Smart power grid is a two-way interconnected network in which information plays a fundamental role in the process of energy transmission and distribution. The smart grid is based on combining ICT with the processing capabilities of computers and electrical systems to increase communication between users. However, smart grids are exposed to a variety of malicious cyber-attacks that can lead to the destruction of basic infrastructure and disrupt communication between the grid and users. Meanwhile, by authenticating the authenticated users, cyber-security can be created in the smart grid. One of the main components of a smart power grid is smart meters. However, to maintain security in a communication, smart meter authentication alone is not enough and it must be ensured that the electricity company’s server is not forgery. Therefore, there is a need for two-way authentication between the smart meter on the home side and the electricity company server. The present work provides a key management layout (based on the elliptic curve cryptography) with two-way authentication for communication outside the home area network The proposed solution is two-way authentication among the smart meter and the security associate in the power company. In other words, the proposed methodology creates a solution to establish a connection between valid users and the smart grid. The proposed protocol evaluates the behavior of cyber-attacks on the smart grid. Attacks such as man-in the middle attacks and retransmission attacks are considered. It was found that, the proposed methodology improves the reliance between smart grid and authenticated users with the increase of secure communications. Moreover, the proposed protocol can prevent an extensive experiment attack. The results also showed that, as the false factor increases, the detection time by the proposed algorithm increases. As the false factor increases from 0.1 to 0.3, the detection time increases by 1.4 s.

确保智能电网和真实用户之间的通信安全；提供基于用户身份验证的方法

智能电网是双向互联的网络，信息在能源传输和分配过程中发挥着基础性作用。智能电网将信息通信技术与计算机和电气系统的处理能力相结合，以增加用户之间的通信。然而，智能电网面临各种恶意网络攻击，这些攻击可能导致基础设施遭到破坏，并扰乱电网与用户之间的通信。同时，通过对经过身份验证的用户进行身份验证，可以在智能电网中创建网络安全。智能电网的主要组成部分之一是智能电表。然而，为了维护通信的安全性，仅靠智能电表认证是不够的，必须确保电力公司的服务器不被伪造。因此，家庭侧智能电表和电力公司服务器之间需要进行双向认证。目前的工作提供了一种具有双向身份验证的密钥管理布局（基于椭圆曲线密码学），用于家庭区域网络之外的通信。所提出的解决方案是智能电表和电力公司安全助理之间的双向身份验证。换句话说，所提出的方法创建了一个在有​​效用户和智能电网之间建立连接的解决方案。拟议的协议评估智能电网上的网络攻击行为。考虑中间人攻击和重传攻击等攻击。研究发现，随着安全通信的增加，所提出的方法提高了智能电网和经过身份验证的用户之间的依赖。此外，所提出的协议可以防止广泛的实验攻击。结果还表明，随着错误因素的增加，所提出算法的检测时间也会增加。随着错误因子从 0.1 增加到 0.3，检测时间增加 1.4 s。
