双通道

And then, this dissertation proposed a secret sharing scheme of secure vector space based on quadratic residue.

利用特定条件下计算二次剩余的困难性，恢复秘密时验证各参与者提供的份额的有效性，也=肖清华二杜绝了恶意参与者欺诈的可能性；(2)在秘密共享一多重签名方面，本论文针对数字签名的可跟踪性，以及确认签名是否来自同一个参与者授权子集这两个问题，指出了秘密共享和多重签名各自存在的不足，在此基础上，把两者结合起来，并从门限秘密共享一多重签名、矢量空间秘密共享一多重签名两方面对秘密共享一多重签名技术进行探讨，把 Sunder一Kumar门限秘密共享一多重签名方案推广到更为广泛的矢量空间上，并独立地提出了一个双通道的安全矢量空间秘密共享一多重签名方案。
