Cryptography and Authentication Placement to Provide Secure Channel for SCADA

Distributed control systems (DCSs) and Supervisory Control and Data Acquisition (SCADA) systems are widely used in real time industry infrastructures such as water pumping stations, gas, and oil and other real time deployments. SCADA implementation within a cloud computing environment is new and beneficial for real time infrastructures. Using cloud computing, real time infrastructure saves cost, achieves more reliability and functionality related to the current requirements of industry in the term of control and acquisition. In current paper, the cryptyography algorithms are implements to secure data, and a conception model is proposed to implement SCADA within cloud environment and also discuss the security issues related to SCADA, and cloud computing. At the end; cryptographic solution is implemented in SCADA communication without or/and within the cloud infrastructure (Delivery of data/message from the Master terminal unit or MTU to Remote terminal unit or RTU) to achieve security services
