Cryptanalysis of authenticated multiple keys exchange protocol based on bilinear pairings
Eun‐Jun Yoon, Kee-Young Yoo · 2011
In 2010, Lee-Chen proposed an authenticated multiple keys exchange protocol based on bilinear pairings. Lee-Chen claimed that their proposed protocol not only is secure to a forgery attack, but also provides perfect forward secrecy. However, this paper points out that Lee-Chen's protocol is still insecure to a forgery attack and cannot provide perfect forward secrecy.
