Substitution techniques in cryptography
A) RSA
B) AES
C) Caesar Cipher
D) Diffie-Hellman
Answer:
C) Caesar Cipher
Explanation:
The Caesar Cipher is a classic example of a substitution technique in cryptography. It involves replacing each letter in the plaintext with a fixed number of positions down the alphabet. Options A and D refer to public-key cryptographic algorithms, while option B (AES) is an example of a symmetric-key encryption algorithm, not a substitution technique.
