Abstract
The security level of a communications terminal can be changed during operation. A key loading device can reconstitute a key encryption key from plural split portions. The split portions can be loaded into the key loading device via various interfaces. The reconstituted key encryption key can be used to unwrap wrapped keys stored in the key loading device.
