Enhanced Nymble for Blocking Misbehaving Users over Anonymizing Networks

Anonymity networks such as TOR provide users with a means to communicate privately over the Internet. These networks help to solve the real and important problem of enabling users to communicate privately over the Internet. But some users misuse this service and they tried to deface popular websites like wikipedia. To counter such users, a system called Nymble is used. But there is a possibility of collusion of components of Nymble such as Pseudonym manager and Nymble manager. This results in security problems. Also Nymble is not scalable and robust. In this paper, we propose a method which avoids the chance of collusion between Pseudonym manager and Nymble manager and also this method is scalable and robust.
