interoperable encryption of airborne still and motion imagery communications the DoD Components shall only use devices systems and technologies in accordance with the following methods a U KGV135A with common data link CDL waveforms for Unclassified Secret or Top Secret communications implemented in accordance with Information Assurance Advisory 0012007 Reference d 1 U The AES module shall resynchronize automatically if synchronization is lost For AES implementation in conjunction with CDL equipment use the AES module shall be self synchronizing using multiplexer frame synch bits to align the data blocks in accordance with the Performance Specification for the Standard CDL Waveform Reference h 2 U Figure 2 of Reference f defines the bit I byte numbering for the 128bit block of the AES algorithm The first bit of serial data shall be stored in the bit127 location as shown in Figure 2 of Reference f c U AES for Unclassified nonCDL based systems shall also implement AES as defined in this enclosure d U Systems using the KGV135A or AES shall use NSA CSS generated keys e U As new encryption methods for the transmission and reception of airborne still and motion imagery are approved for implementation by NSA CSS commercial or government they will be considered for inclusion as a standard interoperable encryption method in this Instruction The DoD will seek to leverage commercial encryption where operationally feasible 2 U UNCLASSIFIED COMMUNICATIONS DoD Components shall ensure that unclassified airborne still and motion imagery communications and unmanned
