WebCryptanalysis of the Vigenere cipher has 2 main steps: identify the period of the cipher (the length of the key), then find the specific key. To identify the period we use a test based on the Index of Coincidence, to find the specific key we use the Chi-squared statistic. WebLa cryptanalyse est la technique qui consiste à déduire un texte en clair d’un texte chiffré sans posséder la clé de chiffrement. Le processus par lequel on tente de comprendre un …
