%X A new membership revocation method based on the ACJT group scheme was provided.In this new scheme,the size of public key only lay on the number of members in the group,and would not increase infinitely along with the increase of number of members which were revoked.It needed only a multiplication or division to update the public key for the group manager to add or exclude a group member.The signing and verifying procedure were simpler than previous ones.The security of the new scheme was proved.
