Abstract

We propose an authentication and key agreement protocol for wireless communication based on elliptic curve cryptographic techniques. The proposed protocol requires significantly less bandwidth than the Aziz-Diffie and Beller-Chang-Yacobi protocols, and furthermore, it has lower computational burden and storage requirements on the user side. The use of elliptic curve cryptographic techniques provide greater security using fewer bits, resulting in a protocol which requires low computational overhead, and thus, making it suitable for wireless and mobile communication systems, including smartcards and handheld devices.
