Reverse analysis of measurement and control protocol based on the monitoring state data for unmanned platform

In allusion to the communication security problem of measurement and control data on unmanned platform, a reverse analysis model of measurement and control protocol is proposed. The model adopts the data mining method to analyze the protocol format and semantic information in the message. Mainly adopts the improved BF algorithm and the AP algorithm to carry on the pattern string matching and the association rule extracting to obtain the preliminary format of protocol message; the improved 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 a higher resolution rate of protocol format and semantic parsing.
