Ah yes. I assume that when there WERE export restriction in the USA you
posted crypto on the web and let the DOJ know.

I note that there are STILL export restriction in the USA on cryptography.
HOw about emailing a copy of PGP to Iran to protest the US govenment's
rules? Or NOrth Korea?

And when you went to Russia, you posted crypto on the web there and let the
KGB know? It is all very well for you to advocate actions that will get
others thrown in jail.

Gevernments have ways of making you regret annoying them.

The key words you should be looking for are "inclusive" and "exclusive"

You are saying "Change your broken system and use my system instead". But
if they are changing already why not change to a system that is not broken
at all and gives strong authentication? Ie, your system falls between two
stools. It means that the people using it have to change anyway, but it
gives a system which is weak as a reward for all that work.

Dear all reading professional (as described in patent regulations),

This time, I write to you to in order to make sure that you aware of a
simple method that can be used in increasing the password security
within networked computer environment. This method is so simple that
you probably have already read about it, but let's just make sure that
third party instances will not be granted patents for this obvious and
only slightly innovative method.

Field of invention:
^^^^^^^^^^^^^^
Telecommunication systems, where a user is required to insert a
password in order to be able to use, one or more, access restricted
resources.

Dear ALL,

i need some encryption algorithm, that will produce the cipher text of
the same size as the input or plain text

any ideas?? can any of the AES modes do so??

You'll have to find the CSS specifications and/or ask a designer.

Failing that, track down one of the authors of libdvdread and ask them
if they know.

My guess is that each stream/title is encrypted independently, then as
they're collected to be published on a DVD the disc key encrypts all of
the title keys (of which there may be more than one) and the player
keys encrypt the disc key. Only really useful reason to have that many
levels of indirection.

For all intents and purposes CSS is as effective as XOR'ing the byte
0xAA against the stream. So unless the CSS developers were so off-base
as to think CSS was good, it's hard to really rationalize any of their
decisions (hint: most likely CSS was designed by commitee by a bunch of
sales/senior folk where at least one of them thought themselves the
devious cryptographer).
