International Traffic in Arms Regulations (ITAR)

ITAR encryption controls are located in three primary Categories on the US Munitions List (USML). They are:

  • Category XI - Military Electronics
    • Subparagraph (b) - Encryption software designed or modified to:
      • Generate spreading code for spread spectrum or hopping code for frequency agility (does not include fixed code techniques);
      • Use "burst" (time compression) techniques;
      • Use "burst" (time compression) techniques;
      • Suppress compromising emanations of information bearing signals.
  • Category XIII - Auxiliary Military Equipment
    • Subparagraph (b) - Encryption software designed or modified for:
      • Military information security systems (including key management);
      • Tracking, Telemetry and Control (TT&C) including decryption;
      • Generating spreading or hopping codes for military spread spectrum systems or equipment;
      • Military cryptanalytic systems;
      • Military information systems providing certified or certifiable multi-level security or user isolation exceeding class B2 of TCSEC.
  • Category XV - Spacecraft Systems and Associated Equipment
    • Subparagraph (b) - Encryption software designed or modified for
      • Ground control stations for telemetry, tracking and control of spacecraft or satellites.
    • Subparagraph (c) - Global Positioning System (GPS) receiving equipment:
      • Designed for encryption or decryption (i.e. Y-Code) of GPS precise position service (PPS) signals.
