无线传感器网络对偶密钥误用检测算法

Algorithm for Misused Pairwise Keys Detection in Wireless Sensor Networks

无线传感器网络正常节点之间的对偶密钥有可能受损,攻击者将误用受损密钥伪造信息数据包,破坏正常通信或消耗节点有限的资源.针对这一问题,提出一种对偶密钥误用检测算法.在每一个信息数据包里附加一个可验证的认证因子,转发节点通过验证认证因子就能够确认对偶密钥是否被误用.通过安全分析和性能分析表明该检测算法的有效性.而且,该算法可集成到大多的密钥预分发算法或错误数据过滤算法,以提供更可靠的安全通信.

In wireless sensor networks, the pairwise keys shared by non-compromised nodes could be compromised, then the adversary would misuse the pairwise keys to forge message report in order to destroy secure communication or deplete the limited resource in sensor nodes. To address this issue, in this paper, an algorithm is proposed to detect misused pairwise keys. Specially, an efficient verifiable authenticator is attached to each message report. The forwarding node can detect whether the pairwise key is misused by verifying the authenticator. The security analysis and performance analysis demonstrate the efficiency of the proposed algorithm. Moreover, the proposed algorithm can be integrated with most of key pre-distribution schemes or false data filtering schemes to provide more reliable secure communication.
