What does PKI ensure through technology and process?

• A. Integrity of digital credentials
• B. Network speed
• C. Employee productivity
• D. Facility security

Answer: (A)

Public Key Infrastructure (PKI) creates trust in digital identities by managing keys, certificates, and the processes that govern them. It binds a public key to an identity through digital certificates issued by trusted authorities, and it uses digital signatures to ensure that the certificate and the data it protects haven’t been altered. This combination provides integrity: you can verify that a credential or message came from the claimed source and has not been tampered with, thanks to the verifiable chain of trust and the ability to check certificate validity and revocation. PKI’s scope is about identity validation, data integrity, and trust in digital exchanges, not about increasing network speed, boosting productivity, or securing physical facilities. So the focus of PKI is ensuring the integrity of digital credentials.
