The above attack shows that this kind of transformation is easy to break if enough pairs of plaintexts and ciphertexts are known. Modern ciphers, in fact, always contain a non-linear component to prevent this kind of attacks. Menu Home Projects Teaching

WebRecall 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: M essage = m−1Cipher or M essage = m−1Cipher+(−m−1s). here
