Use the encryption matrix A=[0110] on the one-wordmessage: "breakfasts". Describe simply in words what thisparticular encryption does.
For next problems you will need to use M=[11−251].
Show that M is a valid encryption matrix and find itsdecryption matrix, N. The entries of N should bebetween −25 and 25. In other words, generally reducethe entries, but if you get a large value like 24, feel freeto shift it to −2.
Use M and N to encrypt and then decrypt themessage:
"Larger matrices are better."
Pad the last letter if necessary. Use only a single matrix forthe message plaintext/ciphertext, as in the notes.
