WebQuestion: 3. RECOGNIZING & BREAKING CIPHERS FOR DIFFERENT TEXTS ENCRYPTED USING DIFFERENT CIPHERS (30% Points) Please find 6 ciphertexts of different messages encrypted using the following 6 classical ciphers available in CrypTool: Caesar (shift cipher with k=3), Vigenere. Hill (with d=3), Affine, Playfair, and Permutation. 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.
