Providing a suitable authenticated key establishment protocol in wireless and mobile networks is challenging due to all the characteristics of these networks, such as communication capability, computation capability and storage resources. This paper presents an efficient and flexible authenticated key agreement protocol without bilinear pairings for wireless and mobile networks. The authors proposed protocol not only provides mutual authentication between users and servers but also supports session key agreement. In addition, in their protocol the user does not need to perform the expansive bilinear operations, so it reduces the computation loads. Compared with the related works, the proposed scheme is more efficient and practical.
