In wireless sensor networks, the adversary can easily control the compromised nodes to inject false data reports. En-route filtering is an effective mechanism to resist such attacks, where the forwarding nodes of the reports can identify and drop the false reports. However, the existing en-route filtering strategies are vulnerable to report disruption attacks and selective forwarding attacks, and the probabilities and efficiencies of en-route filtering false reports are low. To address these problems, a precheck mechanism performed by the CoS (Center-of-Stimulus) node is presented to resist report disruption attacks, a report forwarding strategy with balancing the residual energy of the nodes is designed to resist selective forwarding attacks, and an en-route message authentication scheme (EMAS) based on monitoring and reporting mechanism is proposed to resist false data injection attacks. The theoretical analysis and simulation results show that in most cases, EMAS provides a higher security level and higher en-route filtering probability and efficiency and is very efficient in energy saving.

用于过滤 WSN 中虚假数据的路由消息认证方案

在无线传感器网络中，攻击者可以轻松控制受感染节点注入虚假数据报告。路由过滤是抵御此类攻击的有效机制，报告的转发节点可以识别并丢弃虚假报告。然而，现有的中途过滤策略容易受到报告中断攻击和选择性转发攻击，并且中途过滤虚假报告的概率和效率较低。针对这些问题，提出了一种由CoS（Center-of-Stimulus）节点执行的预检机制来抵御报告中断攻击，设计了一种平衡节点剩余能量的报告转发策略来抵御选择性转发攻击，并提出了一种基于监控和​​报告机制的航路消息认证方案（EMAS）来抵抗虚假数据注入攻击。理论分析和仿真结果表明，在大多数情况下，EMAS提供了更高的安全级别和更高的航路过滤概率和效率，在节能方面非常有效。
