Abstract

In this paper the main focus is to establish a set of security features, methodologies and mechanisms to build the Network Access Security Management (NASM) architecture which provides users a secure access to next generation mobile telecommunication network services. The NASM architecture involves the authentication and key agreement, security mode setup during connection establishment, and access link data integrity and confidentiality between mobile user and universal mobile telecommunication systems. The NASM framework also provides measures to enhance the security weaknesses of GSM security framework and protect the users against attacks on the radio access link of Universal Mobile Telecommunication Systems (UMTS) based on 3GPP technical specifications [1]. The NASM model is part of Secure Service Provisioning Framework (SSPF) [2] for IP Multimedia System (IMS) and Next Generation Networks (NGN) of Third Generation and beyond (3Gb) Testbed [9] and IP Multimedia System (IMS) Playground [10] which provide R& D infrastructure at Fokus Fraunhofer.
