A Dynamic Secret Sharing Scheme Based on Key Matrix
一种基于密钥矩阵的动态秘密分享方案

In this paper we introduce a dynamic secret sharing scheme. This scheme not only can be used unrestricted times to share and resume different secret without regenerating the information in the users hands,satisfy the (k,n) threshold demand,but also can realize the asymmetric user right secret sharing and dynamically add and delete the relevant users.
