The present concept of keying Communications Security (COMSEC) and Communication/Navigation (COM/NAV) systems employed on aircraft may not be operationally suitable for keying multiple devices in future aircraft. The existing method for initiating the keying process for COMSEC equipment requires the insertion of a COMSEC code into COMSEC systems and a non-COMSEC Transmission Security (TRANSEC) code for anti-jam protection into COM/NAV systems. This is accomplished using a taper reader, a key fill device, or as in some communications systems, a system-unique fill device. As more advanced avionic systems come into the inventory, there will be more needs for COMSEC/TRANSEC keying. Flight line control and distribution of large numbers of key codes and fill devices involves an increased workload and turnaround time. Inserting keys into numerous COMSEC and COM/NAV devices requires the removal of multiple aircraft panels and sometimes aircraft equipment. Incorrect loading of key is not recognized until the aircraft is powered up and external system check completed.
