Abstract
The present invention provides a method and system for secure access to computer equipment. An embodiment includes a secure access controller connected to a link between a transceiver (such as a modem) and the computer equipment. Public and private keys are used by the secure access controller and a remote user. The keys are provided to the secure access controller by an authentication server. Once the transceiver establishes a communication link with the user, the access controller uses these keys to authenticate packets issued by the user to the computer equipment. If the packet is authenticated, the access controller passes the packet to the computer equipment. Otherwise, the packet is discarded. Another embodiment includes a secure access controller having a plurality of ports for connection to a plurality of different pieces of computer equipment. The secure access controller thus intermediates communications between the modem and the plurality of different pieces of computer equipment.
