D) secret key

Question

Quizplus · Accepted Answer

A digital signature is created by using a secure hash function to generate a hash value for a message, and then encrypting the hash code with a private key. This ensures that the message was not tampered with during transmission and that the sender of the message is authentic. A keystream is used in symmetric-key cryptography, a one-way hash function generates a fixed-size output from an input message, and a secret key is used in both symmetric and asymmetric-key cryptography.
