Research on Network Intrusion Detection Strategy Based on Evolutionary Game

In response to the information security issues of wireless sensor network intrusion, this article constructed an evolutionary game benefit improvement matrix based on the actual background of attack and defense conflicts and the basic principles of evolutionary game. The stability analysis of the equilibrium strategy between the two parties is conducted, and the sensitivity of the loss parameters is discussed. Furthermore, the effect on convergence speed is analyzed, and the optimal detection strategy algorithm is proposed. Using MATLAB as the experimental platform, the accuracy and validity of the model are verified, which provides a theoretical reference for information security problems in real society.
