A method of behavior analysis and detection based on process algebra is proposed.The system flow chart is obtained through static analysis of binary code and converted into process expression. By eliminating the expression uncertainty, adding concurrent operations and reducing and merging And so on.According to the concurrency rules, the concurrency operator in the process expression is eliminated, the behavior detection model of distributed system is established, and the method of behavior detection is given.The theoretical analysis and experiments show that the proposed method reduces The complexity of behavioral analysis and detection has good accuracy in control flow analysis.
