Abstract :
A threshold multi-secret sharing scheme against cheating among weighted participants of special access right based on Chinese remainder theorem and LUC cryptosystem is introduced , it permits that multiple secrets be shared in one secret sharing session. The sub-secret of every participant can be used many times, and the secrets can be renewed without renewing the sub-secrets of the participants. Furthermore, the dealer can check whether each participant is honest.
