A Consensus Algorithm Based Identity Authentication Mechanism for Secure Access of Wireless Sensor Networks in Converter Stations

为了确保换流站无线传感网的安全性和可靠性,文章在换流站无线传感网中构建安全接入身份认证机制,提出了一种基于加权投票的共识算法,对接入换流站无线传感网的无线感知设备进行身份认证和授权,确保接入设备对无线传感网络资源的访问合法性。所提出的共识算法采用了加权投票的思想,根据感知设备拥有的资源和性能2个方面综合考虑并决定权重,通过权重值衡量节点在共识过程中的影响力,从而提高共识过程的公正性和可信度,并有效避免网络中的恶意攻击行为。从平均耗时、吞吐量、出错率和通信量开销等方面进行仿真验证,结果表明所提算法能够更好地适应不同接入终端之间的差异,提高了共识算法的效率和可靠性,为换流站无线传感网提供了有效的安全保障。

In order to ensure the security and reliability of the wireless sensor network of the converter station,this paper constructs a secure access authentication mechanism in the wireless sensor network of the converter station,and proposes a consensus algorithm based on weighted voting to authenticate and authorize the wireless sensing devices that access the wireless sensor network of the converter station and ensure the legitimacy of the access devices'access to the wireless sensor network resources.The consensus algorithm proposed in this paper adopts the idea of weighted voting to consider and decide the weight based on both the resources and performance owned by the sensing devices,and measure the influence of nodes in the consensus process by the weight value,so as to improve the fairness and trustworthiness of the consensus process and effectively avoid malicious attacks in the network.In this paper,the simulation verification is carried out from the aspects of average time consumption,throughput,error rate and communication overhead.The results show that the proposed algorithm can better adapt to the differences between different access terminals,improve the efficiency and reliability of the consensus algorithm,and provide effective security guarantee for the wireless sensor network of the converter station.
