Type 1 encryption
In cryptography, a Type 1 product is a device or system certified by the National Security Agency (NSA) for use in cryptographically securing classified U.S Government information. Type 1 certification is a rigorous process that includes testing and formal analysis of (among other things) cryptographic security, functional security, tamper resistance (QUADRANT), emissions security (EMSEC/TEMPEST), and security of the product manufacturing and distribution process. For a historically-oriented list of NSA encryption products (most of them Type 1), see NSA encryption systems. For algorithms that NSA has participated in the development of, see NSA encryption algorithms.
