Abstract
An information flow control means for location between a first and second computer network where the first network has a higher security classification than the second network. The information flow control means comprises an information switch having an information input, a first output connected to the first network, a second output connected to the second network, a controller having at least two states, a first state controlling the information switch to connect the input to the first output and a second state controlling the information switch to connect the input to the second output, and an information diode having an input for receiving information from the second network and an output for transferring information received from the second network to the first network through a connection from the information diode output to the first network and which prevents information flowing from the output to the input.
