Blocking Misbehaving Users in Anonymizing Networks

Abstract- Internet services can be accessed privately through anonymizing networks like Tor. A set of routers are used to achieve this in order to hide the identity of client from server. The users of such networks often indulge into malicious activities and cause damage to popular web applications. The administrators of those web sites do block the IP address from which the request comes. This is not the practical solution as the hackers operate through anonymous networks. Blocking a node based on IP address will cau se misbehaving and genuine users to lost access to the web sites. This is the problem in the existing systems and motivation to take up this research work. The proposed system develops a security mechanism that ensures that only the misbehaving users are blackl isted while genuine users and their anonymity are preserved. Even though the misbehaving users are blacklisted, their privacy is still maintained. The experiments revealed that the system is able to block misbehaving users only instead of blocking the node through IP address. Index Terms: anonymizing networks, misbehaving users, blacklisting,
