Chaotic Maps-Based Mutual Authentication and Key Agreement using Smart Cards for WirelessResearch Paper • April 8th, 2013
Abstract. Mobile users can roam into foreign networks and transmit messages to for- eign agents, and they can access the services provided by a foreign agent by using their mobile devices. Thus, mobile user authentication and key agreement for wireless commu- nications are becoming more and more important. In recent years, most of the existing user authentication and key-agreement protocols with smart cards for wireless commu- nications utilized modular exponential computing and scalar multiplication on elliptic curves to ensure their security. Inspired by the key-agreement protocols based on chaotic maps, we proposed a novel, chaotic maps-based authentication and key-agreement pro- tocol using smart cards for wireless communications. In our protocol, mobile users and foreign agents can authenticate each other and establish a common session key for further communications. Analysis of the security and functionality of our protocol showed that it can satisfy essential security and functi
