A Group Key Distribution Scheme with Verification and Revocation

A group key distribution scheme with revocation capability was proposed for wireless sensor network.By using the broadcast information and its own secrets,the legal nodes which lost some session keys can recover them through the association between different session keys,without requiring additional transmission from the group manager.The group manager can revoke the group nodes and the group header by revocation polynomial.From the security and efficiency analysis,this key distribution scheme can achevie better security without needing more communication or storage cost.
