Abstract
While outsourcing databases are widely used, their security is also facing great challenges. In order to reduce the validation and communication overheads of outsourcing solutions, this paper designs a game mechanism for rational outsourcing databases based on game theory, setting incentives and defining a payoff matrix to ensure that each rational participant will only maintain an honest strategy so as not to contradict the self-interest nature and achieve a Nash equilibrium. Finally, through simulation experiments, this paper proves that the use of utility functions to secure data can reduce the user's verification overhead and communication overhead, which has important research value.
Keywords: Outsourcing database, payoff matrix, nash equilibrium
