Implementation of security in computer designated mode system

Computer Designated Mode (CDM) plays an important role during tracking ISRO's launch vehicle, GSLV D5. It allows tracking data to be transferred from Satish Dhawan Space Centre, India to Malaysia Space Centre, Malaysia. The data are used for real time tracking. This paper looks into the development of CDM that is based on functional requirement whereas the security measure is not considered at the moment. This paper explains the architecture of CDM and how the security will be implemented on the systems. RSA algorithm is chosen as the encryption technique which will be applied in the system. Simulation result shows that this technique is feasible for the mentioned implementation.
