%X An efficient on-line secret sharing scheme is proposed based on the discrete logarithms and Hwang-Chang scheme in this paper,which can detect cheaters.This scheme has many strong points,each participant select his/her shadow by his/herself,so no secret communication exists between the dealer and the participants. Each participant is able to check whether another participant provides the true information or not in the recovery phase but they don't need a special check-function;each participant holds only one shadow while sharing many secrets with other participants.
