Misbehavior Detection Algorithm in CCSDS Space Telecommand System

Various authentication solutions are to be considered and tested for possible adoption in space Telecommand system due to the accessibility of space wireless channel. Most of the solutions proposed previously are designed oblivious of the difference in protocol misbehavior due to attacks and due to normal interference in space channel. We propose an innovative misbehavior detection algorithm for CCSDS Telecommand systems, to address this problem with a hypothesis test approach based on the model of attacker's behavior and space channel.
