An Efficient Self-healing Group Key Management with Lower Storage for Wireless Sensor Network

For the problems of energy constrained and the channel insecurity in group communication of WSN, we propose a self-healing group key management protocol based on polynomial and some algorithm. This protocol can recover the lost group key without transmitting message once more. The method can improve the security of the channel, while consuming less energy. The performance analysis of this protocol shows that we can achieve forward secrecy and backward secrecy and communication security with lower energy consumption, which can expand the range of applications of wireless sensor networks while improving life.
