Research on the Optimization Management of Cloud Privacy Strategy Based on Evolution Game

Algorithm 1

Optimal privacy strategy selection.

	Input: cloud computing attack-protect game tree.
	Output: optimal privacy protect strategy.
(1)	Initialization
(2)	Constructing protector’s space set
(3)	Constructing an optional strategy space set for protectors
(4)	According to the strategy selection of the adversary, a reasonable protect strategy is selected by probability , and
(5)	For attack –protect strategy , we get the payoff value of protect strategy.
(6)	Calculating of the protect strategy.
(7)	Calculating the average payoffs of the protector .
(8)	Establishing protector’s dynamic replication equation .
(9)	Computing equilibrium solution of .
(10)	Output privacy protect strategy.
