A dynamic(t,n) threshold signature authentication scheme without a trusted party
Hu Donghui · Journal of Hefei University of Technology · 2011
A dynamic digital signature authentication scheme without a trusted party is proposed based on(t,n) threshold secret sharing.All of the group members together generate the group's private key and at least t members can generate the signature certificate.The members are allowed to join or leave without changing the group's private key,which are managed dynamically.The scheme is proved to be safe,correct and easier to implement.
