Implementation of Secure DNP3 Architecture of SCADA System for Smart Grids
… Acquisition (SCADA) system which communicates on DNP3 protocol on Internet/IP which has many security vulnerabilities. This research will focus on Distributed Network Protocol (DNP3) communication which is used in the smart grid to communicate between the controller devices. We present the DNP3 …

Experimental analysis and modelling of an information embedded power system
… characteristic of Distributed Network Protocol (DNP3) over wide area network (WAN). In this experiment, real time data were sent from Intelligent Electronic Devices to utility control center using WAN. Experimental work reveal that measurement delays associated with DNP3 over WAN is high, as this …

Detection and prevention of intrusions in power system cyber-physical infrastructure
… use to execute attack strategies, we integrate a DNP3 analyzer in Bro and develop a semantic analysis framework. The DNP3 analyzer is the first network IDS that fully supports communication protocols used by SCADA systems in power grids. The analyzer leverages a newly proposed adaptive power flow …

Analysis of Privacy-aware Data Sharing in Cyber-physical Energy Systems
… (ICS) protocol, distributed network protocol 3 (DNP3) with the blockchain network to ensure smooth operation. In addition, we develop differential privacy (DP)-enabled strategies to achieve data security, privacy, and utility requirements of the power system network under an adversarial setting. …

Power grid simulation, evaluation, and test framework
The Virtual Power System Testbed (VPST) at the University of Illinois at Urbana-Champaign is part of the Trustworthy Cyber Infrastructure for the Power Grid (TCIP) and is maintained by members of the Information Trust Institute (ITI). VPST is designed to be integrated with other testbeds across the …
