312-50V10 · Question #175

What is the difference between the AES and RSA algorithms?

The correct answer is D. RSA is asymmetric, which is used to create a public/private key pair; AES is symmetric, which is. AES is a symmetric algorithm using a single shared key, while RSA is an asymmetric algorithm using a mathematically linked public/private key pair - they represent the two primary categories of modern encryption.

Why each option

AES is a symmetric algorithm using a single shared key, while RSA is an asymmetric algorithm using a mathematically linked public/private key pair - they represent the two primary categories of modern encryption.

ABoth are symmetric algorithms, but AES uses 256-bit keys

RSA is not a symmetric algorithm - it is asymmetric and uses a key pair, not a single shared key, so this statement is fundamentally incorrect.

BAES is asymmetric, which is used to create a public/private key pair; RSA is symmetric, which is

AES and RSA are reversed in this choice - AES is the symmetric algorithm and RSA is the asymmetric one, not the other way around.

CBoth are asymmetric algorithms, but RSA uses 1024-bit keys

AES is not an asymmetric algorithm - it is a symmetric block cipher that uses a single key, so describing both AES and RSA as asymmetric is factually incorrect.

DRSA is asymmetric, which is used to create a public/private key pair; AES is symmetric, which isCorrect

RSA is an asymmetric algorithm that uses a public/private key pair, where data encrypted with the public key can only be decrypted with the private key, making it suitable for key exchange and digital signatures. AES is a symmetric block cipher that uses a single shared secret key for both encryption and decryption, making it faster and efficient for bulk data encryption.
