Secure Cryptography Testbed Implementation for SCADA Protocols Security

Modbus protocol and IEC 60870-5-104 protocols are widely deployed in critical infrastructure sectors or SCADA systems. With the growing demands of industries, these protocols are also connected over internet using TCP/IP protocol or other transport protocols. Using internet facility, these protocols are vulnerable from several threads/attacks. The current research, detail review the lack of security issues within SCADA/Protocols communication and then propose two security solutions that are based on cryptography algorithms (solutions). The two proposed cryptography solutions have been implemented within the communication of Modbus protocol and IEC 60870-5-104 protocol as part of SCADA system. Abnormal traffic has been generated during transmission to evaluate the security solutions (Implementations). Testbed has been run several times and performance results are measured during normal and abnormal communication.
