But also many messages like "attacked by aircraft", "attacked by aircraft , sinking". Sent at the same time as the attack - easy crib material surely.<br /><br />Slightly unrelated, Venona. Interesteing that a one time pad system, even with computer attacks, massive resources and time and benefit of using some of the pads more than once, only a small % of materiel was decrypted.<br /><br />One time pad system better than a machine for fairly short messages.bcf1https://www.blogger.com/profile/12133237051104180211noreply@blogger.comtag:blogger.com,1999:blog-3335175720102608134.post-62104124818146755462016-05-14T00:30:16.187-07:002016-05-14T00:30:16.187-07:00Hi Christos

I see Bonatz in ca 1968 (after publication of a book on enigma by one of the poles) said he thought it was impossible for them to have broken enigma. I wonder why he said that? One assumes he knew of Wicher background.<br /><br />On the other hand I see that immediate post war interviews revealed that many of the (non naval officer ) crypto personnel had long felt that enigma was not secure - eg Tranow.bcf1https://www.blogger.com/profile/12133237051104180211noreply@blogger.comtag:blogger.com,1999:blog-3335175720102608134.post-22072924876380750722016-05-08T23:48:01.045-07:002016-05-08T23:48:01.045-07:00Yes but it also helped radio operators when some o...Yes but it also helped radio operators when some of the letters when not received correctly.

I mean, surely any mathematical crypto types would have advised against itbcf1https://www.blogger.com/profile/12133237051104180211noreply@blogger.com
