A protocol of the member-join in a secret sharing scheme is proposed. The proposed protocol can ensure that the original group members' keys remain invariable after the fresh member joins in the group. It makes the key management convenience. The original members can't gain the share key of the new member, and the keys of the original members don't be leaked out when distributing the share key for the new member. In the key's distributing process, the behavior of the cheaters can be detected, and the new member himself can verify the validity of his share key.
