Blockchain-Based Decentralized Replay Attack Detection for Large-Scale Power Systems
نویسندگان
چکیده
Large-scale power systems are composed of regional utilities with assets that stream sensor readings in real time. In order to detect cyberattacks, the globally acquired, real-time data needs be analyzed a centralized fashion. However, owing operational constraints, such sharing mechanism turns out major obstacle. this article, we propose blockchain-based decentralized framework for detecting coordinated replay attacks full privacy data. We develop Bayesian inference employing locally reported attack probabilities is tailor made blockchain framework. compare our traditional algorithm based on broadcast gossip both theoretically as well empirically. With help experiments private Ethereum blockchain, show approach achieves good detection quality and significantly outperforms gossip-driven approaches terms accuracy, timeliness, scalability.

A partition-based algorithm for clustering large-scale software systems
Clustering techniques are used to extract the structure of software for understanding, maintaining, and refactoring. In the literature, most of the proposed approaches for software clustering are divided into hierarchical algorithms and search-based techniques. In the former, clustering is a process of merging (splitting) similar (non-similar) clusters. These techniques suffered from the drawba...
متن کاملAN OBSERVER-BASED INTELLIGENT DECENTRALIZED VARIABLE STRUCTURE CONTROLLER FOR NONLINEAR NON-CANONICAL NON-AFFINE LARGE SCALE SYSTEMS
In this paper, an observer based fuzzy adaptive controller (FAC) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. It isassumed that functions of the subsystems and the interactions among subsystems areunknown. By constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...
متن کاملNonlinear decentralized control of large-scale power systems
This paper describes an application of nonlinear decentralized robust control (Guo, Jiang & Hill, 1998) to large-scale power systems. Decentralized power controllers are designed explicitly to maintain transient stable closed-loop systems. For the "rst time, nonlinear bounds of generator interconnections are used which achieves less-conservative control gains. The proposed controllers are robus...
