Network Security: Polyalphabetic Cipher (Vigenère Cipher)
Topics discussed:
1) Classical encryption techniques and introduction to polyalphabetic substitution cipher.
2) Comparison of mono-alphabetic substitution cipher with a polyalphabetic substitution cipher.
3) Working of Vigenere cipher with an example.
4) Cryptanalysis on Vigenere Cipher: Repeating keys and frequency distribution of key and plaintext.
5) Need for auto-key system and effect of auto-key system on Vigenere cipher to improve the security of Vigenere cipher with an example.
