摘要：In this paper, we propose a secure authentication of the Evolved Packet System Authenticationand Key Agreement (EPS-AKA) for the LTE-A network. Our scheme is proposed to solve theproblem of sending the IMSI as a clear text, and hence prevents the mobility management entityattack. We will use public key (PK) cryptography to protect the transmitted messages, the RSAscheme computation to compute a temporary value to the IMSI, and nonce to generatechallenge messages toward the opposite side. Our scheme does not need to change the originalframework and the infrastructure of the LTE-A network, although a ciphered IMSI istransmitted. The authentication procedure is performed by the HSS to authenticate the UEs andthe MME; therefore, the impersonating of the MME and UEs is not possible. Our evaluationdemonstrates that the proposed scheme is secure and achieves the security requirements of theLTE-A subscribers such as privacy, authentication, confidentiality and integrity. In our scheme,we try to maintain the problems defined in the previous related works.
