DeepSec Video: HORNET – High-speed Onion Routing at the Network Layer

René Pfeiffer/ February 22, 2016/ Conference, Internet, Security

Given that reconnaissance is the first step of a successful attack, anonymity has become more important than ever. The Invisible Internet Project (I2P) and the TOR project are prominent tools to protect against prying eyes (five or more). TOR is widely used. Users of anonymity services will notice that the price for extra protection is less speed in terms of latency and probably bandwidth. Researchers have published a method to attain high-speed network performance, called HORNET. HORNET is designed as a low-latency onion routing system that operates at the network layer thus enabling a wide range of applications. Our system uses only symmetric cryptography for data forwarding yet requires no per-flow state on intermediate nodes. This design enables HORNET nodes to process anonymous traffic at over 93 Gb/s.

DeepSec Video: Measuring the TOR Network

René Pfeiffer/ February 13, 2016/ Conference, Internet, Security

A lot of people use TOR for protecting themselves and others. Fortunately the TOR network is almost all around us. But what does it do? How can you get access to metrics? TOR is an anonymisation network and by design doesn’t know anything about its users. However, the question about the structure of the user base often arises. Some people are just interested in the size of the network while others want details about the diversity of its users and relays. Furthermore, TOR is used as a circumvention tool. It is interesting to automatically detect censorship events and to see how the number of users changes in those countries. TOR’s measurement team tries to give answer to those (and more) questions. At DeepSec 2015 Jens Kubieziel explained the collection of different data and how
