ABSTRACT:
A data encryption device with a plurality of data encryption boards for encrypting data is provided. In a preferred embodiment, the data encryption device has a monitor processor connected to a parallel bus. Each data encryption board has a parallel port for connection to the parallel bus and a serial port for connection to a host computer. Each data encryption board operates independently of the other data encryption boards. A plurality of data encryption boards may be connected to the bus. In operation, a host computer sends data to a data encryption board. The data encryption board encrypts the data and sends the encrypted data to the host processor. The monitor processor and the data encryption boards are preferably in the same housing unit with a tamper detection mechanism.
