Abstract :
This paper analyzes the probabilities of data packet loss for both an encrypted channel in self-synchronous cipher feedback mode and a nonencrypted channel, in the space data systems. Simulation results show reasonable agreement with analytical results. When channel bit error probability is 10-5 and the total number of packets per frame is 3, the analytical model gives 0.39% packet loss while the simulation gives 0.22% packet loss due to encryption. Although the analysis is performed for the space data systems, the resulting derived equations with minor change will be useful in many packet communication applications
