Ferris wheel: A ring based onion circuit for hidden services

摘要

The capability that a server can hide its location while offering various kinds of services to its clients is called hidden services or location-hiding. Almost previous low-latency anonymous communication systems such as Tor, MorphMix, etc., that can be used to implement hidden services are vulnerable against end-to-end traffic analysis attack. This paper introduces Ferris wheel, a novel architecture for implementing hidden services which is robust against end-to-end traffic analysis attack. Moreover, our scheme is more robust against various traffic analysis attacks than previous low-latency anonymous communication architectures.
