This paper considers how two parties communicate securely over an adversary-controlled network. We especially focus on the problem of ID protection because of the recently rapid development of mobile network where any transferred message is easily eavesdropped on. We analyze several existing key exchange protocols and point out their problems: e.g. incompleteness of ID protection and vulnerability to DoS attacks. Then we model the notion of ID protection and construct a protocol with provable security. Key-words: Key-exchange protocol, SK-security, ID protection, One-time ID, DoS attacks.
