Vernam vs Caesar cipher
The vernam cipher is always a more secure option than the caesar cipher.
- The vernam cipher, if implemented correctly, is mathematically unbreakable. The caesar cipher can easily be cracked.
- We can use statistical analysis of letter frequencies to crack the caesar cipher, but not the vernam cipher.
- vernam cipher doesn’t encrypt the same plaintext letter as the same ciphertext, so no repeating pattern.
