Cryptography Stagnation During WW1
Today I continued reading the Code Book, and learned about the evolution(or lack thereof) of ciphers in World War 1.
In the late 1800s, around the time of the Crimean War, the Babbage-Kasiski method had rendered the Vignere cipher obsolete. After that, cryptography began to stagnate. New ciphers were still devised, but none could match the Vignere cipher or modern-day cryptoanalysis.
