NSA product types
Product types refers to nomenclature that has been used by the U.S. National Security Agency (NSA) to rank cryptographic products or algorithms by level of certification. The terminology is defined in the National Information Assurance Glossary (CNSSI No. 4009) which defines Type 1, Type 2, products and Type 3, and Type 4 algorithms.〔(National Information Assurance Glossary ) (CNSSI No. 4009), 2003〕
==Type 1 product==
A Type 1 product is a device or system certified by NSA for use in cryptographically securing classified U.S. Government information. A Type 1 product is defined as:
: ''Classified or controlled cryptographic item endorsed by the NSA for securing classified and sensitive U.S. Government information, when appropriately keyed. The term refers only to products, and not to information, key, services, or controls. Type 1 products contain approved NSA algorithms. They are available to U.S. Government users, their contractors, and federally sponsored non-U.S. Government activities subject to export restrictions in accordance with International Traffic in Arms Regulations.''
Type 1 certification is a rigorous process that includes testing and formal analysis of (among other things) cryptographic security, functional security, tamper resistance, emissions security (EMSEC/TEMPEST), and security of the product manufacturing and distribution process.
