Abstract
A digital 'baton' is provided from a firewall or other gateway, or other network device, to a device B outside the firewall, when a device A, which is inside the firewall, requests information from the device B. The device B may pass the digital baton to subsequent electronic devices that may respond to the request using the digital baton to send messages or information through the firewall to the device A. The firewall authenticates and filters the messages based on authentication of the batons contained within the messages.
