PKI - Public Key Infrastructure

PKI consists of a set of roles, hardware, software, policies, processes, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates and manage public-key encryption. 


PKI is the foundation for Secure Socket Layer (SSL) and Transport Layer Security (TLS) which protect and authenticate traffic over the internet and is a system of encryption that authenticates and secures communications between two systems. It establishes the trusted business environment for applications such as digital signatures (e-Signatures), e-Commerce, and is increasingly being utilized to secure IoT. Some experts say blockchain could become competitive with PKI.
