Smart grids integrate information and communications technology into the processes of electricity production, transportation, and consumption, thereby enabling interactions between power suppliers and consumers to increase the efficiency of the power grid. To achieve this, smart meters (SMs) are installed in households or buildings to measure electricity usage and allow power suppliers or consumers to monitor and manage it in real time. However, SMs require a secure service to address malicious attacks during memory protection and communication processes and a lightweight communication protocol suitable for devices with computational and communication constraints. This paper proposes an authentication protocol based on a one-way hash function to address these issues. This protocol includes message authentication functions to address message tampering and uses a changing encryption key for secure communication during each transmission. The security and performance analysis of this protocol shows that it can address existing attacks and provides 105,281.67% better computational efficiency than previous methods.
智能电网将信息和通信技术集成到电力生产、传输和消费过程中，从而使电力供应商和消费者之间能够进行交互，以提高电网效率。为此，家庭或建筑物中安装了智能电表（SM）来测量用电量，并允许电力供应商或消费者实时监测和管理用电情况。然而，智能电表需要安全服务来应对内存保护和通信过程中的恶意攻击，以及一种适用于具有计算和通信限制设备的轻量级通信协议。本文提出了一种基于单向哈希函数的认证协议来解决这些问题。该协议包括用于应对消息篡改的消息认证功能，并在每次传输期间使用变化的加密密钥进行安全通信。该协议的安全性和性能分析表明，它可以应对现有攻击，并且计算效率比以前的方法提高了105281.67%。
