A Secure and Efficient Key Exchange Protocol for Mobile Communications

Fuw-Yi Yang and Jinn-Ke Jan

Abstract: This paper proposes a key exchange protocol with mutual authentication, which requires only 0.1 modular multiplications for online computations. This online computation is ten times faster than that of conventional protocols. The message size of the proposed protocol is about half (50%~66%) that of the previous protocols. In addition to its efficiency in online computation and bandwidth, the paper provides a formal proof to guarantee the security of the proposed protocol. Possessing of both secure and efficient properties makes the proposed protocol suitable for the low power mobile communications.
