Dynamic vector space secret sharing based on certificates
Xu Chunxing, Jiajia Li, Dongsu Liu · Wuhan University Journal of Natural Sciences · 2006
A vector space secret sharing scheme based on certificates is proposed in this paper. The difficulties of solving discrete logarithm assure confidential information's security, and the use of each participant's certificate makes the dealer have no need to transfer secret information to the participants. The proposed scheme is dynamic. It can effectively check cheaters and does not have secure channel requirements.
