摘要: Recently, Shim proposed a tripartite authenticated key agreement protocol from Weil pairing to overcome the security flaw in Joux’s protocol. Later, also an ID-based which is improvement of Smart’s order provide forward secrecy. In this paper, we show that these two protocols are insecure against key-compromise impersonation attack and manin-the-middle respectively.
