Abstract

This paper studies cryptography algorithms to be implemented into the SCADAKratos application of thermal vacuum chamber (TVC) system. SCADAKratos application is used to control and monitor the operations of the TVC which is a satellite test equipment that is located at the Malaysia Space Centre, Banting, Malaysia. The security features had been put aside during the development as it was claimed that there is no threat to the system since the system is operated internally. However, during service and troubleshooting by the manufacturer, the system will be accessed through public network. Besides that, the system also can be accessed remotely during operation for control and monitoring purpose. In addition, the testing data results also need to be transferred to the customer through the internet as it is easier and faster. The remote access through public network will cause the TVC system to face a risk to any threat and attack. Therefore, the implementation of cryptography algorithm into TVC system is needed in order to secure and protect the system from unauthorized access. This paper explains the architecture of SCADAKratos application of TVC system and how the cryptography algorithms could be implemented through this application. Secure Hash Algorithm (SHA-1) and AES algorithm (AES) are chosen as the encryption technique which will be applied in the TVC system. Simulation result shows that this technique is feasible for the mentioned implementation.
