一种新的异步可验证秘密分享方案

摘要

为解决在异步信道下的秘密分享方案的效率问题，采用屏蔽参数知识的思想，屏蔽参与者对验证秘密的对象和释放秘密先后的知识，提出一种在异步信道下的三轮秘密分享方案，减小因不确定轮重构造成的通信开销，保证方案的安全性。经安全性和效率两方面的分析可知，该方案在异步信道下是安全高效的。%In purpose of improving the efficiency of secret sharing in asynchronous channel , this paper proposes a 3-round asyn-chronous verifiable secret sharing scheme by hiding the knowledge about reconstruction , reduces the efficiency lost in uncertain round communication and ensures the security as well .By analysis , this scheme is of high efficiency and security .
