What is Public Key Infrastructure (PKI) and How Does It Work?
PKI (Public Key Infrastructure) is a system of processes, technologies, and policies that governs the asymmetric encryption of data. It governs the issuance of PKI-based certificates which in turn safeguards sensitive data and provides identity assurance and access management in the digital ecosystem. In a nutshell, PKI technology directs everything that encompasses asymmetric encryption to ensure end-to-end security and integrity in the digital ecosystem.
As a part of PKI implementation, and asymmetric keys are issued which act as the cornerstone of this technology. These PKI-based certificates are akin to a driver's license or any other identity proof for the digital world. Consequently, PKI may refer to any software, policy, process, or procedure that may be employed while configuring and managing those certificates and keys.
Some of the most common examples of PKI implementation can be found in , , Code Signer Certificates, , and authentication for Internet of Things (IoT) devices.
