Abstract
In overview, an integrated circuit in accordance with the disclosure comprises first and second network interface processors which are separate processors and which are connected by a first unidirectional interconnect. The first unidirectional interconnect allows data transfer from the first network interface processor to the second network interface processor, while preventing data transfer in the reverse direction. The first network interface processor is for communication with a first network which may be a secure network and the second network interface processor is for communication with second network which may be a public network, for example an insecure public network. In this way, the processing of data received from each of the first and second networks is performed by separate processors and data can only be sent from the first network to the second network, thereby protecting the first network from the second network.
