L 23 - Comparison of Monoalphabetic and Polyalphabetic Substitution Cipher

In this video I have explained a detailed comparison on monoalphabetic and polyalphabetic substitution ciphers with example.

Monoalphabetic Cipher | Polyalphabetic cipher | Substitution cipher | one to one mapping | One to many mapping
