针对秘密共享方案进行了分析和研究,指出基于二元单向函数和Shamir(t,n)门限方案的YCH多秘密共享方案无法有效防止欺诈,进而提出了一个基于RSA的防欺诈的多秘密共享方案。该方案在保留了YCH方案的优良特性同时,利用秘密片段和认证片段信息的模余关系来检测欺诈者,具有较强的实用性。
Through investigating the secret sharing schemes,points out that YCH scheme is an efficient multi-secret sharing scheme,but it does not has the property of cheat-proof.To overcome this flaw,this paper presents a cheat-proof multi-secret sharing scheme based on RSA.Security analyses indicate that the proposed scheme can resist cheat effficiently.It is capabilities for many applications.
