The protocol design and New approach for SCADA security enhancement during sensors broadcasting system

Several security mechanisms have been investigated and deployed that provide protection for real time platforms. Each security mechanism is contributed to enhance the SCADA system security, but at the same time, the mechanism is limited and depended on the other protocols for the purposes of message security, and its delivery. Few researches are conducted on security for SCADA broadcasting system, but these are limited to end-to-end designs and developments. The security developments for multicasting and broadcasting systems are much complicated, time consumed and/or overloaded with the cryptography mechanisms. After conducting the detail survey, a simulation environment for SCADA water pumping system is designed in-which number of nodes is configured and well known cryptography algorithms are selected, and deployed as an inclusive development for SCADA/DNP3 broadcasting system. The inclusive security development is considered with the best performance, and with predominant weakness in mind, which are present in SCADA/DNP3 broadcasting system. However, overall communication is initiated, monitored and controlled at main controller side with the user defined human machine interface (HMI).
