With advances in technology, a mobile device today is like a mini PC that provides voice and data services in the form of smart-phones. Phenomenal increase in data services which enable mobile communication access to critical aspects of human society/life has led to standardization of SAE/LTE (System Architecture Evolution/Long Term Evolution) by 3GPP and IEEE 802.16e/WiMAX. SAE/LTE is also known as Evolved Packet System (EPS). This book addresses the newer security issues that have arisen as a result of penetration of mobile communications and standardization. In particular, the book focuses on the latest security developments in 3GPP SAE/LTE and WiMAX. The intended audience for this book are mobile network and device architects, designers, researchers and students. The goal of the authors, who have a combined experience of more than 25 years in mobile security standardization, architecture, research, and education, is to provide the book's readers with up-to-date information about the architecture and challenges of EPS and WiMAX security. The book has six chapters; the first three chapters are intended to be introductory ones, and the remaining three chapters provide an in-depth assessment of security provisions. Chapter 1 provides a background to the Next Generation Mobile Networks (NGMN) activity and requirements. Chapter 2 provides an overview of security, telecommunication systems and their requirements. Chapter 3 provides some background information on standardization. Chapter 4 discusses the EPS (or SAE/LTE) security architecture developed by 3GPP, in particular, the authentication and key agreement method for SAE/LTE together with newly defined key hierarchy. This chapter also addresses the challenging aspects of SAE/LTE interworking and mobility with UMTS together with the necessary key-exchange technologies. The focus of Chapter 5 is WiMAX (IEEE 802.16) security and provides an in-depth discussion of the WiMAX security requirements, the authentication aspects of PKMv2, and the overall WiMAX network security aspects. Chapter 6 briefly covers security for (i) Home(evolved)NodeB [H(e)NB is the Femto solution from 3GPP], (ii) Machine-to-Machine (M2M) security and (iii) Multimedia Broadcast and Multicast Service (MBMS) and Group Key Management.As such IMEI should be unique for each UE but in reality there are several cases of reuse of IMEI by manufacturers. The IMEI is composed of(1) the type allocation code (TAC) of 8 digits, which is allocated by a central body to all manufacturers;anbsp;...
