ON SELF-HEALING GROUP KEY DISTRIBUTION SCHEME BASED ON TIME-LIMITED REVOCATION FOR MOBILE Ad hoc NETWORKS
摘要
Abstract
A novel group key distribution scheme with self-healing capability based on time-limited revocation for MANET (mobile ad hoc network) is proposed. The control of group key in access and redundant association relation between different group keys is realised using DDHC ( dual directional hash chains ) and HBT ( Hash binary tree) ; By means of session key information and keys' secrets information itself currently distributing, the legal group members can recover the lost historical group keys without the help of the group manager, and the revocation function of the group manager can be achieved by revoking the polynomial secretly. Moreover, an improved scheme is proposed as well. The security and performance analysis shows, this proposed scheme are secure in resisting the collusive breaking attacks launched by multiple group members; on premise of satisfying the security requirements of MANET, it saves effectively the storage resources and networks bandwidth.关键词
