Abstract: As we studied in our literature, the recent method was presented for blocking of misbehaving user in the Tor networks called as Nymble. However the limitation which we identified for Nymble is that if the Nymble manager fails, then whole security system is fails. And hence this approach is heavily vulnerable for failure risks. Thus in this paper we are presenting the new extended method for overcoming above said problems. In this paper we propose a secure Misben system, where users acquire an ordered collection of Misbens, a special type of pseudonym, to connect to Websites. Without additional information, these Misbens are computationally hard to link and hence, using the stream of Misbens simulates anonymous access to services. Web sites, however, can blacklist users by obtaining a seed for a particular Misben, allowing them to link future Misbens from the same user. Servers can therefore blacklist anonymous users without knowledge of their IP addresses while allowing behaving users to connect anonymously. Our system ensures that users are aware of their blacklist status before they present a Misben, and disconnect immediately if they a0072e blacklisted. For the risk free and reliability of proposed approach we also proposed architecture with details that if first misben manager failed to generate seed when it get complaint from server, in previous systems in that condition system get collide and then anonymizing network in trouble ,so provide solution to this problem we introduced new 2nd misben manager.
