Authentication and Key Agreement in 3GPP Networks
Krishna Prakash · 2015
The huge demand for mobile communications with broad band and usage of new wireless applications motivated the development of new wireless access technologies.The recent expansion of wireless technologies, novel applications and the advancement in mobile technology after UMTS-3G has been taken up to the next level by the 3GPP Long Tem Evolution/System Architecture Evolution (LTE/SAE).It has achieved the realisation of better bandwidth, full interworking with other access/backend systems using all-IP architecture with well-defined interworking with circuit switched system.The system is defined to work across multiple access networks (3GPP and non 3GPP) may be trusted or non-trusted.The security mechanism in wireless area has evolved from original analog systems through GSM and UMTS.The GSM has focussed the security for radio path whereas UMTS has enhanced it in to network functionalities.The future networks based on IP mechanism demands more security features, since the threats related to IP are also possible.
