Abstract:Mobile users can roam into foreign networks and transmit messages to foreign 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 communications are becoming more and more important. In recent years, most of the existing user authentication and key-agreement protocols with smart cards for wireless communications 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 protocol 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 functionality requirements. In addition, performance analysis showed that our protocol can refrain from consuming modular exponential operation and scalar multiplication on elliptic curves. The computational cost of the proposed protocol compares favorably with the cost of related protocols. ? 2013.
