微电网是一种灵活的、本地化的电网，它可以与主电网断开连接，并独立运行在传统和/或可再生资源上。它还可以与主电网合作，甚至在主电网有过剩电力时向主电网供电，以帮助缓解能源压力。智能电能表对主网和微网之间的电能流动进行监测，实时记录终端用户的隐私信息和能源使用情况。因此，确保这些信息的隐私和安全是一个相当大的挑战。本文研究了微网和主网的关系，设计了一种基于雾计算的量子抵抗轻量级认证和密钥协商(AKA)协议。该协议提供双向认证，并在智能电表和雾节点之间生成会话密钥。更重要的是，它可以抵抗量子计算攻击，因为我们方案的安全性依赖于学习带噪声奇偶(LPN)问题的难度，这是一个NP-完全问题。最后，我们对我们提出的协议进行了性能评估，证明了我们的协议是更加轻量级和高效的。
A microgrid is a flexible and localized grid that can disconnect from the main grid and operate independently on the traditional and/or renewable resource. It also can work with the main grid, and even provide power to the main grid when it has excess power to help relieve the pressure of energy. The flow of power between main grid and microgrid is monitored by smart meter, which kept the end user’s privacy information and his/her energy usage in real time. Hence, ensuring the privacy and security of these information is a considerable challenge. In this paper, we investigate the relationship between microgrids and the main grid, and design a quantum-resistant lightweight authentication and key agreement (AKA) protocol based on fog computing. The proposed protocol provides the mutual authentication and generates a session key between a smart meter and a fog node. More importantly, it can resist against quantum computing attacks, as the security of our scheme relies on the hardness of the learning parity with noise (LPN) problem, an NP-complete problem. Finally, we evaluate the performance of our proposed protocol and prove that our protocol is more lightweight and efficient.
