Such techniques are extremely valuable against the hacker problem and unauthorized use of resources. It is the stated policy of the NSA not to restrict the export of authentication products, only encryption products. If you want to export an authentication-only product, approval may merely be a matter of showing that your product cannot easily be used for encryption. Furthermore, the bureaucratic procedures are much simpler for authentication products than for encryption products. An authentication product needs State Department approval only once for a CJ; an encryption product may require approval for every product revision or even every sale. Without a CJ, you must request export approval every time you wish to export the product. The State Department does not approve the export of products with strong encryption, even those using DES. Isolated exceptions include export to U.S. subsidiaries for the purposes of communicating to the U.S., exports for some banking applications, and export to appropriate U.S. military users. The Software Publishers Association (SPA) has been negotiating with the government to ease export license restrictions. A 1992 agreement between them and the State Department eased the export license rules for two algorithms, RC2 and RC4, as long as the key size is 40 bits or less. Refer to Section 7.1 for more information. In 1993, Rep. Maria Cantwell (D-WA) introduced a bill at the behest of the software industry to relax export controls on encryption software. Sen. Patty Murray (D-WA) introduced a companion bill in the Senate. The Cantwell Bill was appended to the general export control legislation going through Congress, but was deleted by the House Intelligence Committee after a massive lobbying effort by the NSA. Whatever the NSA did, it was impressive; the committee voted unanimously to delete the wording. I can’t remember the last time a b...
