Which of the following is a PRIMARY purpose of using digital signatures?

The correct answer is C. Protecting data from unauthorized modification. Digital signatures primarily provide integrity (detecting unauthorized changes) and non-repudiation (proving the sender cannot deny sending the message). They use asymmetric cryptography where the sender signs with a private key and the recipient verifies with the public key…

Explanation

Digital signatures primarily provide integrity (detecting unauthorized changes) and non-repudiation (proving the sender cannot deny sending the message). They use asymmetric cryptography where the sender signs with a private key and the recipient verifies with the public key. They do not encrypt data for confidentiality, are not used for password storage, and authentication of a user accessing a system is a secondary function compared to integrity assurance.
