摘　　要：理性参与者在秘密共享过程中根据自己的效用采取行动,该概念的引入使得秘密共享方案研究面临许多新挑战。由于理性秘密共享是秘密共享研究领域一个新兴的研究方向,尚存在诸多问题有待解决。重点介绍了理性参与者效用假设,详细综述和比较了典型的理性秘密共享方案,最后指出了存在的开放问题和解决思路。目前的研究进展表明,非同步信道、复杂接入结构、安全性和可用性相结合的方案是未来重点研究方向。Rational individuals in a secret sharing scheme always choose their strategies according to expected payoffs. The research of secret sharing schemes meets many new challenges due to the concerning of rational individuals. However, as a new direction of the research field, there are many open problems waited to be solved. In this paper, the utility assumption are introduced, the classic schemes of rational secret sharing are discussed and compared in detail. In the last, the open research problems and the possible solution are pointed out. Recent related work indicates that future work will focus on the combination of security and computable in rational secret scheme in complex access structures using asynchronous communication channel.
