Yes but the NSA really wanted the Skipjack for DOD messsages.

As I recall, only for sensitive but unclassified data.

They (probably) monitor all of those anyway.

Tessera/Clipper had built-in GAK, so a backdoor would have been redundant.

But Matt did alot of work on his project but did he show how to brak Skipjack and does this totally trash the Fortezza program?

No. He showed that with a bit of work he could fake the ID of the chip sending the message. He did not 'break Skipjack' in any way. He did show that the protocol (which used Skipjack for bulk encryption) was incompetently designed. Get a spellchecker. Peter Trei trei@process.com
