Unlocking FileVault

An analysis of Apple's encrypted disk storage system

Analysis of the MacOS X storage encryption technology FileVault. Having fun by reverse-engineering private Frameworks under MacOS X.

We present an analysis of Apple's proprietary disk encryption technology, FileVault. Besides the vendor's claim of 128-bit security through the use of AES, not much was previously known about its inner workings. This talk will fill in the many missing details in the puzzle and analyse the design decisions.

Besides the cryptographic details, this talk will of show how the relevant parts of the DiskImages framework were reverse-engineered for this project.
