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。

Abstract: In purpose of improving the efficiency of secret sharing in asynchronous channel, this paper proposes a 3-round asynchronous 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.

Key words: asynchronous channel, verifiable secret sharing scheme, knowledge hidden
