New Member Joining in a Secret Sharing Scheme without a Trusted Party
PU Guang-ning · Journal of Chongqing University of Science and Technology · 2011
In the present secret sharing scheme without a trusted party,if there isn't a trusted party which can distribute share to every member,the new member can hardly gain his or her share.To solve this problem,a new secret sharing scheme based on the intractability of the discrete logarithm is presented.This scheme could permit a new member to join in,and the original members' share will not be leaked out when they help the new member to gain the share.The proposed scheme which is secure,fair and robust,has good practical application.
