Sidney Dang,Derek Vigon,Jaleel Abdul-Adilerman machine-cipher known in Bletchley as “FISH”. The network using this system grew to have many links and each link was given the name of a kind of fish. Thus the first link to be intercepted was called “Tunny” and I recall such names as “Bream”, “Herring” and “Mackerel” for later links.

“I Do Not Need Help to Define Myself”lso called Tunny by Bletchley Park (BP), the Siemens . (SFM) T52, and the one-time-tape machine T43, also manufactured by Siemens. The Lorenz machines, which existed in three different models, SZ40, SZ42a, and SZ42b, are well known as the machines that were broken at BP with the aid of Colossus. The

In the second half we will design algorithms for computing roots of polynomials over the function field of a nonsingular absolutely irredu
