Explanation
Internet Key Exchange (IKE) is a protocol used by IPSec to negotiate and establish Security Associations (SAs), and is not a component of PKI. PKI components include Certificate Authorities (CAs), Registration Authorities (RAs), certificate repositories (B), certificate revocation mechanisms such as CRLs and OCSP (C), and timestamping services (A) for proving when a certificate or signature was valid. IKE may use PKI certificates during its authentication phase, but it is not part of the PKI framework itself.
