Junghyun Nam · 2007
1 Introduction The highest priority in designing a key exchange protocol is placed on ensuring the security of session keys to be established by the protocol. Roughly speaking, establishing a session key securely means that the key is being known only to the intended parties at the end of the protocol run. Even if it is computationally infeasible to break the cryptographic algorithms used, the whole system becomes vulnerable to all
