Kasiski examination

ID: kasiski-examination

Kasiski examination is a method used in cryptanalysis to break classical ciphers, particularly polyalphabetic ciphers like the Vigenère cipher. It was developed by Friedrich Kasiski in the 19th century. The basic idea behind the Kasiski examination is to find repeated sequences of letters in the ciphertext and to analyze the distances between these repetitions.
