Abstract
An improved multi-channel data encryption system is described. The multi-channel data encryption device of the present invention includes a plurality of data of encryption devices in a single unit wherein each of the data encryption devices are adapted for independent operation. The plurality of data encryption devices are coupled with a data bus wherein encryption key information may be programmed in the plurality of data encryption devices through the data bus. The present invention provides a means for assigning the data encryption devices to predefined groups wherein encryption key information may be simultaneously programmed into encryption devices within the assigned groups, thus eliminating the need for individually programming the data encryption devices.
