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

Encryption is paramount to offering integrity and confidentiality to guard our federal prospects’ knowledge. There are various completely different cryptographic algorithms (corresponding to block cipher, symmetric and uneven algorithms) which can be out there that may encrypt and convert knowledge into unreadable ciphertext. The strategy to do that should be safe. Being Federal Data Processing Normal (FIPS) validated ensures that the encryption strategies used have been independently reviewed and examined earlier than being deployed. FIPS permitted algorithms, to incorporate the transition to the brand new FIPS 140-3 necessities, have endured in depth safety evaluation and are regularly examined to make sure that they may present sufficient safety.


The FIPS 140-3 timeline

The FIPS 140-3 customary 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 large number 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 will likely be moved to the Historic Record. Clients should purchase off the Historic Record and use the FIPS 140-2 modules for present purposes solely. You’ll be able to 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 World Certification and Frequent Safety Modules Workforce has carried out an modern 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 be aware that the crypto module is already FIPS-validated, so the Cisco product using it will possibly declare compliance to FIPS 140.

What’s a cryptographic module?

A cryptographic module is a software program or {hardware} gadget/part that performs cryptographic operations securely implementing the cryptographic logic and processes that assist the safety features 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, embrace:

  • 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 permitted safety features corresponding to cryptographic algorithms, cryptographic key administration methods, and authentication methods.

Understanding FIPS 140-2

The FIPS 140-2 customary stipulates the safety necessities wanted by a cryptographic module. In a nut shell, FIPS 140-2 is a pc safety cryptography customary utilized by the US Federal Authorities when cryptographic-based safety programs and telecommunication programs are used to offer safety of delicate however unclassified knowledge as outlined in Part 5131 of the Data Expertise Administration Reform Act of 1996, Public Legislation 104-106. Cisco is required to satisfy this customary 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 take care of the confidentiality and integrity of the data that’s being protected. The FIPS 140-2 customary bears 4 ranges of accelerating safety:

  1. Safety Stage 1: Gives fundamental safety necessities for a cryptographic module. Stage 1 will need to have not less than one permitted algorithm or permitted 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 choose 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 selected function.  The system should even be evaluated on the Frequent 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 having access to the important safety parameters (CSPs) held inside 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 reinforces the safety supplied by degree 2 role-based authentication mechanisms. The system should even be evaluated on the Frequent Standards analysis assurance degree EAL3 or larger.
  4. Safety Stage 4: This degree offers 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 circumstances or variations of regular working ranges of voltage and temperature. Intentional junkets past the traditional working ranges could also be utilized by an attacker to avoid a cryptographic modules protection. The system should even be evaluated on the Frequent 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, fairly than encompassing the module necessities immediately, FIPS 140-3 references ISO/IEC 19790:2012. NIST additionally notes that the testing for these ISO/IEC 19790:2012 necessities will likely 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 nevertheless, several types of modules had been created (e.g., software program and firmware modules, in addition to hybrid modules). The brand new FIPS 140-3 customary will embrace {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 customary.
  • FIPS 140-2 required {that a} module assist the next roles: person function, crypto officer function, and a upkeep function (this function was non-obligatory). The FIPS 140-3 customary 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 non-obligatory in FIPS 140-3.
  • Inside ISO 19790 the FIPS 140-3 customary is just like the FIPS 140-2 customary 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 could be that FIPS 140-3 degree 4 authentication requires multi-factor id.
