Everybody Needs A Number

Published by gringod at 5:15 pm under General

As I previously blogged, the AACS-LA has a 128bit hex number that they call their own, and nobody else can use it without their expressed permission. If anyone does use it then the AACS-LA can use the power of the DMCA to stop its use and sue the people that used it, if they so wish. What gives the AACS-LA the rights to do this is that the number is used for the encryption of data (on HD-DVD and Blueray discs).

Well, the AACS-LA is are not the only people that can do this. The kind souls over at Freedom-To-Tinker have provided a free and quick service that allows anyone to get their own 128bit hex number which they can then issue DMCA take-down notices for. The reason you can use the DMCA to protect your number is:

First, we generate a fresh pseudo-random integer, just for you. Then we use your integer to encrypt a copyrighted haiku, thereby transforming your integer into a circumvention device capable of decrypting the haiku without your permission. We then give you all of our rights to decrypt the haiku using your integer. The DMCA does the rest.

My number is:

F2 97 9B 8F C5 C7 1B 66 F7 8E C9 3A 8C D4 C4 73

Phrixus has also claimed his number. Are you going to get yours?

    16 hex pairs… representing 8 bits per pair… 16×8 = 64 bit.
