摘要：Universal Mobile Telecommunications System is the third generation mobile communications system. It was built on the concepts of GSM and it is the starting point in the development of the fourth generation network. This paper proposes enhancements for the initial identification and for the Authentication and Key Agreement (AKA) protocols that solve two known vulnerabilities of UMTS security: identity catching and secret key exposure. It protects the messages exchanged during the Authentication and Key Agreement protocol. Considering the CDMA communications drawback, this paper proposes a two phased solution. The first phase of the solution consists of a secure key generation. The secure key generation phase is called AKA (Authentication and Key Agreement) -phase. The second phase of the solution is able to solve the problem of redirection attacks, man-in-the-middle attack, sequence number depletion attack, and roaming attack. This phase includes a User Confidentiality for UMTS (EMSUCU) protocol. This proposed solution is able to solve the problems, vulnerabilities through eliminating it and the solution is able to improve the security and efficiency. The enhanced SHAI technique proposed is able to solve redirection attacks, man-in-the-middle attack, sequence number depletion attack, and roaming attack.
