Revocation Self-healing Key Management Scheme in Wireless Sensor Network
Fuyou Miao · Jisuanji gongcheng · 2010
A revocation self-healing key management scheme in hierarchical Wireless Sensor Network(WSN) is proposed.The key updating,self-healing and the revocation function can be all achieved by only a single broadcast while the authentication mechanism is implemented.The analysis result shows that the scheme can reduce the cost of energy while guaranteeing the security and improves the security and the usability of WSN based on data aggregation.
