摘要: 提出一种在无线传感器网络中具有正确性验证和头结点撤销功能的组密钥更新方案. 通过建立组密钥之间的冗余关联,实现了在不增加结点负担的情况下,合法结点利用当前广播消息和自身秘密恢复丢失的组密钥. 利用撤销多项式实现对结点和头结点的撤销,此外还能提供密钥的正确性验证. 分析表明,在没有增加计算开销和通信开销情况下本方案具有更好的安全性.

Abstract: 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.

Key words: group key, selfhealing, node revocation, sensor network
