Abstract: Aiming at the limitation of Wireless Sensor Network(WSN) in power, computation and storage, this paper presents a key management protocol based on Elliptic Curve Cryptosystem(ECC) for WSN. It gives the accomplished courses which consists of building communication key, adding new node, renewing and recycling key. The performance of security, resilience and efficiency are analyzed, experimental results indicate that the scalability and resilience of the protocol is much better.
