Question

Quizplus · Accepted Answer

Public key encryption, also known as asymmetric encryption, uses a pair of keys - one for encryption and the other for decryption. The two keys are mathematically related, but it is practically impossible to determine the decryption key from the encryption key. This allows for secure communication without the sender and receiver needing to previously exchange a secret key, as is required in symmetric encryption.
