EPMOS based secure mobile communication in LTE/SAE networks

PKI (Public Key Infrastructure) based AKA (Authentication and Key Agreement) scheme known as Optimizing PKI for 3GPP Authentication and Key Agreement(OPAKA) has been proposed in the field of 3G wireless mobile communication system. The study of OPAKA revealed the drawback of protocol and an Enhanced version of OPAKA namely EPMOS (Enhancing PKI for Mobile Commerce Security) is proposed. The recent expansion of wireless technologies and 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). The realisation of better bandwidth, full interworking with other access/backend systems using all-IP architecture with well-defined interworking with circuit switched system becoming reality. 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. The EPMOS can used to solve the vulnerabilities in LTE.
