ABSTRACT:
A method for exchanging a secure slave key between an agent and a manager which are connected by an unsecured digital computer network. A master key is provided, which is known to both the manager and the agent. The manager sends a request for an unpredictable number across the digital computer network to the agent. The agent receives the request and generates the unpredictable number, which is sent back to the manager across the digital computer network. The manager receives the unpredictable number, and uses it and the master key to produce a slave key. The agent likewise uses the unpredictable number and the master key to produce the slave key. In this manner, identical slave keys have been produced at both of the manager and the agent sites, without having to send the slave key across the unsecured digital computer network.
