  • System and method for providing a secure book device using cryptographically secure communications across secure networks
    Patent number: 9172685
    Abstract: A system for integrating access to separate and physically partitioned networks from a single client device is described. The system is interposed between the client device and the networks to allow communication between the client device and the networks, such that data remains partitioned between networks. The system includes a scrambler configured to mix portions of data of variable bit lengths. Typically, the scrambler receives the portions of data from each of the plurality of networks, intermixes the portions of data from the networks, then selects different paths for transporting the intermixed portions of data to the client device. Each of the different paths for transporting the intermixed portions of data are physically and/or logically partitioned from each other. Only when the data arrives on the client device is it able to be reassembled, and then only in particular partitioned locations on the client device corresponding to the particular network from which the data originated.
