The Federal Information Processing Standard Publication 140-2, (FIPS PUB 140-2), [1] [2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules .
As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. [1] FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became effective on September 22, 2019. [2] FIPS 140-3 testing began on September 22, 2020, and a small number of validation certificates have been issued.
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).
The Suite B algorithms have been replaced by Commercial National Security Algorithm (CNSA) Suite algorithms: [7] Advanced Encryption Standard (AES), per FIPS 197, using 256 bit keys to protect up to TOP SECRET; Elliptic Curve Diffie-Hellman (ECDH) Key Exchange, per FIPS SP 800-56A, using Curve P-384 to protect up to TOP SECRET.
A Type 1 Product refers to an NSA endorsed classified or controlled cryptographic item for classified or sensitive U.S. government information, including cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed.
Current list of FIPS 140 validated cryptographic modules with validated AES implementations (hosted by NIST) – Most of these involve a commercial implementation of AES algorithms. Look for "FIPS-approved algorithms" entry in the "Level / Description" column followed by "AES" and then a specific certificate number.
FIPS 140-3 testing began on September 22, 2020, and a small number of validation certificates have been issued. FIPS 140-2 testing was available until September 21, 2021, creating an overlapping transition period of one year. FIPS 140-2 test reports that remain in the CMVP queue will still be granted validations after that date, but all FIPS ...
FIPS PUB 140-2 Security Requirements for Cryptographic Modules 2001, defines four increasing security levels; FIPS PUB 171 Key Management Using ANSI X9.17 (ANSI X9.17-1985) 1992, based on DES; FIPS PUB 180-2 Secure Hash Standard (SHS) 2002 defines the SHA family; FIPS PUB 181 Automated Password Generator (APG) 1993
