Question

Quizplus · Accepted Answer

In symmetric key encryption, a single encryption key is used to both encrypt and decrypt the message. This means that the sender and receiver share the same key, which must be kept secret. This method is efficient for encrypting large amounts of data, but it requires a secure method of key exchange between the sender and receiver. SSL, public key encryption, and private key encryption all use different methods for key exchange and do not rely on a single shared key.
