Exposing and Exploiting AACSv2 UHD DRM - Full AACSess

Explore the vulnerabilities and inner workings of AACSv2 DRM in this conference talk from the 37th Chaos Communication Congress. Delve into the history of AACS, practical side-channel attacks against Intel SGX secure enclave technology, and the first full compromise of AACSv2. Learn about the Advanced Access Content System (AACS) DRM scheme, its evolution from AACSv1 to AACSv2, and the security measures implemented for 4K UHD Blu-ray discs. Discover how hardware side-channel attacks can undermine SGX guarantees, and witness the first public description of AACSv2's key derivation process, revocation mechanisms, and traitor-tracing features. Examine the implications of BIOS updates from multiple motherboard vendors on SGX security, and observe a groundbreaking demonstration of UHD Blu-ray disc decryption and playback on an unofficial platform.
