| Question 889 |
An example of polyalphabetic substitution is
| P-box | |
| S-box | |
| Caesar cipher | |
| Vigenere cipher |
Question 889 Explanation:
A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case. The Enigma machine is more complex but is still fundamentally a polyalphabetic substitution cipher.
