Secure and Reliable Communications for SCADA Systems
Uninterrupted electric power distribution is vital for modern society. Secure data transfer between control center and power stations is critical for controlling and protecting power distribution. Supervisory Control And Data Acquisition (SCADA) systems are used for controlling the power stations. SCADA systems have traditionally used a limited propriety communication networks to transfer only control signals between centralized control systems and power stations. To improve security and reliability of an electrical power distribution, a video surveillance is required at power stations and distribution centers. Current telecommunication networks used for the SCADA system does not provide required capacity for real time video streaming.
