Initially the decryption was mainly of Luftwaffe (German air force) and a few Heer (German army) messages, as the Kriegsmarine (German navy) employed much more secure procedures for using Enigma. Alan Turing , a Cambridge University mathematician and logician, provided much of the original thinking that led to upgrading of the Polish ...
The Enigma machine was considered so secure that it was used to encipher the most top-secret messages. [1] The Enigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. In typical use, one person enters text on the Enigma's keyboard and another person writes down which of the 26 lights above the keyboard ...
For everyday consumers, the simplest way to send encrypted messages or make encrypted calls is to use communications apps like Signal or WhatsApp that have implemented end-to-end encryption ...
Cryptography was used extensively during World War II because of the importance of radio communication and the ease of radio interception.The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines.
The Germans themselves could be very accommodating in this regard. Whenever any of the turned German Double-Cross agents sent a message (written by the British) to their respective handlers, they frequently obligingly re-encrypted the message word for word on Enigma for onward transmission to Berlin.
The FBI is warning phone users to encrypt their text messages, especially if you send messages between Apple and Android users. The FBI and the Cybersecurity and Infrastructure Security Agency ...
To encrypt a message, the agent would select words from the poem as the key. Every poem code message commenced with an indicator group of five letters, whose position in the alphabet indicated which five words of an agent's poem would be used to encrypt the message. For instance, suppose the poem is the first stanza of Jabberwocky:
This is the symmetrical key Y", where X is a randomly generated identifier, and Y is a randomly generated secret key meant for symmetrical encryption. Hence, both X and Y are unique to each message. All the messages are encrypted in a way such that a user may conduct a brute force attack on each message with some difficulty.
