The validation process is designed to ensure that the client is using the correct session key and that the time stamp is valid. The session ticket includes two copies of a session key that the client will use to access the requested resource. The first copy of the session key is encrypted using the client's session key.

The second copy of the session key contains the user's access information and is encrypted with the resource's secret key known only by the KDC server and the network resource. If this is successful, the network resource has validated that the session ticket came from a trusted KDC. It then decrypts the user's access information, using the session key, and checks the user's access permissions.

The time stamp sent from the client is also decrypted and validated by the network resource. The next time the user needs to access the resource, the session ticket in cache is used, as long as it hasn't expired.

Using a cached session ticket allows the client to send a request directly to the network resource. If the ticket has expired, however, the client must start over and get a new ticket.
