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).
