Title:
METHOD AND APPARATUS FOR PROVIDING A KEY DISTRIBUTION CENTER
Document Type and Number:
WIPO Patent Application WO2002033884
Kind Code:
A3
Abstract:
One embodiment of the present invention provides a system for operating a key distribution center (KDC) that provides keys to facilitate secure communications between clients and servers across a computer network, wherein the system operates without having to store long-term server secrets. The system operates by receiving a communication from a server at the KDC. This communication includes an identifier for the server, as well as a temporary secret key to be used in communications between a client and the server for a limited time period. In response the communication, the system attempts to authenticate the server. If the server is successfully authenticated, the system stores the temporary secret key at the KDC, so that the temporary secret key can be subsequently used to facilitate communications with the server.
