CompTIA CASP+ (CAS-004) — Question 496

A company wants to prevent a partner company from denying agreement to a transaction. Which of the following is the best solution for the company?

Answer options

• A. Federation
• B. Key escrow
• C. Salting hashes
• D. Digital signatures

Correct answer: D

Explanation

Digital signatures provide a way to verify the authenticity and integrity of a message or document, ensuring that the partner cannot deny their participation in a transaction. The other options, such as federation and key escrow, do not specifically address the issue of non-repudiation, while salting hashes is mainly a security measure for passwords.
