Abstract
A data loader device is used to convey digital data in a secure manner to another device. The data loader may be fixed (referred to as a Class_A loader) or portable (referred to as a Class_B loader). The data loader encrypts the digital data using a location-identity that permits the digital data to be transferred only if the data loader is disposed at an appropriate location. The fixed data loader remains in a stationary location, and a device to be loaded is brought to the data loader for loading. The portable data loader can be loaded by the fixed data loader, and then transported to another location to load a recipient device. The digital data that is conveyed is unrestricted in nature, and can include keys, navigational information, watermarking parameters, or any other digital content requiring secure delivery. In an embodiment, the data loader device includes a “no-move” system that precludes compromise of data contained therein if the data loader device is moved. Upon detection of movement above a predefined threshold level, the “no-move” system produces an alarm condition that inhibits operation of the device.
