Modernizing the Tor Ecosystem for the Future

Abacus 🧮
Alexander Færøy
In this presentation, we will be updating the audience on the ongoing modernization efforts of the software developed inside The Tor Project -- the organization behind the most widely deployed anonymity network. We will look at upcoming features and changes to the core technology that drives the Tor network and why a Browser may no longer be the only product we have to provide for the user-base that is so crucial in need of Tor's anonymity properties for safe internet access.
The Tor ecosystem is currently going through a more extensive modernization phase where we are simplifying our goals slightly to make space for larger projects that we find necessary. This work includes implementing a new, more memory-safe Tor implementation in the Rust programming language named Arti. This work will make it easier for application developers to integrate their applications and benefit from the safety features that Tor can provide. Additionally, we will talk about some recent or upcoming changes to the network: - Give a status update on deploying modern congestion control algorithms in the Tor network. This work should significantly enhance the performance barrier that most Tor users experience. - The roadmap towards UDP support in the client and relay software. This work should allow more modern use-cases of the Tor software such as voice and video communication, WebRTC, and other protocols that leverage datagram-based data transfer. - Move to more modern cryptography in Tor's protocols, including support for Post-quantum cryptography and why this is needed. - Allowing Tor users to access the network using a VPN-like tunneling mechanism as an alternative to simply web-browsing and other socks5 enabled applications.

What do big tech, synthesizers, the crucifixion and Matthäus Passion have in common? Find the answer in the tech performance The Silicon Passion. We’ve all embraced big tech —but is it a warm hug or a strangulation? Bear witness to a debate of biblical proportions between tech nerds, technology and its users. In The Silicon Passion SETUP, in collaboration with de Transmissie (David Schwarz en Derk Stenvers) and Rodrigo Ferreira, is looking for a way out of the pit that technology has ...

Lightning talks are a 5 to 10 minute quick talk on an interesting subject. They can be with or without slides, and with or without proper preparation. if you weren't accepted in the main CfP, this is also a great opportunity to give an abridged version of your talk. These sessions will be available to sign up to later on, with details on the wiki.

This is a submission for a keynote talk at MCH2022. The Internet is both a familiar, comfortable place as well as a bottomless rabbit hole you can lose yourself in. The Internet has always been like this from its inception, the difference now is the scale and consequences are almost immeasurable - and it tests the limits of human imagination. When you look into the mirror of the Internet what you see reflected back depends on what you are looking for. It has become largely a reflection of ...

Thanks to DNSSEC and DANE, it is possible to automatically verify user@domain.name identities by checking with domain.name servers. The real problem however, is integration with existing protocols, instead of inventing something completely new and perhaps web-only. The purpose of our work on Realm Crossover mechanisms has been to design generic solutions that extend many different application protocols, without changing their protocol specs.

Utilizing collaborative security to collect data on attacks we were able to detect Log4J in a quite unusual but effective manner. We'll show you how CrowdSec enables the entire infosec community to stand together by detecting attempts to exploit a critical 0day, reporting them centrally thereby enabling anyone to protect themselves shortly after the vulnerability was made public. The unusual part is that this is done using FOSS software and by analyzing logs of real production systems but in a ...

Building on the very well attended DNA presentations ("DNA: The Code Of Life") at SHA2017, this talk will cover: * A brief recap what DNA is and how it works * It is surprisingly digital! * How reading DNA is within 'pro-sumer' reach now * (I might bring a live demo for after the talk) * An overview of DNA editing technologies (offline, and online: on living organisms) * Including the famous CRISPR-CAS, but also newer variants * How does such editing actually work in a lab? * The surprising lack ...
