  • A dynamic secret sharing scheme based on discrete logarithms and factorization is proposed in this paper. It has the following advanced properties: (1) The dealer can renew system secrets without renewing the shadows of the participants; (2) When the system accepts a new participant or fires a participant, the shadows of other participants would not change; (3) When some participants shadows are revealed ,they can be renewed without any effect on the others; (4) It can detect the cheater; (5) Comunication is reduced and work efficiency is improved.
