AACS Cracked — That didn’t take long.
This piece from Engadget is reporting how a hacker broke AACS, the encryption that is used by both Blue Ray and HD-DVD.
AACS DRM cracked by BackupHDDVD tool? - Engadget
Can it be? Is Hollywood’s new DRM posterchild AACS (Advanced Access Content System, see more here) actually quite breakable? According to a post on our favoritest of forums (Doom9) by DRM hacker du jour muslix64, his new BackupHDDVD tool decrypts and dismantles AACS on a Windows PC. Just feed the small utility a crypto key.
I am hardly a rocket scientist, especially when it comes to cryptography, but how can any REAL copy protection be achieved, Assuming that every Blue-Ray or HD-DVD player has to decrypt every disc that it plays, The key(s) for the media has to be found somewhere on the disc or every possible key has to hardcoded somewhere in the player. Either way its like writing your PIN on the back of your ATM card. Like any cryptographic system, the vulnerability is not the cryptography but how to deliver keys in a secure way.
