| Summary: | To realize the economic and reputation fairness in rational delegation of computation, a fair and rational delegation of computation scheme based on blockchain model of cryptography in the universally composable (UC) framework was proposed.Firstly, a bidirectional reputation incentive model between the delegator and the calculator was presented by combining direct reputation and indirect reputation.Secondly, a dynamic game model with perfect information for fair and rational delegation of computation was constructed based on game theory, and a unique sub-game Nash equilibrium was further obtained.In addition, by analyzing the requirements for verifiability, rational decision of players, economic and reputation fairness, as well as adversary model, the ideal functionality for fair and rational delegation of computation was proposed.Finally, a fair and rational delegation of computation protocol by combining succinct commit-and-prove and smart contract was proposed to securely realize the ideal functionality.The security analysis shows that the proposed protocol satisfies UC security. |
