智能电网已被公认为优化能源效率的下一代智能电网。主要通过双向通信渠道，供应商和用户可以实时动态调整电力传输。然而，随着智能电网的广泛部署，出现了许多安全问题，例如集中式注册机构和潜在的分布式拒绝服务(DDoS)攻击。这些存在的问题威胁着智能电网的可用性。本文主要针对智能电网中存在的一些身份认证问题进行了研究。结合区块链、椭圆曲线密码体制、动态加入退出机制和批量验证技术，提出了一种可靠高效的智能电表和公用事业中心认证协议。同时，通过计算难问题假设，保证了协议的可证明安全性。实验结果表明，与其他椭圆曲线密码体制相关方案相比，该协议在安全性和性能上都有所提高。
Smart grid has been acknowledged as the next-generation intelligent network that optimizes energy efficiency. Primarily through a bidirectional communication channel, suppliers and users can dynamically adjust power transmission in real time. Nonetheless, many security issues occur with the widespread deployment of smart grid, e.g., centralized register authority and potential Distributed-Denial-of-Service (DDoS) attack. These existing problems threaten the availability of smart grid. In this paper, we mainly focus on solving some identity authentication issues remained in the smart grid. Combined with blockchain, Elliptic Curve Cryptography (ECC), dynamic Join-and-Exit mechanism and batch verification, a reliable and efficient authentication protocol is proposed for smart meters and utility centers. Simultaneously, the provable security of this protocol is assured by the computational hard problem assumptions. Experiment results show that our protocol has achieved security and performance improvement compared with the other ECC related schemes.
