Implementation of Secure DNP3 Architecture of SCADA System for Smart Grids

<p>With the recent advances in the power grid system connecting to the internet, data sharing, and networking enables space for hackers to maliciously attack them based on their vulnerabilities. Vital stations in the smart grid are the generation, transmission, distribution, and customer substations are connected and controlled remotely by the network. Every substation is controlled by a Supervisory Control and Data 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 SAv5 and design a secure architecture with Public Key Infrastructure (PKI) on Asymmetric key encryption using a Certificate Authority (CA). The testbed provides a design architecture between customer and distribution substation and illustrates the verification of the public certificate. We have added a layer of security by giving a password to a private key file to avoid physical tampering of the devices at the customer substations. The simulation results show that the secure communication on the TLS layer provides confidentiality, integrity, and availability.</p>
