NSA product types
device or system certified by the National Security Agency for use in cryptographically securing classified U.S. Government information
The U.S. National Security Agency (NSA) used to rank cryptographic products or algorithms by a certification called product types. Product types were defined in the National Information Assurance Glossary (CNSSI No. 4009, 2010) which used to define Type 1, 2, 3, and 4 products. The definitions of numeric type products have been removed from the government lexicon and are no longer used in government procurement efforts.
Type 1 product
A Type 1 product was a device or system certified by NSA for use in cryptographically securing classified U.S. Government information. A Type 1 product was defined as:
Cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Developed using established NSA business processes and containing NSA approved algorithms. Used to protect systems requiring the most stringent protection mechanisms.
They were 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 was a rigorous process that included 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.
This brief starts where responsible research should: with the source description of “NSA product types” as device or system certified by the National Security Agency for use in cryptographically securing classified U.S. Government information. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as device or system certified by the National Security Agency for use in cryptographically securing classified U.S. Government information. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Apr 15, 2025. The linked authority identifier is Q7860676. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
