    Abstract: "Abstract: In 1998, Lee and Chang proposed an e±cient group
    signature scheme based on the discrete logarithm. In the Lee-
    Chang scheme, when the signer has been identi¯ed, the authority
    has to redistribute the keys of this signer and send the keys to
    him/her. Otherwise, all the previous group signatures are linkable
    at the same time and any veri¯er will identify all future group
    signatures not through the authority. It is not feasible for the
    applications of the group signatures. In this paper, the authors
    shall propose an improvement of the Lee-Chang scheme to solve
    the above problems."
