A New Efficient ID-Based Authenticated Key Agreement Protocol

Quan Yuan and Songping Li

Abstract: Recently Eun-Kyung Ryu, Eun-Jun Yoon, and Kee-Young Yoo proposed an efficient ID-based authenticated key agreement with paring.They argued that it is secure and efficient. In this paper, we show this protocol is doesn't satisfy the Key-Compromise Impersonate property and it is not secure against key reveal attack. Then we propose our protocol from this protocol and shim's protocol, its security and efficiency was analyzed.
