Abstract


In order to solve the security problems in the existing self-healing group key distribution strategies, this paper proposes a new mutual healing group key distribution scheme. Based on the access polynomials, this scheme can hide the keys by using hash function and enable the communication group nodes to restore the lost session keys through the use of broadcasting messages and private keys. Besides, this scheme can restore the key of the last time with the help of neighbor nodes, which is impossible for the self-healing key distribution scheme. Analytical results show that the proposed scheme can guarantee the forward and backward security and resist the collusion attack, which is suitable for WSN.
