Study on Stochastic Differential Game Model in Network Attack and Defense

Algorithm 1

Optimal defense strategy selection algorithm.

	Input, who participated in the game and host node information.
	Output Attack strategy , optimal defense strategy .
	Begin
(1)	Initialize /∗ Initialize stochastic evolutionary game model∗/
(2)	Construct x, y/∗ Construct the group probability of the selected strategy set of both attack and defense ∗/
(3)	Constructing a stochastic evolution game matrix between attack and defense
(4)	Construct the stochastic differential equation of the attackers and defenders, and see equation (10) for details.
(5)	Numerical analysis of the equation using the explicit Euler equation
(6)	Back ,
