How can we take a stand against the increasing shadow of Internet censorship? With OONI Probe you can join us in uncovering evidence of network interference! During this talk we will give you an overview of the challenges people around the world face when accessing the internet. In 2017, we have witnessed multiple cases of Internet censorship being used as a tool to suppress controversial politica...

The NERF and Heads projects bring Linux back to the cloud servers' boot ROMs by replacing nearly all of the vendor firmware with a reproducible built Linux runtime that acts as a fast, flexible, and measured boot loader. It has been years since any modern servers have supported Free Firmware options like LinuxBIOS or coreboot, and as a result server and cloud security has been dependent on unrevie...

During 2016 Libre Space Foundation a non-profit organization developing open source technologies for space, designed, built and delivered UPSat, the first open source software and hardware satellite. UPSat is the first open source software and hardware satellite. The presentation will be covering the short history of Libre Space Foundation, our previous experience on upstream and midstream space p...

What does policing look like in the age of data exploitation? This is the question we at Privacy International have been exploring for the past two years. Our research has focused on the UK where the population has been used as guinea pigs for ever more invasive modern approaches to policing. In this talk we will discuss our findings with you and avenues for change. Society is changing – the citie...

An overview and history of various tools and languages that allow you to use code rather than CAD software to design circuits. For anyone used to expressing their ideas with code using a CAD tool to design electronics can be an even more frustrating exercise than normal. If you are a programmer thinking about getting into designing circuits or if you have ever thought "I could easily solve this wi...

Bitcoin arrived eight years ago, and has now spawned a dazzling array of follow-on technologies, including smart contracts, censorship-resistant computation, trustless databases (“blockchains”) and more. This talk attempts to highlight a few of the most significant developments in both technology and in society's response to it, including some nation-state governments banning cryptocurrencies and/...

Taxation, the most "boring" #34c3 talk, but hey it's the economy stupid, and you pay for it! We will a provide a quick overview of the international taxation system. Explaining what a Double Irish Sandwich is. Why international corporations like Google only pays 2.4% taxes. And how your favourite tech companies (Google, Amazon, Apple, Microsoft, ... ) evaded billions in taxes. This tax-dodging cos...

Digital Restrictions Management (DRM) is found everywhere from music to cars and, most recently, World Wide Web Consortium recommendations. How did we get here and where are we going with DRM? Who really owns not just your tools, but your experiences when someone (or something) else is controlling access to the data and access around them? We'll attempt to answer these questions, and more, in a hi...

Die Sicherheitsdesaster bei der Schlüsselgenerierung in TPM Chips und bei der Minix 3 basierten Intel ME Implementierung zeigen, dass das Vertrauen in hardwaregestützte Coputersicherheit grundlegend hinterfragt werden muss. Die Robustness in feindlicher Umgebung kann mit anspruchsvolleren kryptographische Verfahren mathematisch abgesichert erhöht werden. Kryptographie hilft gegen sehr mächtige Ang...

Our lives are on our laptops – family photos, medical documents, banking information, details about what websites we visit, and so much more. Digital searches at national borders can reach our personal correspondence, health information, and financial records, allowing an affront to privacy and dignity which is inconsistent with the values of a free society. While privacy and security is important...

In this presentation I start off asking the question „How come there are only a handful of BSD security kernel bugs advisories released every year?“ and then proceed to try and look at some data from several sources. It should come as no surprise that those sources are fairly limited and somewhat outdated. The presentation then moves on to try and collect some data ourselves. This is done by activ...

The representation of thunderstorms (deep convection) and rain showers in climate models represents a major challenge, as this process is usually approximated with semi-empirical parameterizations due to the lack of appropriate computational resolution. Climate simulations using kilometer-scale horizontal resolution allow explicitly resolving deep convection and thus allow for an improved represen...

This talk covers the theory, the required tools and how to make them, and the process of turning apples into juice, ferment them, and enrich the alcohol content of the product. We will present our high-pressure, drm-free juice press which we used to turn our hand picked apples into juice. Then we present a simple setup to ferment the juice (or other stuff, maybe even mate ;) ) to turn it into an a...

Airborne wind energy is the attempt to bring the digital revolution to the production of energy. It means that we convert the power of high-altitude winds into electricity by autonomously controlled aircraft which are connected to the ground via a tether. This technology can be a key element to finally power the world by clean energy only. In this talk we will explain the physical foundations, giv...

International commitment to the appropriately ambitious Paris climate agreement and the United Nations Sustainable Development Goals in 2015 has pulled into the limelight the urgent need for major scientific progress in understanding and modelling the Anthropocene, the tightly intertwined social-techno-ecological planetary system that humanity now inhabits. The Anthropocene qualitatively differs f...

An overview of the SatNOGS project, a network of satellite ground station around the world, optimized for modularity, built from readily available and affordable tools and resources. We love satellites! And there are thousands of them up there. SatNOGS provides a scalable and modular platform to communicate with them. Low Earth Orbit (LEO) satellites are our priority, and for a good reason. Hundre...

Once full automation hits, we will have a lot of free time on our hands. This project demonstrates early explorations in computer generated music via robot hands, old computers and generative algorithms. While the robot performs, we sit next to it and invite people for a conversation about robots being “creative” and “stealing our jobs”. “Robot Music” is an ongoing robotic research project between...

Climate change has long ceased to be news to many people, but it is increasingly shaping humanity's reality. This talk sheds light on the changes in the climate system and their consequences. We introduce the basics and discuss possible actions in response. I. Understanding the Climate System We begin with the physical basics, guided by visualizations rather than focussing on the math. What do we...

Avatar² is an open source framework for dynamic instrumentation and analysis of binary firmware, which was released in June 2017. This talk does not only introduce avatar², but also focuses on the motivation and challenges for such a tool. Dynamic binary instrumentation and analysis are valuable assets for security analysis and testing, and while a variety of tools exist for desktop software, the...

After four years of advocacy and lobbying to enshrine net neutrality principles in law in Europe, we can now examine the first full year of enforcement of the new rules. We will compare the enforcment of net neutrality in the individual EU member states, showcase a few of the more creative net neutrality violations and demonstrate what civil society can do to keep the Internet neutral. Enforcing n...

Holography of Wi-Fi radiation Philipp Holl [1,2] and Friedemann Reinhard [2] [1] Max Planck Institute for Physics [2] Walter Schottky Institut and Physik-Department, Technical University of Munich When we think of wireless signals such as Wi-Fi or Bluetooth, we usually think of bits and bytes, packets of data and runtimes. Interestingly, there is a second way to look at them. From a physicist's pe...

Since SDR (Software Defined Radio) becomes more popular and more available for everyone, there is a lot of projects based on this technology. Looking from the mobile telecommunications side, at the moment it's possible to run your own GSM or UMTS network using a transmit capable SDR device and free software like OsmoBTS or OpenBTS. There is also the srsLTE project, which provides open source imple...

How can we feed a growing world population within a resilient Earth System? This session will present results from our cybernetic computer models that simulate how future trends in population growth, diets, technology and policy may change the global land cover, freshwater usage, the nitrogen cycle and the climate system, and how more sustainable pathways can be reached. We want to discuss how our...

How do we keep important environmental and climate data accessible amidst political instability and risk? What even counts as an “accessible” dataset? Could we imagine better infrastructures for vital data? By describing the rapid data preservation efforts of U.S. environmental data that started in the wake of the recent election, I’ll address these questions and the new and existing issues that p...

There exists no such thing as a perfect anonymity network with low latency, low bandwith consumption which provides strong anonymity. Popular anonymisation networks rightfully focus on Web browsing, because that is the most popular application on todays Internet. The most popular anonymisation network is, rightfully so, Tor. You might, however, not have the requirements that mandate the use of the...
