In PKI, a root certificate is a self-signed certificate that serves as the trust anchor and can issue certificates to intermediate CAs in a hierarchy. The term for this authority is

• A. Public Key Infrastructure
• B. Digital certificate
• C. Public Key Cryptography Standards
• D. Root Certificate Authority

Answer: (D)

In PKI, the trusted anchor in the certificate chain is the highest-level authority that signs certificates for other CAs and is itself self-signed. This root authority sits at the top of the hierarchy and distributes its public key so that all other certificates can ultimately link back to it. Because it signs certificates for intermediate CAs and serves as the ultimate trust anchor, the correct term for this authority is the Root Certificate Authority. The other items refer to the general PKI framework, individual certificates, or standards, not the topmost signing authority itself.
