Hill cypher in python
WebMar 20, 2024 · Vigenere Cipher is a method of encrypting alphabetic text. It uses a simple form of polyalphabetic substitution. A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The encryption of the original text is done using the Vigenère square or Vigenère table. WebKnown plaintext attack on Hill's Cipher 🔗 Recall that when we encipher a message using Hill's Cipher we use either the equation: Cipher≡ m⋅M essage or Cipher≡ m⋅M essage+s. C i p h e r ≡ m ⋅ M e s s a g e or C i p h e r ≡ m ⋅ M e s s a g e + s. 🔗 Solving these for the ciphertext we got the equations:
