- KDC Key Distribution Center is a service that runs on a physical security server. The KDC maintains a database of all security principal account information in the realm (equivalent to a domain in Windows).
- Along with other information for each security principal, the KDC stores encryption keys known only to the security principal and the KDC. This key is also called a long-term key and is used to exchange between the security principal and the KDC. In most implementation protocols, the long-term key is regenerated from the user login password.
- When the KDC distributes the keys, both hosts communicating need to apply for a session key from the KDC, and the host communicates with the KDC using a permanent session key shared by both.
