A Key Management Scheme for Wireless Sensor Network
一种基于无线传感器网络的密钥管理方案

This paper proposes a key management scheme for wireless sensor network, which supports key establish- ment, re-keying and revocation of the key ring owned by a compromised sensor node via probabilistic negative polling of its neighbors. Furthermore, the related protocols or algorithms are very simple and no expensive public-key opera- tion is required in view of resource-starved sensor nodes, which minimizes the storage, computation, communication overhead and improves the efficiency of our scheme.
