FIPS 140-3: The New Standard in Security

Embrace the future with confidence by designing your products to the latest Federal Information Processing Standard 140-3 (FIPS 140-3) standard.

Ensure your products meet the highest levels of security and compliance required by U.S. and Canadian regulations.

With Corsec’s guidance, navigating this new standard can be seamless and straightforward.

Corsec’s Overviews provide details on the FIPS 140-3 standard, FIPS Inside and FIPS Compliant, and common FIPS 140 Myths and Roadblocks

The Standard: FIPS 140-3

The use of FIPS 140-3 validated products is mandated by Section 5131 of the Information Technology Management Reform Act of 1996.
All products sold into U.S. federal agencies are required to complete FIPS 140-3 validation if they use cryptography in security systems that process Sensitive But Unclassified (SBU) information.
Security requirements are outlined in full within the NIST FIPS 140-3 PUB.

The Requirements: FIPS 140-3

FIPS 140-3 Requirements

FIPS 140-3 contains eleven Derived Test Requirements (DTRs) that detail the requirements that must be provided to demonstrate conformance to the standard. Each section also describes the methods that the testing lab will take to test the module.  Note that the eleven sections of FIPS 140-3 have been updated from the previous FIPS 140-2 version of the standard:

Cryptographic Module Specification:

The new standard defines five types of cryptographic modules or boundaries that can achieve validations; hardware module, firmware module, software module, hybrid-software module, and hybrid-firmware module. Hybrid modules, which were originally restricted to Level 1 validations in FIPS 140-2, no longer have a Level limitation.

Cryptographic Module Interfaces:

This section defines the interfaces or commands used by each module type, the new interfaces include; Hardware Module Interfaces (HMI), Software or Firmware Module Interfaces (SFMI), Hybrid-Software Module Interfaces (HSMI), Hybrid-Firmware Module Interfaces (HFMI), and Control Output Interface.

Software/Firmware Security:

This new section introduces Integrity Testing. This section does not apply to Hardware specific embodiments.

Roles, Services, & Authentication:

Roles: 1.) Crypto Officer Role, 2.) User Role, and 3.) Maintenance Role

The new FIPS 140-3 standard only mandates the Crypto Officer Role.

Services: 1.) Show Status, 2.) Perform Self-Tests, 3.) Perform Approved Security Function, 4.) Show Modules Versioning Information, and 4.) Perform Zeroization

Authentication: Level 4 now requires multi factor identity-based authentication.

Operational Environment:

Updates to this section include the elimination of the need for software modules at a Level 2 to be Common Criteria (CC) certified. However, there are many new requirements that coincide with CC that need to be addressed.

Physical Security:

Embodiments: 1.) Single-chip, 2.) Multiple-chip, and 3.) Multiple-chip Standalone

There are additional requirements at Level 2 (definition changes), Level 3 (tamper evidence seals), and Level 4 (EFP).

Non-Invasive Security:

This section outlines documentation and testing requirements for protecting the module from attacks performed in the absence of direct physical contact to components.

Sensitive Security Parameter Management (SSPs):

A new section in FIPS 140-3. SSPs include both Critical Security Parameters (CSPs) and Public Security Parameters (PSPs). This section covers SSP entry and output requirements at each level; as well as information on Random Bit Generation (RBG), CSP encryption, and Zeroisation.


New requirements for Periodic Self-Tests and Conditional Fault-Detection Tests have been added in addition to renaming Power On Self Tests to Pre-Operational Self-Tests.

Life-Cycle Assurance:

This section is dedicated to security requirements on how the module was designed, developed, and operates.

This section also includes requirements for the module’s End of Life. Additionally, the requirements from FIPS 140-2’s section on Finite State Model (FSM) have been absorbed into this section.

Mitigation of Other Attacks:

A section to address any additional attack mitigating functionality that was not directly called out in previous test requirements.

The Levels: FIPS 140-3

Within each of the eleven DTRs, there are four increasing qualitative security levels. At each level, greater amounts of evidence and engineering are required of the product in order to show compliance with the standard. FIPS 140-3 is retaining the 4 levels of validation:

      Level 1

Previous Requirements
Validation of at least one approved algorithm or security function
 Production-grade evaluated components

      Level 2

Previous Requirements
All Level 1 requirements
 Role-based authentication & physical security requirements for tamper evidence

     Level 3

Previous Requirements
 All Level 1 and 2 requirements
 Identity-based authentication & physical security mechanisms for tamper detection & tamper response

     Level 4

Previous Requirements
 All Level 1, 2, and 3 requirements
 Physical security mechanisms to detect and reply to tampering; including environmental attacks

The Process: Done Once, Done Right

Determining the appropriate approach for your FIPS 140-3 validation is essential; depending on your product, the level you pursue, the boundary you draw, and the engineering changes required, your path to certification could alter greatly.
