Public key cryptography supports security mechanisms such as confidentiality, integrity, authentication, and non-repudiation. However, to successfully implement these security mechanisms, you must carefully plan an infrastructure to manage them. A public key infrastructure (PKI) is a foundation on which other applications, system, and network security components are built. A PKI is an essential component of an overall security strategy that must work in concert with other security mechanisms, business practices, and risk management efforts.

PKI is a broad subject matter and is constantly evolving to meet the growing demands of the business world. This article addresses PKI at a relatively high-level and does not include details regarding the underlying cryptography.
