Assignment:

Using the English alphabet (i.e., mod 26 arithmetic) let plaintext = (p1, p2, pn,) and corresponding cipher text = (c1, c2, cn).

Suppose the encryption function is ci = (pi + 8) (mod 26).

You receive the cipher text message: IUMZQKI QA I LMUWKZIKG

What type of cipher is this?
What is the decryption function, and the decrypted/recovered plaintext,
Show each and every step.
