Modern Cryptanalysis of Classical Ciphers Using Genetic Algorithms 🧬

#cryptology, #cryptography, #cryptanalysis, #lecture, #course, #tutorial In this video, we show the basics of cryptology (cryptology = cryptography and cryptanalysis). This video here shows how the genetic algorithm can be used to break classical ciphers. Compared to brute-force attacks, genetic algorithm-based attacks reduce the search space drastically, but do not find the correct key every time. We discuss how the genetic algorithm algorithm works for cryptanalyzing columnar transposition ciphers. Finally, we show different solvers for classical ciphers, which internally use the genetic algorithm, implemented in CrypTool 2.
