Abstract
At present, most network security analysis theory assumes that the players are completely rational. However, this is not consistent with the actual situation. In this paper, based on the effectiveness constraints on both sides with network attack and defense, with the help of stochastic Petri net and evolutionary game theory, the Petri net model of network attack and defense stochastic evolutionary game is reconstructed, the specific definition of the model is given, and the modeling method is given through the network connection relationship and attack and defense strategy set. Using this model, a quantitative analysis of network attack events is carried out to solve a series of indicators related to system security, namely, attack success rate, average attack time, and average system repair time. Finally, the proposed model and analysis method are applied to a classic network attack and defense process for experimental analysis, and the results verify the rationality and accuracy of the model and analysis method.
Highlights
In recent years, with the rapid development of information technology, it has provided great convenience for the country’s scientific and technological development and the people’s living needs
The basic characteristics of game theory are target opposition, strategic dependence, and noncooperation. erefore, game theory has become a popular method for theoretical analysis and modeling of network security proposed in recent years [6, 7]
Liu et al [13] proposed a network attack and defense game model based on Bayes Nash equilibrium, solved the attack and defense problem through the utility maximization problem, and focused on the attack and defense game problem of insecure information network based on risk aversion
Summary
With the rapid development of information technology, it has provided great convenience for the country’s scientific and technological development and the people’s living needs. Erefore, in order to improve the rationality and accuracy of the model, this paper will take the attack and defense sides of the network under the condition of bounded rationality as the problem object, with the help of evolutionary game theory and stochastic Petri net, construct a network attack and defense model based on stochastic evolutionary game Petri net, and analyze the security of the attacked network system. (2) We propose to apply stochastic Petri net and evolutionary game theory in the evaluation process of network trust model and discuss the detailed simulation scenarios of modeling. A Petri net model of stochastic evolutionary game of network attack and defense can be represented by a 9-tuple: AD − SEGPN {N, P, T, F, π, λ, Δ, U, M}. (7) Δ δNa, δNb is the set of random interference intensity coefficients; δNa is the influence strength coefficient of random interference on the attacker; δNd is the influence intensity coefficient of random interference on the defender
