<b>Efficient identity-based authenticated multiple key exchange protocol</b> - doi: 10.4025/actascitechnol.v35i4.16434

Abstract

Authenticated multiple key exchange (AMKE) protocols not only allow participants to warrant multiple session keys within one run of the protocol but also ensure the authenticity of the other party. Many AMKE protocols using bilinear pairings have been proposed. However, the relative computation cost of the pairing is approximately twenty times higher than that of the scalar multiplication over elliptic curve group. In order to improve the performance, an ID-based AMKE protocol without bilinear pairing is proposed. Since the running time is largely saved, suggested protocol is more practical than the previous related protocols for practical applications.
