On the security of the ECKE-1N and EECKE-1N elliptic-curve key agreement protocols

摘要

In a recent paper published in the proceedings of the EBISS'09 conference, Mohammad and Chi-Chun Lo claim that protocol ECKE-1N is vulnerable to key compromise impersonation (KCI) attacks and ephemeral key leakage. They also present protocol EECKE-1N, a revised version of protocol ECKE-1N, which is supposedly more secure since it does not exhibit similar vulnerabilities.
