Anti-collusive Self-healing Key Distribution Scheme with Revocation Capability

ChunLai Du, MingZeng Hu, HongLi Zhang and WeiZhe Zhang

Abstract:
This study proposes an anti-collusive self-healing group key distribution scheme with revocation using dual directional hash chain. The session key is computed from three parts: forward key, backward key and random session number. The former two parts are built on dual directional hash chain. Users are provided with a set of private secrets according to their legal lifetimes. In terms of communication cost, the proposed scheme is more efficient than the previous schemes not based on one-way hash chain and is slightly increased compared with the previous scheme based on one-way hash chain. According to the security analysis results, the proposed scheme can resist the collusion of revoked users and newly joined users.
