What is PKI (Public-Key Infrastructure)?
✍: FYIcenter.com
Public-Key Infrastructure (PKI) is a public-key cryptography system
that enables users to securely communicate on an insecure public network,
and reliably verify the identity of a user via digital signatures.
The main function of the a PKI system is for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository, and revokes them if needed.
A PKI system usually consists of:
- A certificate authority (CA) that both issues and verifies the digital certificates.
- A registration authority which verifies the identity of users requesting information from the CA
- A central directory, i.e. a secure location in which to store and index keys.
- A certificate management system
