Public Key Infrastructure (PKI)

It is integrated system of software, encryption methodologies, protocols, legal agreements, and 3rd-party services enabling users to communicate securely.
PKI systems are based on public key cryptosystems which includes digital certificates and certificate authorities (CAs).
PKI protects information assets in many ways. They are given below:
-Authentication
-Integrity
-Privacy
-Authorization
