Group signatures allow any member of a potentially large group to sign on behalf of the group. Group signatures are anonymous and unlinkable for everyone with the exception of a designated group manager who can co-relate signatures and reveal the identity of the actual signer. At the same time, no one (including a group manager) can misattribute a valid group signature. Group signatures are claimed to have many practical applications in e-commerce as well as in military and legal elds. Despite some interesting and eclectic results, group signatures remain connned to academic literature. The focus of this paper is twofold. First, it discusses certain issues that stand in the way of practical applications of group signatures and uses the example of on recent group signature scheme to illustrate certain problems. Second, this paper (informally) introduces some practical security services that can be constructed using any group signature scheme. Sample realizations of these services are provided.
