A Longitudinal Analysis Of The Effects Of Operation Onymous In recent years, there has been a proliferation of online illicit markets where participants can purchase and sell a wide range of goods and services such as drugs, hacking services, and stolen financial information. Second- generation markets, known as cryptomarkets, provide a pseudo-anonymous platform from which to operate and have attracted the attention of researchers, regulators, and law enforcement. -
Pairing-Based Onion Routing with Improved Forward Secrecy ∗
Pairing-Based Onion Routing with Improved Forward Secrecy ∗ Aniket Kate Greg M. Zaverucha Ian Goldberg David R. Cheriton School of Computer Science University of Waterloo Waterloo, ON, Canada N2L 3G1 {akate,gzaveruc,iang}@cs.uwaterloo.ca Abstract This paper presents new protocols for onion routing anonymity networks. We define a provably secure privacy-preserving key agreement scheme in an identity-based infrastructure setting, and use it to forge new onion routing circuit constructions. These constructions, based on a user’s selection, offer immediate or eventual forward secrecy at each node in a circuit and require significantly less computation and communication than the telescoping mechanism used by Tor. Further, the use of the identity-based infrastructure also leads to a reduction in the required amount of authenticated directory information. Therefore, our constructions provide practical ways to allow onion routing anonymity networks to scale gracefully. Keywords: onion routing, Tor, pairing-based cryptography, anonymous key agreement, forward secrecy 1 Introduction Over the years, a large number of anonymity networks have been proposed and some have been implemented. Common to many of them is onion routing [RSG98], a technique whereby a message is wrapped in multiple layers of encryption, forming an onion. As the message is delivered via a number of intermediate onion routers (ORs), or nodes, each node decrypts one of the layers, and forwards the message to the next node. This idea goes back to Chaum [Cha81] and has been used to build both low- and high-latency communication networks. A common realization of an onion routing system is to arrange a collection of nodes that will relay traffic for users of the system. -

Everyone's Guide to Bypassing Internet Censorship
EVERYONE’S GUIDE TO BY-PASSING INTERNET CENSORSHIP FOR CITIZENS WORLDWIDE A CIVISEC PROJECT The Citizen Lab The University of Toronto September, 2007 cover illustration by Jane Gowan Glossary page 4 Introduction page 5 Choosing Circumvention page 8 User self-assessment Provider self-assessment Technology page 17 Web-based Circumvention Systems Tunneling Software Anonymous Communications Systems Tricks of the trade page 28 Things to remember page 29 Further reading page 29 Circumvention Technologies Circumvention technologies are any tools, software, or methods used to bypass Inter- net filtering. These can range from complex computer programs to relatively simple manual steps, such as accessing a banned website stored on a search engine’s cache, instead of trying to access it directly. Circumvention Providers Circumvention providers install software on a computer in a non-filtered location and make connections to this computer available to those who access the Internet from a censored location. Circumvention providers can range from large commercial organi- zations offering circumvention services for a fee to individuals providing circumven- tion services for free. Circumvention Users Circumvention users are individuals who use circumvention technologies to bypass Internet content filtering. 4 Internet censorship, or content filtering, has become a major global problem. Whereas once it was assumed that states could not control Internet communications, according to research by the OpenNet Initiative (http://opennet.net) more than 25 countries now engage in Internet censorship practices. Those with the most pervasive filtering policies have been found to routinely block access to human rights organi- zations, news, blogs, and web services that challenge the status quo or are deemed threatening or undesirable. -

Not long ago it was speculated that the leading world economic and political powers were engaged in a cyber arms race; that the world is witnessing a cyber resource buildup of Cold War proportions. The implied threat in that assessment is close, but it misses the mark by at least half. The threat is much greater than you can imagine. We have passed the escalation phase and have engaged directly into full confrontation in the cyberwar. -
