TL;DR
This paper introduces a distributed hierarchy framework that enhances control center security in power grids by randomizing critical function locations and incorporating trust management, reducing single points of failure and improving resilience against cyber-attacks.
Contribution
A novel distributed hierarchy framework is proposed to secure critical control functions by randomizing their execution location and integrating trust management, with theoretical and practical validation.
Findings
Trust values converge over time in the proposed protocol.
System remains robust if compromised nodes are fewer than half minus one.
Framework successfully tested on hardware and IEEE 118 bus system simulations.
Abstract
Recent cyber-attacks on power grids highlight the necessity to protect the critical functionalities of a control center vital for the safe operation of a grid. Even in a distributed framework one central control center acts as a coordinator in majority of the control center architectures. Such a control center can become a prime target for cyber as well as physical attacks, and, hence, a single point failure can lead to complete loss of visibility of the power grid. If the control center which runs the critical functions in a distributed computing environment can be randomly chosen between the available control centers in a secure framework, the ability of the attacker in causing a single point failure can be reduced to a great extent. To achieve this, a novel distributed hierarchy based framework to secure critical functions is proposed in this paper. The proposed framework ensures…
