ElsieFour – A Low-Tech Cipher Inspired by RC 4
#cryptology, #cryptography, #cryptanalysis
In this video we explain how the low-tech cipher ElsieFour (LC4) works. It is a hand cipher inspired by RC4, Playfair, and the concept of plaintext-dependent key streams. In the video, we discuss how to encrypt text, compute the size of the key space, and compute the Unicity Distance. Finally, we use CrypTool 2 to encrypt and decrypt text with the ElsieFour component.
Specification of LC4: https://eprint.iacr.org/2017/339
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: https://youtu.be/jbumW7Ym03o
