Chi Tong Kuok, from Macau, China, was convicted on four counts related to attempting to have the equipment sent to Macau and Hong Kong. The equipment included an encryption device for Internet communications for the U.S. military made under contract by the National Security Agency, prosecutors said. Additionally, he tried to buy a GPS device used by the U.S. and NATO militaries and a device used by American and NATO forces to load encryption software into their communications devices, they said. U.S. law bans the export of such devices without permission from the State Department.
