Riverbank Labs trained three classes of Army officers in the fields of cryptology and cryptanalysis
by early 1918, at which time MI-8, the Code and Cipher Section of the MID, established its own training.
During the World War II, Alan Turing was heading a team responsible for German naval cryptanalysis
. He cracked the German Enigma secret ciphers using a number of techniques.
Turing's utility as the brains of an important part of the wartime British cryptanalysis
operation run out of Bletchley Park kept him on the government's payroll and out of the hands of the law during the war.
After a cryptanalysis
phase ranging over 4 years, stream ciphers were filtered in 3 phases by their performance and security.
22 shows that encrypting message signal with two hyper-chaotic signals makes the encryption stronger, hence not easily broken by power spectrum analysis and low pass filter method of cryptanalysis
