The Federal Information Processing Standard Publication 140-3 is an announced update to the U.S. governmentcomputer securitystandard used to accredit cryptographic modules. The title of the standard is Security Requirements for Cryptographic Modules and FIPS 140-2 remains the currently approved version. Efforts to update FIPS 140-2 date back to the early 2000s. The FIPS 140-3 was scheduled for signature by the Secretary of Commerce in August 2013, however that never happened and the draft was subsequently abandoned. In 2014, NIST released a substantially different draft of FIPS 140-3, this version effectively directing the use of an International Organization for Standardization/International Electrotechnical Commission standard, 19790:2012, as the replacement for FIPS 140-2. The 2014 draft of FIPS 140-3 was also abandoned. On August 12, 2015, NIST formally released a statement on the Federal Register asking for comments on the potential use of portions of ISO/IEC 19790:2014 in the update of FIPS 140-2. The reference to a 2014-version of ISO/IEC 19790 was an inadvertent error in the Federal Registry posting, as 2012 is the most recent version. The update process for FIPS 140 has been hamstrung by deep technical issues in topics such as hardware security and apparent disagreement in the US government over the path forward. The now abandoned 2013 draft of FIPS 140-3 had required mitigation of non-invasive attacks when validating at higher security levels, introduced the concept of public security parameter, allowed the deference of certain self-tests until specific conditions are met, and strengthened the requirements on user authentication and integrity testing. It remains unclear whether these issues will be addressed in the ultimately approved release of FIPS 140-3.
Purpose
The National Institute of Standards and Technology issued the FIPS 140 Publication Series to coordinate the requirements and standards for cryptography modules that include both hardware and software components. Federal agencies and departments can validate that the module in use is covered by an existing FIPS 140-2 certificate that specifies the exact module name, hardware, software, firmware, and/or applet version numbers. The cryptographic modules are produced by the private sector or open source communities for use by the U.S. government and other regulated industries that collect, store, transfer, share and disseminate sensitive but unclassified information. A commercial cryptographic module is also commonly referred to as a hardware security module.
FIPS 140-2 establishes the Cryptographic Module Validation Program as a joint effort by the NIST and the Communications Security Establishment for the Canadian government. Security programs overseen by NIST and CSEC focus on working with government and industry to establish more secure systems and networks by developing, managing and promoting security assessment tools, techniques, services, and supporting programs for testing, evaluation and validation; and addresses such areas as: development and maintenance of security metrics, security evaluation criteria and evaluation methodologies, tests and test methods; security-specific criteria for laboratory accreditation; guidance on the use of evaluated and tested products; research to address assurance methods and system-wide security and assessment methodologies; security protocol validation activities; and appropriate coordination with assessment-related activities of voluntary industry standards bodies and other assessment regimes.
Approval and issurance
On March 22, 2019, the United States Secretary of CommerceWilbur Ross approved FIPS 140-3, Security Requirements for Cryptographic Modules to succeed FIPS 140-2. According to the announcement, FIPS 140-3 will become effective on September 22, 2019. Validated through the Cryptographic Module Validation Program, FIPS 140-3 testing will begin September 22, 2020. After FIPS 140-3 testing begins, FIPS 140-2 testing will continue for at least a year, making the two standards to coexist for some time.
