Fascinating article at the NSA site about the heroic efforts to provide long-distance secure voice communications over radio.
The good folks at Bell Labs essentially invented digitized, compressed voice, and encrypted it using synchronized pairs of records of random data at each end. Each terminal site had 55 *tons* of equipment!
Apparently this astounding - and apparently successful - effort was mostly declassified back in '76, but I first heard about it in Stevenson's Cryptonomicon last year.
There's an exhibit on this system in the War Room museum in London. --Steve Bellovin, http://www.research.att.com/~smb

There's also one at the NSA museum in Fort Meade. Thanks! Bill Bill Stewart, bill.stewart@pobox.com PGP Fingerprint D454 E202 CBC8 40BF 3C85 B884 0ABE 4639

Why do I have this feeling that both statements are true? Reminds me of the Iran Contra hearings where they had "country number one" and so on. (Meanwhile, in the background, the Pacifica announcer in a golf announcer-type voice is saying things like "and because of <some foriegn paper publication>, country number one is Saudi Arabia".) Just because something is sitting in a museum on public display does not mean its not classified! alan@ctrl-alt-del.com | Note to AOL users: for a quick shortcut to reply Alan Olsen | to my mail, just hit the ctrl, alt and del keys.
