迷人历史
Mathematicians and cryptanalysts, such as Alan Turing, were recruited to help at a secret facility in the town of Bletchley, England. As war broke out in Europe, Turing designed and built a machine – called " Colossus" – to crack several complex codes.
Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to loosen" or "to untie") is the study of analyzing information systems in order to study the hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
