In this paper, the authors develop a new system to enable service providers, such as website operators, on the internet to restrict past abusive users of anonymizing networks (for example, tor) from further causing trouble behavior, without compromising their security, and while maintain the security of all of the uncorrupt users. This system provides a security-preserving analogy of IP address banning, and is modeled after the well-known Nymble system. Nymble is a system that provides a restricting mechanism to a server to protect it from unauthorized users connecting through anonymizing networks such as tor.
