5.5. Explain core concepts of public key cryptography.
Public key cryptography is technically a subset of asymmetric cryptography. Furthermore, PKI (Public Key Infrastructure) is a framework for deploying asymmetric (or public key) cryptography, along with symmetric cryptography, hashing, and certificates, to obtain a real-world flexible and functional secure communications system. The following sections discuss various aspects of PKI and its sub-elements (rather than focusing only on public key cryptography).
5.5.1. Public Key Infrastructure (PKI)
Public Key Infrastructure (PKI) isn't a product; rather, it's a blueprint or concept for a solution. It dictates what should happen and which standards to comply with, but it doesn't indicate which ...
