Improvement of nuclear facilities DNP3 protocol data transmission security using super encryption BRC4 in SCADA systems

Background Data transmissions using the DNP3 protocol over the internet in SCADA systems are vulnerable to interruption, interception, fabrication, and modification through man-in-the-middle (MITM) attacks. This research aims to improve the security of DNP3 data transmissions and protect them from M...
