摘要: 低功耗广域网技术以功耗低、距离远等优势,已成为当前的一个研究热点。但是,由于低功耗广域网中传感器节点安全防护能力有限、容易老化以及存在恶意节点等问题,导致系统在效率和私密性方面并不是完全可靠。针对上述问题,本文为无线电广域网的媒体介入控制层设计一套密文数据审计算法。通过使用布隆过滤器,加快密文数据处理的效率。此外使用同态加密技术,在保护数据的前提下,实现有效密文数据范围查询功能。最后利用区块链技术实现对通讯数据的溯源,方便日后对问题节点进行追踪。分析结果显示,新方案具有较高的安全性能,并且运行效率能够达到O(logn)。

Abstract: Low-power wide area network has the advantages of low power consumption and long distance, which has become a research hotspot. However, the system is not completely reliable in terms of efficiency and privacy due to the limited security capability of sensor nodes, easy aging and malicious nodes in low-power wide area network. Aiming at the above problems, this paper analyzes Lora’s media access control layer and proposes a set of ciphertext data audit algorithm. The efficiency of ciphertext data processing is accelerated by Bloom filter. In addition, the homomorphic encryption technology is used to realize effective ciphertext data range query function on the premise of data protection. Finally, the Blockchain technology is used to realize the traceability of communication data, so as to facilitate the follow-up of problem nodes. The analysis results show that the new scheme has high security performance and the communication efficiency can reach O(logn).
