In this video, I explain the Lorenz SZ42, a ciphermachine used by the Germans during WWII. It was used for encryption of high-level communications beginning in mid 1942. The machine encrypts Baudot code using a pseudo-random generated keystream.
In the video, I explain how the cipher machine works and we analyze its keyspace size and unicity distance. We also create a workspace in CrypTool 2 to encrypt and decrypt text using the new SZ42 component.
If you are interested in learning the fundaments of cryptology, let me invite you to have a look at our video series about the basics of cryptology, also for beginners: • Basics of Cryptology -...
