OTRv4 is the newest version of the Off-The-Record protocol. It is a protocol where the newest academic research intertwines with real-world implementations. It is also one of the first protocols that comes from the global south which makes the political discussion around protocols an urgency. This newest versions also asks us to revisit our definitions around deniability (online and offline) and how important is it to the world. In this talk we will try to start a discussion around the importance of protocols, its political/moral foundations, the real-world implementation of academic ideas, the importance of securely implementing them, the definition of deniability in the current world and the design of OTRv4.
As we know from past revelations, the Internet has become a place where any action is surveilled and recorded. In the light of this, the OTR protocol was created. But it was created long time ago. In the past years, there have been a increased work on cryptographic primitives, and privacy and security notions. But these thoughts have not been incorporated into projects. OTRv4 is the newest version of the Off-The-Record protocol, which tries to incorporate these new ideas. At the same time, OTRv4 is a protocol that challenges the common thinking around protocols as it comes from the global south, and takes moral questions into its design, as Rogaway tried to defined on his "The Moral Character of Cryptographic Work?" paper. Furthermore, OTRv4 tries to update the notion of deniability and why it is important for the world.

Six years ago the idea behind CensoredPlanet started, that is now launched at censoredplanet.org. We had a simple (yet essential) guiding principle: measurements that may be politically sensitive should be done without volunteer participation. In this talk, besides a detailed scientific overview of the techniques and the current state of CensoredPlanet, I plan to talk about my experience in developing the project from the ground up. Despite the pervasive nature of Internet censorship and the ...

We rely on mainstream computer engineering every day, but it's insanely complex, poorly understood, unreliable, and, as CCC reminds us every year, chronically insecure. This talk will explain some ways that we can do better: taming parts of this this chaos with precise understanding - illustrated with disturbing facts and clean models for current architectures and the C language, from the <a href="https://www.cl.cam.ac.uk/~pes20/rems/">REMS</a> project, and principled but pragmatic new ...

A major part of software development is maintenance, i.e. tinkering with software that should already be completed but still somehow does not work as it should. Software developed by tinkering is the antithesis to resilient technology, and a growing threat to our profession and our lives. Working on this kind of software crushes the soul. Yet this is exactly how most IoT devices (and computers in general) are programmed these days. We need to replace the dead technology-oriented objects of the ...

Learn to see the world without your eyes. Wonder what it's like to navigate while blind? Want to learn to use your everyday senses in ways you don't know you don't know? In this talk, I hack <em>you</em> with permanently enhanced sensory perceptions. This is very participatory, not just "sit and listen", and workshops are even more hands-on (blindfolded w/ cane in hand).

The internet has become essential services, and offline methods of sharing data are rapidly disappearing. Other possible networks are often better suited when connectivity is not available or affordable. Radios, sensors, and computing are available in the cheapest of smartphones and routers. Wind is integrating nearby/offline data exchange with the internet services that we all rely on.
