针对实际应用中无线传感器网络的隐私保护需求和无线通信易出错的特点,提出一种可容错的安全聚集算法。算法通过多路径聚集保证在链路出现故障的情况下聚集可以正常进行,使用轻量级的同态加密系统,对传感器节点读数进行端到端的加密,保护数据隐私的同时允许基站解密获得最终聚合结果。仿真实验表明,算法具备较高的安全性和较好的容错能力,在计算和通信开销增加很小的情况下,能够获得准确的聚集结果。

This paper proposed a security aggregation algorithm with fault tolerant for wireless sensor networks which have high rates of communication failures and need privacy protection in practical applica-tions. The algorithm uses multipath-based routing paths for reliably carrying out aggregation in sensor net-works exhibiting link failures, and uses a lightweight homomorphic cryptosystem for maintaining the end-to-end confidentiality of individual sensor readings, so the privacy-preserving can be achieved while allo-wing the sink node to decrypt the hidden aggregate value. Simulation results show that the algorithm a-chieves a high degree of security and fault tolerant, the accurate aggregate result can be obtained with im-posing small computation and communication overhead.
