Question

Quizplus · Accepted Answer

Symmetric key cryptography uses the same secret key for both encryption and decryption, hence it is also known as secret key cryptography. Public key cryptography (option A) uses two different keys - public key for encryption and private key for decryption. PGP (option C) stands for Pretty Good Privacy, a type of software/protocol that uses both symmetric and asymmetric cryptography. PKI (option D) stands for Public Key Infrastructure, which involves the use of digital certificates and public key cryptography for secure communication.
