On the Feasibility of Key Compromise Impersonation Attacks Against the Elliptic Curve Version of the MTI/C0 Key Agreement Protocol
Keywords:
Key agreement protocols, elliptic curves, key-compromise impersonation.Abstract
—In a recent conference (ICSSSM 2010), Eun-Jun Yooni and Kee-Young proposed the two-pass elliptic curve Diffie-Hellman key agreement protocol EECKE-1N that according to the authors is more efficient that ECKE-1N. In this paper we point out that the protocol proposed by the aforementioned authors is in fact the elliptic curve version of the MTI/C0 family of key agreement protocols which suffer from a well-known vulnerability against a particular type of key-compromise impersonation attack.
