ID-based Authenticated Key Agreement for Low-Power Mobile Devices

In this paper we present an efficient ID-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. To achieve our goal we combine two notions, key agreement and IDbased authenticryption in which only designated verifier (or Sever) can verify the validity of a given transcript. We prove the security of our ID-based AKA protocols in the random oracle model.
