| 摘 要： | 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.

| Abstract: | 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.
