He explains how Android Verified Boot (AVB) and hardware roots of trust ensure system integrity and security during startup.
Furthermore, it highlights Android's compliance requirements across various device manufacturers, ensuring consistent security standards and protection.
Kamil Aronowski introduces a game-changing approach to firmware security in light of the EU NIS2. With a focus on supply chain integrity and cybersecurity accountability, he emphasizes the importance of taking complete, self-sovereign control over cryptographic signing keys.
Aronowski demonstrates how mastering key custody with Zarhus can mitigate risks by eliminating third-party dependencies, fortifying supply chains, and providing ultimate operational resilience.

Context-Based Authentication (CBA) offers an innovative solution to securing access without relying on specialized hardware like GPS or cellular signals, which are typically used in geofencing.
This tech not only strengthens authentication but also improves the security of stationary devices, without needing extra hardware. In this talk, we will demonstrate how CBA works, showcase the technology stack behind it, and share the latest developments from the @crosscon_eu

The talk focuses on cache behavior and several possible cache attack types, explaining how they work in practice. It briefly mentions ongoing plans to test whether the @crosscon_eu hypervisor implements relevant mitigations.
The demo presents one example attack that successfully extracts data prior to any mitigation. More details are available on the event page:
