Re: Patent / restriction on AES

[Shawn Masters]

	I can't comment on Europe, but NIST required that the chosen algorithm 
be made publicly available without license restriction.  As far as 
exportation from the US goes, a classification or exception are required 
before it can ship.

Which is the status of AES regarding intellectual property ?
The official Rijndael site says :
"Rijndael is available for free. You can use it for whatever purposes you
want, irrespective of whether it is accepted as AES or not. "
So I guess it is in the public domain.
But my questions are : 
- did the NIST set any restriction to the use of AES (especially about
exportation outside the US) ?

- are there legal restrictions regarding its *use* (mostly in Europe where
cryptographic material is controlled according to the length of the key
used) ?
Thank you in advance for any information
