One of the major roles of public-key encryption is to address the problem of key distribution.

Question

Quizplus · Accepted Answer

Public-key encryption, also known as asymmetric encryption, uses two different keys for encryption and decryption: a public key, which is shared openly, and a private key, which is kept secret. This approach effectively addresses the problem of key distribution by eliminating the need to securely share a single, secret key between communicating parties, as is necessary with symmetric encryption. Instead, anyone can encrypt a message using the recipient's public key, but only the recipient can decrypt it using their private key.
