ABSTRACT: Deleting group members safely and
efficiently has been a hot research issue in the field of the group signature.
Some resolutions have been proposed by cryptography experts, but in some way,
problems like loophole and low efficiency have been confusing us in the
research. To solve the problem, the writers try to give a new secret key
updating algorithm based on improving Wang Shangping’s group members deleting
scheme, and analyze the safety and efficiency of implemen- tation
systematically in the paper.
