Dynamic(t,n) Threshold Secret Sharing Scheme Based on Circle Properties
基于圆性质的动态（t，n）门限秘密共享方案

A dynamic threshold secret sharing scheme based on circle properties was proposed.A two-variable one-way hash function and a notice board were introduced.A participant computes his shadow information by using both the public information and his pseudo-shadow.The pseudo-shadow of each participant always keeps the same even if a participant leaves/joins,or the value of t changes dynamically.Further more,the participants can share next secret by the same pseudo-shadow.Compared with a geometric approach for sha...
