Question

A digital signature

a) Is the computer digest of the sender's digital certificate.

b) Allows digital messages to be sent over an analog telephone line.

c) Is the encrypted mathematical value of the message sender's name.

d) Is derived from the digest of a document that has been encrypted with the sender's public key.

e) None of these.

Answer 1

A digital signature is created by encrypting a document's hash with the sender's private key, and it is related to binary code and transistors in electronics.

Step-by-step explanation:

The correct answer to the question, 'Which of the following is true about a digital signature?' is d) Is derived from the digest of a document that has been encrypted with the sender's public key. A digital signature is a type of electronic signature that ensures the authenticity and integrity of a message or document.

This signature is created when a document is hashed, and that digest is then encrypted with the sender's private key. In terms of digital communication, both digital signatures and digital data (including digital signatures) make use of binary code in the form of sequences of ones and zeros, which are handled by transistors and integrated circuits in electronic devices.
