Enhancing Security by Broadening Nymble System in Anonymizing Networks

This paper presents Nymble, a system in which servers can blacklist misbehaving users, thereby blocking users without compromising their anonymity. The authors' system is thus agnostic to different servers' definitions of misbehavior servers can blacklist users for whatever reason, and the privacy of blacklisted users is maintained. In pseudonymous credential systems users log into Web sites using pseudonyms, which can be added to a blacklist if a user misbehaves. Anonymous credential systems employ group signatures. Basic group signatures allow servers to revoke a misbehaving user's anonymity by complaining to a group manager. Anonymous networks allow anyone to visit the public areas of the network.
