Cisco is Transitioning from FIPS 140-2 to FIPS 140-3

Encryption is paramount to offering integrity and confidentiality to guard our federal clients’ information. There are various totally different cryptographic algorithms (akin to block cipher, symmetric and uneven algorithms) which might be accessible that may encrypt and convert information into unreadable ciphertext. The tactic to do that should be safe. Being Federal Data Processing Commonplace (FIPS) validated ensures that the encryption strategies used have been independently reviewed and examined earlier than being deployed. FIPS authorized algorithms, to incorporate the transition to the brand new FIPS 140-3 necessities, have endured intensive safety evaluation and are regularly examined to make sure that they are going to present ample safety.


The FIPS 140-3 timeline

The FIPS 140-3 commonplace supersedes FIPS 140-2, and it turned efficient September 22, 2019. Validation efforts underneath FIPS 140-3 started in September 2020.  FIPS 140-3 covers a mess of vulnerabilities and threats defining safety necessities for Cisco from preliminary design to operational deployment. On April 1, 2021, The Cryptographic Module Validation Program (CMVP) now not excepted FIPS 140-2 submissions for brand spanking new validation certificates and validation ended for FIPS 140-2 on September 22, 2021. These FIPS 140-2 modules can stay lively till September 21, 2026, then shall be moved to the Historic Listing. Clients should purchase off the Historic Listing and use the FIPS 140-2 modules for current functions solely. You may can discover extra right here at NIST.

Cisco has a number of FIPS 140-3 validations in course of and can proceed to maneuver the portfolio of FIPS 140-2 validations to FIPS 140-3 over the subsequent a number of years.

Cisco’s International Certification and Widespread Safety Modules Group has carried out an progressive method to expedite FIPS certifications. They’ve developed a crypto module that’s already FIPS-validated and could be embedded in Cisco merchandise. You will need to observe that the crypto module is already FIPS-validated, so the Cisco product using it might declare compliance to FIPS 140.

What’s a cryptographic module?

A cryptographic module is a software program or {hardware} system/element that performs cryptographic operations securely implementing the cryptographic logic and processes that assist the safety capabilities in a pc or digital system. The Nationwide Institute of Requirements and Expertise (NIST) notes that the areas coated, associated to the safe design and implementation of a cryptographic module, embody:

  • Specification
  • Ports and Interfaces
  • Roles
  • Companies
  • Authentication
  • Finite State Module
  • Bodily Safety
  • Operational Atmosphere
  • Cryptographic Key Administration
  • Electromagnetic Interference/Electromagnetic Compatibility
  • Self-Checks
  • Design Assurance and,
  • Mitigation of different Assaults.

Cryptographic Modules that conform to FIPS make use of authorized safety capabilities akin to cryptographic algorithms, cryptographic key administration strategies, and authentication strategies.

Understanding FIPS 140-2

The FIPS 140-2 commonplace stipulates the safety necessities wanted by a cryptographic module. In a nut shell, FIPS 140-2 is a pc safety cryptography commonplace utilized by america Federal Authorities when cryptographic-based safety programs and telecommunication programs are used to offer safety of delicate however unclassified information as outlined in Part 5131 of the Data Expertise Administration Reform Act of 1996, Public Regulation 104-106. Cisco is required to satisfy this commonplace to have the ability to promote its merchandise into federal businesses such because the Intelligence Group and Division of Protection.

Defending cryptographic modules is important to keep up the confidentiality and integrity of the knowledge that’s being protected. The FIPS 140-2 commonplace bears 4 ranges of accelerating safety:

  1. Safety Stage 1: Supplies fundamental safety necessities for a cryptographic module. Stage 1 will need to have at the least one authorized algorithm or authorized safety perform. No particular bodily safety mechanisms are required.
  2. Safety Stage 2: Enhances the bodily safety mechanisms of a Safety Stage 1 cryptographic module by including the requirement of tamper-evidence (coatings or seals or decide resistant. Locks on detachable covers or doorways of the module). This degree additionally requires role-based authentication through which a cryptographic module authenticator permits the authorization of an operator to imagine a particular function.  The system should even be evaluated on the Widespread Standards analysis assurance degree EAL2 or larger.
  3. Safety Stage 3: Along with the tamper-evident bodily safety mechanisms required at Stage 2, Safety Stage 3 necessities forestall an intruder from getting access to the important safety parameters (CSPs) held throughout the cryptographic module. Bodily safety mechanisms at this degree can detect and reply to bodily entry, use, or modification. This degree additionally requires identity-based authentication mechanisms which boosts the safety supplied by degree 2 role-based authentication mechanisms. The system should even be evaluated on the Widespread Standards analysis assurance degree EAL3 or larger.
  4. Safety Stage 4: This degree gives the best degree of safety outlined in FIPS 140-2. The bodily safety mechanisms should present an entire envelope of safety across the cryptographic module with the intent of detecting and responding to all unauthorized makes an attempt at bodily entry. This degree additionally protects the cryptographic module in opposition to environmental situations or variations of regular working ranges of voltage and temperature. Intentional junkets past the conventional working ranges could also be utilized by an attacker to avoid a cryptographic modules protection. The system should even be evaluated on the Widespread Standards analysis assurance degree EAL4 or larger.

FIPS 140-2 and FIPS 140-3 differentiation

NIST notes that the brand new FIPS 140-3 introduces some vital adjustments from FIPS 140-2. For instance, slightly than encompassing the module necessities instantly, FIPS 140-3 references ISO/IEC 19790:2012. NIST additionally notes that the testing for these ISO/IEC 19790:2012 necessities shall be outlined with ISO/IEC 24759:2017.

NIST goes on to say that there are few main technical requirement adjustments from FIPS 140-2 to FIPS 140-3, however the utilization of those ISO paperwork requires procedural adjustments within the administration and execution of the validation program and course of. FIPS 140-2 to FIPS 140-3 differentiation is as follows:

  • When FIPS 140-2 was first written, encryption modules had been all {hardware} modules. Over time nonetheless, various kinds of modules had been created (e.g., software program and firmware modules, in addition to hybrid modules). The brand new FIPS 140-3 commonplace will embody {hardware} modules, software program modules, hybrid-software modules, and hybrid firmware modules.
  • FIPS 140-2 additionally restricted hybrid modules to solely a FIPS 140-2 Stage 1 validation certification. FIPS 140-3 doesn’t have this restriction, now a hybrid module could be validated at any degree within the new commonplace.
  • FIPS 140-2 required {that a} module assist the next roles: person function, crypto officer function, and a upkeep function (this function was optionally available). The FIPS 140-3 commonplace nonetheless has these three roles, however the crypto officer function is the one one that’s required. Each the person function and the upkeep function are optionally available in FIPS 140-3.
  • Inside ISO 19790 the FIPS 140-3 commonplace is just like the FIPS 140-2 commonplace the place Stage 1 has no authentication necessities, degree 2 has minimal role-based authentication, and degree 3 has identity-based authentication. The distinction now’s that FIPS 140-3 degree 4 authentication requires multi-factor identification.
