Correct answer: B
Correct matching: Digital Signature → Confirms authenticity and integrity; Hash Function → Produces a fixed-size digest; AES → Symmetric encryption algorithm; RSA → Asymmetric encryption algorithm.
Digital Signature: Confirms authenticity and integrity. A digital signature uses asymmetric keys to verify the sender and ensure the message was not altered.
Hash Function: Produces a fixed-size digest. Hashes map variable-length input to a fixed-size output used for integrity checks.
AES: Symmetric encryption algorithm. AES uses the same secret key for encryption and decryption.
RSA: Asymmetric encryption algorithm. RSA uses a public/private key pair for encryption and signature operations.
