| 摘 要： | 基于RSA密码算法,提出一个非交互式的可公开验证的向量空间上的秘密共享方案(方案1),其中的可公开验证性是通过公开有关秘密数据的承诺而实现的,任何人在恢复秘密过程中可验证份额的有效性.并在方案1的基础上又提出了可共享多个秘密的方案2.方案1与方案2均保留了RSA密码算法与向量空间秘密共享体制的优点,安全性也是基于这两个体制的.

| Abstract: | Based on the RSA a publicly verifiable secret sharing scheme in vector space (scheme one) is proposed. The validity of the shadows can be verified. Scheme two that can share many secrets is then proposed based on the above scheme. The two schemes retain advantages of the RSA and that of the vector space in their secret sharing. Their security are also based on these two schemes. |
