So-called Secure Encrypted Virtualization (SEV) was developed by AMD with the primary goal of making its cloud services more secure. But even the latest versions of the security feature, SEV-ES (Encrypted State) and SEV-SNP (Secure Nested Paging), were vulnerable to a software-based attack until recently. This was discovered by CISPA researcher Ruiyi Zhang, who works in the team of CISPA- Faculty Dr. Michael Schwarz. He constructed a type of attack called CacheWarp, which in the worst case enables attackers to gain comprehensive access rights to data and even the possibility to manipulate it - something that was not possible with previous attack techniques. Zhang was supported by his research team at CISPA and Andreas Kogler from Graz University of Technology. According to AMD, the vulnerability has now been fixed with an update.
Cybersecurity is a young and fast-evolving field. As a Helmholtz Center for Information Security, CISPA is dedicated to cutting-edge foundational research combined with innovative application-oriented research in the areas of cybersecurity, privacy, and artificial intelligence.
CISPA PODCAST TL;DR
That text was way too long, so you didn't bother reading it? We feel you! In TL;DR, CISPA's first podcast, we talk to researchers about their work on cybersecurity and artificial intelligence. Once a month, we try to ask them the exact same questions that our listeners are asking themselves.
People from 43 nations work at CISPA. That's why you'll find conversations in both German and English in this feed.
Have fun listening!
CISPA Zine: composed of CISPA and magazine, derived from the idea of the "fanzine." Fanzines are mostly small, folded magazines on various topics, created by fans for fans. The CISPA Zine is published quarterly and keeps our colleagues, supporters, and interested parties up to date on all important developments at the center.
The targeted support of emerging researchers is part and parcel of our self-understanding as a world-leading research center. We support PhD students in almost all of our research areas, including cybersecurity, data protection, cryptography, machine learning, data science, efficient algorithms, network security and program analysis.
PhD students who are enrolled at one of at one of the universities we cooperate with are eligible for the position of research assistant at CISPA. We are always looking for outstanding academic talent from all over the world. Candidates must hold a degree from a first-rate, research-oriented university in a subject relevant to our research interests. They should also possess an exceptional academic record, a good command of the English language as well as convincing letters of recommendation from their mentors or supervisors. At CISPA, our working language is English.
It is our goal to train and hire top researchers and to accompany them in all stages of their scientific career. We want to help them advance as learners, from bachelor's or master's degrees to doctorates and postdoc or faculty-level positions.
No matter what career step you want to take at CISPA, we offer everyone a stimulating, international, competitive, yet collaborative and, above all, enjoyable working environment for research and education. We firmly believe that this is how we can all reach our full potential.
