Abstract:

A dynamic generalized threshold multi-secret sharing scheme among weighted participants of special access right based on Chinese Remainder Theorem 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, a participant can be freely put into or removed.

Key words: special access right, threshold secret sharing, multi-secret, weighted, dynamic
