Abstract
A personal computer or 'host computer' and a Mass storage device are arranged on an SCSI bus. A 'decryption controller', in a separate enclosure outside of the host computer, is also arranged on the SCSI bus. This controller is addressable by the host computer as if it were the mass storage device. Upon receipt of an information request, the decryption controller initiates a request to the mass storage device for the desired information, retrieves this information, decrypts it (if it is encrypted) and then passes it to the host computer. The decryption controller is thus 'transparent' to the host computer.
