(International Traffic in Arms Regulations) U.S. State Department regulations that govern the export of restricted technology to foreign states other than Canada. The ITAR included restrictions on commercial encryption products until the end of 1996, when they were passed to the Export Administration Regulations (EAR) of the Department of Commerce. See Wassenaar Arrangement and EAR.
The United States government controls the export and import of defense-related materials and technology through this regulation. Many IT security-related technologies—particularly encryption technologies—fall under ITAR and are therefore restricted from export.
