Wireless Sensor Networks (WSNs) are becoming more popular for many applications due to their convenient services. However, sensor nodes may suffer from significant security flaws, leading researchers to propose authentication schemes to protect WSNs. Although these authentication protocols significantly fulfill the required protection, security enhancement with less energy consumption is essential to preserve the availability of resources and secure better performance. In 2020, Youssef et al. suggested a scheme called Enhanced Probabilistic Cluster Head Selection (LEACH-PRO) to extend the sensors' lifetime in WSNs. This paper introduces a new variant of the LEACH-PRO protocol by adopting the blockchain security technique to protect WSNs. The proposed protocol (SLEACH-PRO) performs a decentralized authentication mechanism by applying a blockchain to multiple base stations to avoid system and performance degradation in the event of a station failure. The security analysis of the SLEACH-PRO is performed using Burrows-Abadi-Needham (BAN) logic and Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. Moreover, the SLEACH-PRO is evaluated and compared to related protocols in terms of computational cost and security level based on its resistance against several attacks. The comparison results showed that the SLEACH-PRO protocol is more secure and requires less computational cost compared to other related protocols.
无线传感器网络(WSNs)由于其便捷的服务而在许多应用中越来越受欢迎。然而,传感器节点可能存在严重的安全缺陷,这促使研究人员提出认证方案来保护 WSNs。虽然这些认证协议显著满足了所需的保护,但提高安全性同时减少能源消耗对于保护资源的可用性和实现更好的性能至关重要。2020 年,Youssef 等人提出了一种名为 Enhanced Probabilistic Cluster Head Selection(LEACH-PRO)的方案,旨在延长 WSNs 中的传感器寿命。本文通过采用区块链安全技术来保护 WSNs,提出了 LEACH-PRO 协议的一种新变体。所提出的协议(SLEACH-PRO)通过将区块链应用于多个基站来执行分散式认证机制,以避免在基站发生故障时系统和性能降级。使用 Burrows-Abadi-Needham(BAN)逻辑和 Automated Validation of Internet Security Protocols and Applications(AVISPA)工具对 SLEACH-PRO 的安全性进行了分析。此外,根据其对几种攻击的抵抗能力,从计算成本和安全级别方面对 SLEACH-PRO 进行了评估和与相关协议进行了比较。比较结果表明,与其他相关协议相比,SLEACH-PRO 协议更安全,所需的计算成本更低。
