WebOct 10, 2024 · The public key infrastructure or PKI is a data security architecture which is based on cryptography, a branch of applied mathematics. Unlike other earlier systems, it uses a pair of keys, one public and available freely to end users on the network, and another secret or private key that is known only to its owner. WebThe Public key infrastructure (PKI) is the set of hardware, software, policies, processes, and procedures required to create, manage, distribute, use, store, and revoke digital certificates and public-keys. PKIs are the foundation that enables the use of technologies, such as digital signatures and encryption, across large user populations.
