Cryptography 4. Consider a transposition cipher that needs to encrypt a message of length 15 using [3, 1, 4, 5, 2] as the key. a) (5 pts) Show the process of encryption using the matrix representation of the key. You may pick any message of length 15 as your choice. b) (5 pts) Repeat Part (a) for the process of decryption. The output of the decryption should be the original message.

Using a substitution cipher that skips by 7 characters, encrypt the message COMPUTERSCIENCE4ALL. For the input alphabet use 26 uppercase letters followed by 10 digits numbered 0 through 9. I have encrypted an English phrase using a substitution cipher that has an input alphabet of 26 uppercase letters. My cipher has skipped by N letters. You may assume that the most common letters in the English language are E T A O I N Sentence: LJWRPDNBBCQNARPQCJWBNA
