Abstract: 

In this paper, we studied the effects of sharing the bandwidth on the I2P network on the anonymity level it provides to the users. To this end, we explored what could be achieved by a potential attacker on the I2P Network in terms of application and user profiling. In both cases, the effect of bandwidth participation has been been analyzed. To achieve this, we used a machine learning based approach to analyze the flows extracted from the traffic generated by the applications and the users. Our results show that profiling the users and applications on the I2P network is possible. The amount of shared bandwidth has an effect on the accuracy of profiling the users and the applications. Furthermore, applications that do not use the shared clients tunnels increases the possibility to profile the behavior of the flows for these applications.
