A Provable Secure Key Management Program for Wireless Sensor Network

This paper presents a new authentication and key agreement protocol EMSR for wireless sensor network. The program can achieve mutual authentication and establish a shared session key between nodes by using public key certificate. Meanwhile, it effectively prevents the authentication problems due to the usage of purely symmetric encryption mechanism, and it has small communication cost, fast calculation and supporting low consumption sensor network nodes. In addition, we give the security proof of this new protocol EMSR with CK security model, which indicates that EMSR has the corresponding security attributes of CK security model, and therefore it satisfies the requirements of sensor network.
