List and describe the interacting services of the Kerberos system.

What will be an ideal response?

Kerberos consists of three interacting services, all of which use a database library:1. Authentication server (AS), which is a Kerberos server that authenticates clients and servers.2. Key Distribution Center (KDC), which generates and issues session keys.3. Kerberos ticket granting service (TGS), which provides tickets to clients who request services. In Kerberos a ticket is an identification card for a particular client that verifies to the server that the client is requesting services and that the client is a valid member of the Kerberos system and therefore authorized to receive services. The ticket consists of the client's name and network address, a ticket validation starting and ending time, and the session key, all encrypted in the private key of the server from which the client is requesting services.
