Emilia Lilu Steinhauser

Hi, ich bin Emilia Steinhauser und 18 Jahre alt, womit ich bisher weder ein Studium abgeschlossen habe, noch auf irgendeine Andere Art eine Ausbildung in dem Gebiet habe. Stattdessen habe ich “nur“ letztes Jahr mein Abitur gemacht und im Zuge Dessen einen Vortrag vorbereiten müssen. Die Gelegenheit hab ich genutzt und als Thema den Versuch unternommen meine sehr unterschiedlichen Hobbys zu verbinden.
klassische Musik ist ein großer Teil meines Lebens und als Laien Bratschistin spiele ich in vielen Orchestern und Ensembles mit. Zum anderen konnte ich unteranderem durch meine Leistungskurse Mathe und Physik meine Vorliebe zu den Naturwissenschaften in und außerhalb der Schule ausleben.
In meinem Abiturvortrag: „die Physik der Musik“ habe ich sehr viel Arbeit und Freude reingesteckt und würde mich daher freuen, wenn diese Arbeit zu mehr als nur einer guten Note und meinem eigenen Vergnügen genutzt werden kann. Ich würde diese neue Sichtweise auf Musik gerne an andere Interessierte Menschen weitergeben.

Ich beschäftige mich damit, wie man (neue) Technologien einsteigerfreundlich erklären kann. Dabei ist für mich, dass hier alle selbst ausprobieren und experimentieren können. Denn ich glaube daran, dass wir so am besten lernen.

Ich bin Teil des Projektes „Quanten 1x1 – Quantentechnologien spielend leicht verstehen“ bei dem wir erste Inhalte zu Quantencomputern, -verschlüsselung, -Sensoren und was das alles mit uns und der Gesellschaft zu tun hat, entwickeln.
In dem Projekt sind bereits mehrere Spiele und Tischexperimente entstanden, so wie leicht verständliche Animationen, die wichtige Begriffe einführen und viele viele Interviews mit spannenden Expertinnen. Die Inhalte sind als OER-Materialien (Open Educational Ressources) nutzbar und ich gebe Workshops und Fortbildungen für Multiplikatorinnen.

Janine is a privacy researcher, independent investigative journalist, and educator on the topics of informational self-determination (informationelle Selbstbestimmung), financial technology, and (counter)surveillance.

  • An Introduction to Scientific Journalism

Jiska Classen is a wireless and mobile security researcher. The intersection of these topics means that she digs into iOS internals, reverse engineers wireless firmware, and analyzes proprietary protocols. Her practical work on public Bluetooth security analysis tooling uncovered remote code execution and cryptographic flaws in billions of mobile devices. She also likes to work on obscure and upcoming wireless technologies, for example, she recently uncovered vulnerabilities in Ultra-wideband distance measurement and reverse-engineered Apple's AirTag communication protocol.

She has previously spoken at Black Hat USA, DEF CON, RECon,, Chaos Communication Congress, Chaos Communication Camp, Gulasch Programmer Nacht, MRMCDs, Easterhegg, Troopers, Pass the Salt, NotPinkCon, gave various lectures and training, and published at prestigious academic venues.

Mate Soos

Mate Soos has been working both in industry as an IT security expert, and in research, working on formal methods. In industry, he has worked from low-level chip reverse engineering, staring through the microscope at a microprobed chip, through GPGPU-based cipher reversing, all the way to designing the cloud security of large firms. Within the scope of his research, he has been working on SAT and SMT solving, model counting, and uniform sampling. The two aspects of his work have sometimes coincided, e.g. when breaking the Mifare cipher using a specially-designed SAT solver, or when using SMT solvers to prove correctness of digital contracts. Lately, he's been interested in safety engineering, bringing notions from the extensive safety literature to the IT security world.
