Abstract: Random number and broadcast polynomial for every session were created. The legal nodes could recover the lost legal group keys by themselves independently according to their private information and broadcast messages, and the collusion attack between newly joined nodes and revoked nodes was resisted. New private information was distributed to revoked nodes so as to rejoin group in later sessions. Through the security and efficiency analysis, the scheme has less communication cost yet still achieves security property, suitable for mobile Ad Hoc network.
Key words: group key management, self-healing, collusion attack, mobile Ad Hoc network
摘要: 通过为每个会话时段产生随机数和构造广播多项式,使得合法用户根据自身秘密信息和当前广播消息,可以独立地恢复遗失的组密钥,而且能够抵抗被撤销节点和新加入节点的合谋攻击;此外,赋予被撤销节点新的秘密信息,使其能够重新加入群组参与会话。安全分析和性能分析表明:在保证安全属性的前提下,该方案具有较小的通信开销,能够适用于移动自组网。
