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.

"WebFor the Vigenère cipher, cancellation occurs whenever i − j is a multiple of the key length ℓ, producing a characteristic comb-shaped autocorrelation plot. For an autokey cipher, however, cancellation only occurs when i − j exactly equals the key length, resulting in just a single peak. It works with autokey system because the key itself ...
