Key Distribution Center (KDC)

A Key Distribution Center (KDC) is a trusted service that helps secure communication within a network. It manages and shares secret keys, which are like digital passwords, between users and systems. When someone wants to access a service, the KDC verifies their identity and provides a unique key that allows secure, encrypted communication. This process ensures that only authorized users can access sensitive information, preventing eavesdropping or unauthorized access. Essentially, the KDC is a central authority that simplifies key management and enhances security in network interactions.
