%X The conventional dual directional hash chains based self-healing group key distribution schemes are vulnerable to the collusion attack. To overcome the problem, this paper introduced EDDHC, which consisted of a slide window and a light weight sub-chain LiBHC. The paper also used EDDHC to design the group key distribution scheme. The proposed scheme enabled the seamless switching of the group key in used and the greater reduction of security vulnerability to the collusion attack. The analysis illustrates that the scheme maintains low resource overhead while achieving better reliability and security performance.
