About :

The Vigenère encryption was invented in the 16th century to encrypt ciphertexts. For a long time, it was considered a secure method and unbreakable. In 1863, however, the Prussian infantry major Friedrich Wilhelm Kasiski published a method to determine the key length used in encryption. This made the Vigenère encryption vulnerable. The video uses an example to show how the Kasiski test is carried out and what other attack options there are to break the ciphertext. 0:00 History 0:30 Kasiski test 1:57 Grouping ciphertext into columns 2:10 Frequency analysis 3:25 Analysis of the multiple-occurring text snippets 4:08 Brute force plaintext attack 6:02 Context-dependent plaintext attack 6:49 Ciphertext cracked 7:20 Conclusion 7:37 Vulnerabilities 8:00 Security measures
