PBS will be airing a Nova program next Tuesday, 9 Nov, called "Decoding Nazi Secrets". It includes material from the popular British series "Station X", about the work of Bletchley Park in breaking German ciphers. The related web page is http://www.pbs.org/wgbh/nova/decoding/ I prepared a cipher contest for them with a flavor of WW2 hand ciphers, partly inspired by "Between Silk and Cyanide", and partly by some research I did in NSA's "Open Door" materials last month at the National Archives. Solve one of the ciphers and you're in the pool to win stuff, but nobody can win for more than one cipher. There's a two-week time frame. I won't be able to discuss attacks and solutions until after the contest ends, but do send in your solutions and explanations, and Nova will forward them on to me for checking. -- Jim Gillogly 15 Blotmath S.R. 1999, 20:02 12.19.6.12.3, 4 Akbal 11 Zac, Ninth Lord of Night
