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. -

Operation Onymous, coordinated by Europol’s Europeancopy, Cybercrime Centre (EC3), the FBI, the U.S. Immigration and Customs Enforcement (ICE), Homeland Security Investigations (HSI) and Eurojust, resulted in 17 arrests of vendors andnot administrators running these online marketplaces and more than 410 hidden services being taken down.

In this paper, we be able offer a private optical communication service as a propose Optical Onion Routing (OOR) routing and forwarding value added feature. For instance, for some client networks techniques, inspired by the onion routing in the Internet layer, - an optical network can grant anonymous access to third-party the best known realization of anonymous communication today, – but designed with specific features innate to optical networks. servers in the cloud, whereby the traffic contents and the origin We propose to design the optical anonymization network system of requests can remain secret for both the attacker as well as with a new optical anonymization node architecture, including the cloud provider. In designing an anonymous optical network the optical components and their electronic counterparts to akin to Tor, however, several obstacles need to be overcome, realize layered encryption. We propose modification to the secret since the main features need to be primarily implemented in key generation using Linear Feedback Shift Register (LFSR), – photonics, i.e., without intervention of electronics, such as able to utilize different primitive irreducible polynomials, and encryption, traffic routing, and session key distribution.
