from Wikipedia, the free encyclopedia

Ralph Erskine is a historian and cryptologist .

Act

Ralph Erskine deals with classical cryptology up to encryption methods of the Second World War . He is particularly interested in cryptanalysis , i.e. methods for breaking encryption and the associated historical effects.

In particular, he deals with the Enigma rotor key machine used in communications by the German military during World War II , as well as with the methods and machines used to break it, such as the Turing bomb , and the resulting historical consequences.

In 2000 he was awarded the special title of Visiting Research Scholar by the Bletchley Park Trust of Bletchley Park , the agency in the United Kingdom that successfully deciphered the secret communications of the German Wehrmacht during World War II and is now a museum. He received this honor at the same time as Frode Weierud and David Hamer .

In 2002 Ralph Erskine gave the Gauß lecture of the German Mathematicians Association (DMV). He is a member of the Crypto Simulation Group (CSG) .

Hugh Sebag-Montefiore described Ralph Erskine as "the leading expert of Naval Enigma" (German: "the leading expert for the Naval Enigma ").

Ralph Erskine is a retired attorney and lives in the Northern Irish capital Belfast .
