Basics of Cryptology – Part 8 (Modern Cryptanalysis of Classical Ciphers – Hill Climbing)

#cryptology, #cryptography, #cryptanalysis, #lecture, #course, #tutorial In this video, we show the basics of cryptology (cryptology = cryptography and cryptanalysis). This video here shows how hill climbing can be used to break classical ciphers. Compared to brute-force attacks, hill-climbing based attacks reduce the search space drastically, but do not find the correct key every time. We give a short introduction to what heuristics are. Then, we discuss in detail how the hill climbing algorithm works. Finally, we show different optimized solvers for classical ciphers, which internally all use hill climbing (or modified versions of hill climbing).
