The Siemens & Halske T52 (Geheimschreiber)
The Siemens & Halske T52 was a German encryption machine used during World War II. It was also known as the “Geheimschreiber” (“secret teleprinter”) and was designed to encrypt teleprinter communications. Unlike the more famous Enigma machine, which relied on wired rotors for encryption, the T52 generated a stream of zeros and ones that was added to the plaintext to create the encrypted message. This principle was closer to a stream cipher and represented a more advanced approach to cryptography at the time.
