In anonymous networks clients are allowed to access internet without compromising their privacy. Anonymizing networks provides this private sharing by using a series of routers that implements onion routing wherein the IP Address of client is hidden. Generally the websites require IP Address to uniquely identify the client and if any client tries to access the website without any valid IP Address then website administration blocks that client. Blocking IP Address is not feasible as IP Addresses are limited. Blocking anunauthorized client is needed for security but if the client is anonymous then this solution fails here. This will treat behaving and misbehaving clients alike. The aim of Misbehaving clients is to make the servers down or deface it. In existing extended Nymble system, the Nymble Manager blocks misbehaving clients temporarily for a default period of time, to avoid this there is a pseudotracker to track client's rating.In our Enhanced Nymble system the right of blocking misbehaving clients is solely given to the server and the need of a different pseudotracker and communication between PM and NM through pseudotracker is eliminated thus making the Nymble system more efficient maintaining the confidentiality of the client at the same time. © Research India Publications.
