Information leaks in structured peer-to-peer anonymous communication systems
2008
Proceedings of the 15th ACM conference on Computer and communications security - CCS '08
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. We study this trade-off in two P2P anonymous systems, Salsa and AP3. In both
