WebPolygraphic Substitution Ciphers: The Hill cipher . The Playfair cipher is a polygraphic cipher; it enciphers more than one letter at a time. Recall that the Playfair cipher enciphers digraphs – two-letter blocks. An attack by frequency analysis would involve analyzing the frequencies of the . 26 26 676×= digraphs of plaintext. Complications ... WebAs always we need to start with frequency analysis, but if we assume the message used a Hill's cipher with a 2×2 2 × 2 matrix we will focus on bigrams. For the text above the bigrams frequencies are as follows: 🔗 Table 6.4.5. Bigrams from a message with 428 characters 🔗
