Abstract:
1. A computing apparatus comprising: a digital data storage device; a bus-to-bus bridge configured to receive digital data from a host processor and to forward the digital data to the digital data storage device in an encrypted form, wherein the bus-to-bus bridge is configured to encrypt the digital data and forward the digital data to the digital storage device without intervention of the host processor, and wherein the bus-to-bus bridge is configured to selectively enable and disable encryption depending on the target device that is to receive the data that is transmitted via the bus-to-bus bridge; a non-volatile memory location in or connected to the logic circuit bus-to-bus bridge which stores an identification code; and a key accessed by the logic circuit bus-to-bus bridge to define at least in part an encryption process, wherein the key is derived at least in part from the identification code.
