Security Assumptions for Ubiquitous Secure Smart Grid Infrastructure using 2 Way Peg Blockchain and Fuzzy Specifications

Abstract

The smart grid cyber-physical system and advanced metering infrastructure is an immensely growing term in industrial research based on the electrical power grid system and has uncovered an efficient paradigm for the power generation, transmission, and for the expenditure management as well. These systems allow home area networks and advanced metering infrastructure to communicate bi-directionally. False data injection is a new and climacteric security threat to the power grid to tamper such important data. However, these communication channels that the energy service interfaces provide two-way communication according to the central control unit. Thus, for the security and robustness of the grid, it is critical to separate the false or infected data. The existing protocol on this problem is based on state estimation which is less secure and computationally expensive. In this paper, we propose a 2-way peg blockchain security system by providing a digital signature scheme between home area network device (Smart Meter) and AMI server to get authorization, providing an infected data detection algorithm based on fuzzy rule specification and 2WP based blockchain protocol and finally infected performance reputation updating algorithm by computing the probability distribution of uncouth level to detect the infected or compromised the. We get more efficiency and security by performing a detailed analysis.
