SECURE ONE-WAY INTERFACE FOR A NETWORK DEVICE

摘要

A one-way interface for a network device which secures status registers therein from unauthorized changes. The interface includes a first server, a one-way data link and a second server. The first server is coupled to the status registers to read information stored therein. The first server reads the information from the status registers and transmits the information on an output. The one-way data link has an input coupled to the output of the first server and an output. The second server has an input coupled to the output of the one-way data link and an output coupled to a network. The second server receives the information from the first server via the one-way data link. The second server transmits the information on the output to a predetermined network destination and/or provides a user interface for providing access to the information via the network.
