What is PKI?
A Public Key Infrastructure (PKI) is a system of cryptographic technologies, standards, management processes, and controls governing the use of digital certificates.
PKI is a system for supporting digital signatures and document encryption for an organisation.
PKI is an enabling technology –Â it enables users of an insecure public network (such as the internet) to securely and privately exchange data through the use of a public/private cryptographic key pair that is obtained and shared through a trusted authority.
A PKI is made up of:
1. A Certificate Authority (CA) that issues and verifies digital certificates
2. A registration authority that acts as the verifier for the certificate authority before a digital certificate is issued to a requestor
3. One or more directories where the certificates or public keys are held
4. A Certificate Management System (CMS)
A successfully managed and implemented PKI assures:


Integrity

Non-Repudiation

Confidentiality

Authentication
The process of testing and verifying an assertion of identity, in order to establish a reliable level of confidence in those assertions.
