A Secure Key Agreement Protocol using Elliptic Curves
C. Popescu · International Journal of Computers and Applications · 2005
In this paper we propose a secure protocol for authenticated key agreement based on Diffie-Hellman key agreement, which works in an elliptic curve group. We also present a simpler authenticated key agreement protocol than the proposed one and a multiple key agreement protocol which enables the participants to share two or more keys in one execution of the protocol. We prove that our protocols meet the security attributes under the assumption that the elliptic curve discrete logarithm problem is secure. Key Words: Protocols, authenticated key agreement, elliptic curves. 1.
