KDC in Kerberos: Central Authentication Hub

A Key Distribution Center (KDC) is a central component in the Kerberos authentication protocol, responsible for securely distributing authentication keys and managing the authentication process between clients and servers in a network. The KDC facilitates secure and efficient communication by issuing cryptographic tickets that allow users to access network services without continuously re-entering their credentials.

Understanding the Key Distribution Center (KDC) is relevant for the Security+ exam, particularly in the context of authentication protocols and secure communication.
