In order to support randomly moving users,a THC(two-hop cover) algorithm and a two-hop cover-based ac-cess control scheme were proposed.The proposed algorithm made two-hop nodes be able to retrieve access control in-formation of user’s in time through diffusing the information periodically.The scheme based on THC algorithm,the se-curity mechanisms of Merkle hash tree and one way chain,as well as distributed access control mode,its main contribu-tion was it supports randomly moving users for the first time.The analyses and experiments have shown that the pro-posed scheme can be applied to both mobile and stationary user and have several advantages over the current access con-trol methods of low cost in computation,communication and storage,and resistance to node capture,query replay and DoS attacks. |
