Remarks on unknown key-share attack on authenticated multiple-key agreement protocol
Hong-Sheng Zhou, Lei Fan, Jianhua Li · Electronics Letters · 2003
Recently Shim gave an attack on Harn's modified authenticated multiple-key agreement protocol. The authors point out Shim's attack is not workable. However, Harn's modified protocol is still insecure and the authors give another attack on it. Finally, the authors propose an efficient protocol that can prevent this attack.
