The NLS seems very against the idea of allowing any device aside
from
dedicated players to play the content.
Here's why:
The NLS's authorization system is completely dependent on a
handful of
secret decryption keys. The algorithms and procedures are
completely
open, and the algorithms themselves are industry standard, open
source
techniques. This is actually the best way to implement a crypto
system
- you don't want any of the security to be by obscurity.
however, what we're dealing with is a DRM system. The downfall
of any
DRM system is the very fact that there must be a way for hte
content
to be decrypted by a legal user. Take DVD players for example.
The
content on the discs is encrypted so cannot be easily copied.
However,
your DVD player must have the decryption keys inside of it in
order to
be able to decrypt the content for legal playback. If your
player did
not have the keys, the content would be secure - against
everyone,
including the legal users!
To make matters worse, allowing DRM decryption on a standard PC
(like
with DVD playback software and so on) opens up the gate for
millions
and millions of hackers to tear into the code, disassembling it,
studying it, and inevitably gathering the necessary decryption
keys.
Armed with these keys, a user then need only apply them to the
encrypted content to retrieve the completely unprotected data
