摘要
分析了传统的秘密共享算法的不足之处,提出了相应的优化方案,形成了先验式秘密共享方案,包括初始化、份额更新、份额恢复和秘密重构,实现了先验式秘密共享协议的各种算法,充分考虑了秘密分享的各个阶段可能遇到的问题,并分别给出了相应的解决方案。
The article first analyses the shortcomings of traditional secret-share algorithm, presents a corresponding optimization scheme, forms prior share-secret scheme, including initialization of share、renewal of share、recovery of share and reconstruction of secret with verification. The paper realizes all algorithms of prior secret-share protocol, and considers possible problems in each phase of secret-share and presents corresponding settlement scheme.
