DRM vs. Reverse Engineering

Federico Biancuzzi intervjuar Nate Lawson som varit med och skrivit kopieringsskyddet till Blu-ray. Vi har även tidigare skrivit om DRM-attacker här.

Each time a new digital rights management (DRM) system is released, hackers are not far behind in cracking it. Reverse engineers have taken down the security protecting content encoded for Windows Media, iTunes, DVDs, and HD-DVDs.

Attacker mot DRM

 

Kryptogurun Nate Lawson gav en presentation (PDF) under konferensen RSA 2008 om hur du designar samt attackerar DRM system.

Nate jämför Blu-ray, AACS vs. BD+. Samt nämner lite om AACS MKBv7 som Slysoft tydligen knäckt:
