- Encryption keys known to the security principal and KDC
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.
