Abstract
An intermediate device (such as a firewall) is disposed between first and second devices (such as a client and a server device, respectively). Communications between the first and second devices are intercepted in both directions by the intermediate device, which spoofs the receiving device by modifying messages sent by the transmitting device. The modified message uses a key held by the intermediate device instead of a key belonging to the sending device.
