Cryptanalysis of Aydos et al.´s ECC-based wireless authentication protocol

With the rapid development of communication technology, wireless technology has become more and more important, and has been widely used in personal communication. Recently, Aydos et al. proposed an ECC-based authenticated key agreement protocol for wireless communication. In their protocol, they used ECDSA and Diffie-Hellman key agreement to provide authentication and to obtain a session key for later communication. In this paper, however, we show that Aydos et al´s ECC-based authenticated key agreement protocol for wireless communication does not achieve some essential security requirements including forward secrecy, known-key security, and mutual authentication.
