecture of the IP multimedia core network subsystem (IMS) of the third generation mobile system which is known in Europe as UMTS. The main features of the security architecture include user specific features protecting the access of the IMS user, such as authentication and key agreement when a user registers and integrity protection of IMS access signalling, but also features for the user, independent protection of SIP signalling in the IMS core network. Authenticated registration is given an in‐depth treatment.
