Will ToR Achieve Its Goals in the 'Future Internet'? An Empirical Study of Using ToR with Cloud Computing

摘要

With the wide development and deployment of mobile devices and gadgets, a larger number of users go online in so many aspects of their daily lives. The challenge is to enjoy the conveniences of online activities while limiting privacy scarifies. In response to the increasing number of online-hacking scandals, mechanisms for protecting users privacy continue to evolve. An example of such mechanisms is the Onion Router (ToR), a free software for enabling online anonymity and resisting censorship. Despite the fact that ToR is a dominant anonymizerin the current Internet, the emergence of new communication and inter-networking trends such as Cloud Computing, Software Defined Networks and Information Centric Networks places a question mark whether ToR will fulfil its promises with these trend of the "Future Internet". This paper aims at answering the question by implementing ToR on a number of Cloud platforms and discussing the security properties of ToR.
