Cryptographical rotor machine
WebRotor Machines In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting messages. In the 1920s, various mechanical encryption devices were invented to automate the process of encryption.

WebApr 10, 2015 · This example is correct. The inversed versions are the inverse permutation; that is, if the forward direction is the permutation P, then the inverse permutation P − 1 has the property that P − 1 ( P ( X)) = X for all X. That is, if X is a plaintext letter, and we run it through in the forward direction (giving us P ( X) ), and then run it ... WebOct 8, 2016 · Rotor cipher A Rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting secret messages. A Stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher each plaintext digit is encrypted one at a time with the ...
WebIn 1921, Boris Hagelin developed his first cipher machine. Since then, he produced a wide range of machines, of which the M-209 (shown here) is probably the most well-known one. After WWII, the company (Crypto AG) developed numerous other machines and models, and is still in business today.
