Textbook Problem

Encryption Use the encrypting congruence c ≡ ( 3 p + 2 ) mod 26 to code the message TOWER OF LONDON.

To determine

Use the encrypting congruence c(3p+2)mod26 to code the message “TOWER OF LONDON”

Explanation

Given: The message is “TOWER OF LONDON” and the congruence for encrypting is c(3p+2)mod26

Calculation:

The word in plaintext is given as

TOWER OF LONDON

Congruence is c(3p+2)mod26

Encryption is carried as follows

T  c=(60+2)mod26=62mod26=10   Coded as J

O  c=(45+2)mod26=47mod26=21   Coded as U

W  c=(69+2)mod26=71mod26=19   Coded as S

E  c=(15+2)mod26=17mod
