A Secure Key Agreement Protocol using Elliptic Curves

Abstract

The author proposes a secure protocol for authenticated key agreement based on Diffie-Hellman key agreement, which works in an elliptic curve group. The article also presents a simpler authenticated key agreement protocol than the proposed one and a multiple key agreement protocol that enables participants to share two or more keys in one execution of the protocol. The protocols are shown to meet the security attributes under the assumption that the elliptic curve discrete logarithm problem is secure.
