Fault Injection on a modern multicore System on Chip

Hardware attacks on security relevant components, such as fault injection, have been known for decades and have been shown to be successful on a wide range of devices ranging from general purpose microcontrollers to dedicated security engines. In this work we give an overview of different methods used for fault injection and the effectiveness of these methods. We discuss electromagnetic fault injection in more detail. Most of the published research focuses on attacking low performance secure devices. However, we present the results of electromagnetic fault injection on a modern multicore system on chip running at gigahertz speed and discuss its effectiveness.
In this presentation we discuss hardware attacks in general, their use cases, and real-world examples. We then discuss electromagnetic fault injection in detail. We compare the results of the previous research on microcontrollers and secure elements to more modern high performance system on chip devices. We discuss relevant features of modern Arm systems on chip and answer the two main questions of this research. Are electromagnetic fault injection attacks applicable and efficient when applied to software running at gigahertz speed on a modern multicore system on a chip? And to what extent does the operating frequency change the effectiveness of electromagnetic fault injection attacks?

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 ...
