Answer 1

Answer #1

1. The correct answer is a.

Hill Cipher uses Matrix theory for multiplication and inverse of matrices.

2. The correct answer is d.

In Monoalphabetic cipher, every alphabet is replaced by a fixed cipher alphabet. In Polylaphabetic cipher, each alphabet is replaced by different cipher alphabet that resembles my Monoalphabetic substitutions.
