Cooperate Delegation of Computation for Rational Party Using Zero-Determinant Strategy Approach

Delegating calculation is an important approach to solve the correctness and reliability of task subcontracting and delegating calculation results in cloud computing environment. However, the dynamic, complexity and openness of cloud computing bring unprecedented risks to the security and reliability of computing tasks. To solve the problem the new approach is presented. Firstly, the game theory is introduced into the delegating calculation, and the single-client and multi-server rational delegating calculation game model is given. Secondly, the Zero-determinant Strategy scheme based on delegating calculation is constructed through implementing the single-client and single-server rational delegating calculation protocol and Zero-determinant Strategy, and the conditions of the existence of Nash equilibrium of Zero-determinant Strategy is analyzed. Then, through the iterative implementation of the Zero-determinant Strategy, the participants will cooperate with each other actively. Finally, the performance analysis results show that the entrusting party can regulate the betrayers in the computing party through Zero-determinant Strategy to ensure the interests of honest people in cloud computing.
