Information leaks in structured peer-to-peer anonymous communication systems
Prateek Mittal, Nikita Borisov · 2008
We analyze information leaks in the lookup mechanisms of structured peer-to-peer anonymous communication systems and how these leaks can be used to compromise anonymity. We show that the techniques that are used to combat active attacks on the lookup mechanism dramatically increase information leaks and increase the efficacy of passive attacks. Thus there is a trade-off between robustness to active and passive attacks.
