Abstract
For the communication security problem of telemetry,tracking and command(TT&C) data on unmanned platform,a reverse analysis model of TT&C protocol is proposed.The model adopts the data mining method to analyze the protocol format and semantic information in the message.The improved Brute-Force(BF) algorithm is used to perform the pattern string matching,and the AP(Affinity-Propagation) algorithm is used to perform the association rule extracting.Then the preliminary format of protocol message is obtained.The improved Smith-Waterman(SW) algorithm in sequence alignment technique is adopted to analyze the format and semantic information in combination with the monitoring state data.Simulation experiments are carried out to simulate the experimental data of the protocol reverse analysis,including the communication data on unmanned platform and base station and radar monitoring status data.The simulation results of reverse analysis show 100% resolution rate of protocol format and 90.9% semantic parsing resolution rate.The results demonstrate the effectiveness of the model.关键词
