| 摘 要： | 该文基于Schoenmakers的公开可验证秘密共享方案,构造了一种有成员加入的公开可验证秘密共享方案.在此方案中每个人都可公开验证子秘钥的正确性,且已有的成员无需更换子秘钥,也无需更换主密钥.与已有的公开可验证秘密共享方案相比,该方案具有较高的执行效率、安全性和实用性,并且在执行过程中无需安全信道.

| Abstract: | Based on Schoenmakers's publicly verifiable secret sharing schemes,a publicly verifiable secret sharing scheme is proposed for member expansion.In this scheme,not only the shareholder himself but also everybody can verify the correctness of his share.The old shareholders needn't change their share and the main share.Compared with other schemes,this scheme is more efficient,secure and useable,and doesn't need to have the security channel in the process of the distributing share. |
