CompTIA Security+ (SY0-601) — Question 778

Business partners are working on a security mechanism to validate transactions securely. The requirement is for one company to be responsible for deploying a trusted solution that will register and issue artifacts used to sign, encrypt, and decrypt transaction files. Which of the following is the BEST solution to adopt?

Answer options

• A. PKI
• B. Blockchain
• C. SAML
• D. OAuth

Correct answer: A

Explanation

The correct answer is PKI (Public Key Infrastructure) because it provides a framework for managing digital certificates and public-key encryption, which are essential for signing and encrypting transaction files securely. Blockchain, while secure and decentralized, does not specifically address the management of digital certificates. SAML (Security Assertion Markup Language) and OAuth are primarily used for authentication and authorization, not for the management of artifacts used in cryptographic processes.
