What is PKI?

Public Key Infrastructure (PKI) refers to the technical mechanisms, procedures and policies that collectively provide a framework for addressing the previously illustrated fundamentals of security - authentication, confidentiality, integrity, non-repudiation and access control.

PKI enables people and businesses to utilise a number of secure Internet applications. For example, secure and legally binding emails and Internet based transactions, and services delivery can all be achieved through the use of PKI.

PKI utilises two core elements; Public Key Cryptography and Certification Authorities.
