摘要：
It has been proven to be unsafe to make the deleted member fail to pass the group signature and make the legal member implement the scheme of valid signature through updating operator scheme. Then the secret property key updating of legal member cannot be accomplished by each legal member. In this paper, a new secret property key updating operator is designed, whose work of updating the group member secret property key is done by group administrator. Its security is based on the discrete logarithm and factorization difficulty, which is resistant to collusion attacks.
