| Abstract: | The rational secret sharing cannot be realized in the case of being played only once,and some punishments in the one-time rational secret sharing schemes turn out to be empty threats.In this paper,after modeling 2-out-of-2 rational secret sharing based on Bayesian game and considering different classes of protocol parties,we propose a 2-out-of-2 secret sharing scheme to solve cooperative problem of a rational secret sharing scheme being played only once.Moreover,we prove that the strategy is a perfect Bayes... |
