ID-based Authenticated Key Agreement for Unbalanced Computing Environment
Kyu-Young Choi, Jung-Yeon Hwang, Hong Do-won, Donghoon Lee · Information Security and Cryptology · 2006
Key Agreement protocols are among the most basic and widely used cryptographic protocols. In this paper we present an efficient O-based authenticated key agreement (AKA) protocol by using bilinear maps, especially well suited to unbalanced computing environments : an ID-based AKA protocol for Server and Client. Particularly, considering low-power clients' devices, we remove expensive operations such as bilinear maps from a client side. Our protocol uses signcryption and provide security in random oracle model.
