摘要
该文提出了一种基于检查点的多跳确认方案来检测选择传递攻击所导致的异常丢包.在这个方案中,能够随机地选取传递路径中的部分节点为检查点,负责包的确认.这种随机检查点选择技术能够避免部分节点成为敌方俘获的目标,从而在保证检测能力的同时有效地提高了系统的健壮性.文章对检测率进行了理论分析,并进一步通过模拟实验对检测率进行了验证.
In this paper, the authors propose a lightweight security scheme, CHEMAS(CHEck- point-based Multi-hop Acknowledgement Scheme), for detecting selective forwarding attacks. This scheme can randomly select part of intermediate nodes along a forwarding path as checkpoint nodes which are responsible for generating acknowledgements for each packet received. The strategy of random checkpoint selection significantly increases the resilience against attacks because it prevents a proportion of the sensor nodes from becoming the targets of attempts to compromise them. The authors examine the detection accuracy of this scheme using both theoretical analysis and simulations.
