Abstract: This article presents a dynamic multi-secret sharing scheme in any access structure based on Shamir's secret sharing.This scheme splits and reconstructs the secrets using the method of the Lagrange interpolation.This scheme can dynamically join or delete the participants and dynamically renew multi-secret,without re-distributing the sub-secrets.The sub-secrets are kept secretly by the participants.It is the shadows of the sub-secrets that are submitted by the participants during the reconstruction of the multi-secret.And any party can verify the correctness of the shadows from the public information,thus the sub-secrets can be re-utilized.
