A smart grid (SG) is an advanced power grid system deployed in a cloud center and smart meters (at the consumer end) that provides higher reliability, better data protection, improved power efficiency, automatic monitoring, and effective management of power consumption. However, an SG also poses certain challenges that need to be addressed. For example, data provided by a smart meter are time-sensitive and cannot handle high latency in an SG. Moreover, a smart meter depends on memory, energy, and other factors. Besides, the security between a cloud center and a smart meter is a critical issue that needs to be resolved. Edge computing, an extension of cloud computing deployed in an edge network between a cloud center and the end devices, is an efficient solution to the aforementioned issues. Therefore, in this study, we propose a secure mutual authentication protocol based on edge computing for use in an SG.

智能电网（SG）是部署在云中心和智能电表（位于用户端）的高级电网系统，可提供更高的可靠性，更好的数据保护，更高的电源效率，自动监控和有效的功耗管理。但是，研究组还提出了一些需要解决的挑战。例如，智能仪表提供的数据对时间敏感，并且无法处理SG中的高延迟。此外，智能电表取决于内存，能源和其他因素。此外，云中心和智能电表之间的安全性是需要解决的关键问题。边缘计算是部署在云中心和终端设备之间的边缘网络中的云计算的扩展，是对上述问题的有效解决方案。因此，在这项研究中
