Efficient self-healing group key management protocol for wireless sensor networks
Xiangdong Wang · Jisuanji gongcheng yu sheji · 2013
A self-healing group key management protocol with revocation capability is proposed for the unreliable communication channel and higher packet loss rate in wireless sensor network.The safety of the group key is achieved by using one-way hash function and unknowable follow-up session key.The legitimate nodes can recover the lost group key through the redundancy associated with the history of the session key.The analysis of security and efficiency show that proposed protocol has lower communication cost and lower storage cost to ensure network security,so it is suitable for wireless sensor network.
