Smart Grid Communication Under Elliptic Curve Cryptography

Smart Grids (SGs) are introduced as a solution for standard power distribution. The significant capabilities of smart grids help to monitor consumer behaviors and power systems. However, the delay-sensitive network faces numerous challenges in which security and privacy gain more attention. Threats to transmitted messages, control over smart grid information and user privacy are the major concerns in smart grid security. Providing secure communication between the service provider and the user is the only possible solution for these security issues. So, this research work presents an efficient mutual authentication and key agreement protocol for smart grid communication using elliptic curve cryptography which is robust against security threats. A trust authority module is introduced in the security model apart from the user and service provider for authentication. The proposed approach performance is verified based on different security features, communication costs, and computation costs. The comparative analysis of experimental results demonstrates that the proposed authentication model attains better performance than existing state of art of techniques.
