The current state of full disk encryption is still not good (2025) (gpn23)


Listen Later

In theory, full disk encryption (FDE) just works. You just have to enable it. But in practice, cops get access to a lot of devices, even when they are encrypted.
I want to summarize the current state of full disk encryption. I will explain conceptional weaknesses/attacks, practical physical attacks (videos of live demos) and give recommendations. I will explain how TPMs work and how you can use them to increase (but also break) the security of your device.
The focus is on Linux and TPMs. I will briefly talk about the broken state of Smartphone Security and Window's FDE Bitlocker. There is also Linux hands-on.
##### AGENDA
- Motivation & Threat Model
- Smartphone Security
- History of cold boot attacks
- Full disk encryption on Linux
- TPM 2.0 (How does it work? How can I use it? Attacks, benefits and problems)
- Windows FDE (is currently broken)
- How I do FDE on Linux
