In this paper, we propose an efficient RSA public key encryption scheme, which is improved version of original RSA scheme. The proposed RSA encryption scheme is based on linear group over the ring of integer mod a composite modulus n which is the product of two distinct prime numbers. In the proposed scheme the original message and the encrypted message are h x h square matrices with entities in z...
Most of current authentication schemes for mobile systems have some weaknesses; such as leakage of UE identities and high update overhead of temporary identities. This paper proposes a secure authentication mechanism for mobile communication systems that satisfies the security requirements of the third generation mobile systems. In this proposed protocol, the number of messages between authentication...
