Key distribution centers hold account databases and global catalogs, using cryptography to reduce the risk of exchanging keys. They operate using Kerberos for secure authentication methods and ensure user authorization. The system exhibits scalability but is prone to failure under certain conditions.
Domain services that use directories to hold account databases and global catalogs are called key distribution centers. In addition to holding these databases and catalogs, a key distribution center uses them to reference key distribution centers in other domains. The key distribution center idea is based on cryptography and is used in the security of computer networks. The cryptography used in these centers is a system of secret codes that reduces the risk of exchanging keys, which are a form of encrypted information, and controls the functioning of an algorithm. Often, this type of center operates within a system that allows access to a limited number of users or allows users access within limited times.
A key distribution center operates using Kerberos, which is a protocol for network authentication. These centers ensure secure authentication methods when making requests for services on a computer network. Typically, the distribution center works as follows: a user requests access to particular services within a computer network, and the distribution center uses encrypted techniques to authenticate that the user making the request is who they claim to be. The first request is sent to the server, which prompts the user to authenticate. Upon completion of this request, the request is then sent to a ticket-granting server.
In addition, the key distribution center verifies that the user has authorization to access the requested service. The server granting authorization, or ticket, sends a response to the user requesting authorization codes. On a successful login request, the user is granted permission by the distribution center, which is issued from the server key to allow the user login. The user then uses the permission granted to him and sends a request to a particular application server for the ability to access a particular service. Once this is done, the server sends a response back to the user, identifying itself and informing the user that it is the specific server they requested.
The benefit of using a key distribution center is that it can exhibit scalability, the ability of the system to handle increasing amounts of work operations smoothly, and the ability of that system to grow and adapt as it grows. It is not, however, a perfect system and is prone to failure under certain conditions. The system, however, is designed to have minimal failure with success rates up to 99.999%.
