Patent ID: 7388958

Claim:
A confined communication system for internally communicating a plurality of data signals having different levels of security, said communication system comprising: a data source positioned within a high-trust confined space including; a low security encryptor for converting low security input signals to low security internal data signals having low security internal encryption; a high security encryptor for converting high security input signals to high security internal data signals having high security internal encryption; and a data destination positioned within said high-trust confined space including; a low security decryptor for converting said low security internal data signals to low security output signals; a high security decryptor for converting said high security internal data signals to high security output signals; and a switching unit positioned within said high-trust confined space for receiving said low and high security internal data signals and directing said low security internal data signals or said high security internal data signals or said low and high security internal data signals to said data destination, wherein said low and high security internal data signals are continuously retained in said high-trust confined space and said switching unit and said data destination use said low security internal encryption and high security internal encryption to segregate and compartmentalize said low security internal data signals from said high security internal data signals.
