The concept of a public key infrastructure is quite complicated. It is basically a combination of hardware, software, policies, procedures and people which combined together manage a digital certificate. It is explained in some detail on Wikipedia.
Public Key Infrastructure (PKI) in an integrated system of software, encryption methodologies, protocols, legal agreements, and third-party services that enables users to communicate securely an protect information assets.

It stands for Public Key Infrastructure. It has to do with security and data encryption.
PKI or Public Key Infrastructure
certificate authority
One can receive a PKI certificate, or a public-key infrastructure certificate, is by digitally signing and publishing the public key bound to a given user.
PKI (Public-key Infrastructure)
Certificate Server (CS)
A user's private key is kept private and known only to the user. The user's public key is made available to others to use. The private key can be used to encrypt a signature that can be verified by anyone with the public key. Or the public key can be used to encrypt information that can only be decrypted by the possessor of the private key
Public Key Infrastructure (PKI) operates by using a combination of hardware, software, policies, and procedures to manage digital certificates and public-key encryption. It involves a trusted Certificate Authority (CA) that issues digital certificates to verify the identity of entities, allowing secure communication. Users generate a pair of keys: a public key, which is shared widely, and a private key, kept secret. PKI ensures the integrity, authentication, and non-repudiation of data through cryptographic techniques, enabling secure transactions over unsecured networks.
