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.
(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.
