Study Notes
Software, Firmware, and Hybrid Modules
- IUT (Implementation Under Test) and EVM (Evaluated Virtual Machine) must operate in identical or nested operational environments during testing.
- If IUT relies on EVM to fulfill FIPS 140-3 requirements, the test report must clearly demonstrate compliance without violating other FIPS requirements.
- Boundaries between IUT and EVM need careful delineation; reliance on external controls must not introduce non-compliance.
Sensitive Security Parameters
- Sensitive security parameters (SSPs) shifted between IUT and EVM must comply with specific ISO/IEC standards concerning secure entry and establishment.
- The movement of SSPs across cryptographic boundaries necessitates strict adherence to security protocols to maintain security integrity.
EVM Testing Requirements
- EVM does not require retesting during IUT validation; however, the IUT must undergo comprehensive testing.
- For bound modules, EVM must be equal to or exceed IUT's security level across all FIPS sections, with exceptions for "Mitigation of Other Attacks".
Historical Status and Submission Requirements
- Historical validation status of EVM is inherited by the IUT if EVM is moved to a historical list; a module can also become historical due to algorithm transitions.
- EVM must maintain an Active status during IUT submission to the CMVP (Cryptographic Module Validation Program).
- IUT cannot embed or bind to a FIPS 140-2 EVM, ensuring all components are FIPS 140-3 compliant.
Algorithm Certificate Testing
- Algorithms in PAA (Primary Application Area) and PAI (Policy Application Interface) environments must be tested for approval from both software/firmware and PAA/PAI perspectives.
- Hybrid modules support only PAA/PAI or can be classified as software/firmware if tested with and without PAA/PAI.
Module Testing Approaches
- Testing for modules can be conducted with options that include:
- Validating both modes (with PAA/PAI and without) on the same operational environment.
- Testing a hybrid module with PAA/PAI across all operational environments supported, ensuring all combinations are validated.
RSA Signature Generation Testing
- The RSASP1 component of RSA must be tested for all modulus lengths where CAVP (Cryptographic Algorithm Validation Program) testing is applicable, particularly for 2048, 3072, and 4096-bit lengths.
ECDSA Signature Generation
- ECDSA signature generation may use pre-hashed messages to streamline the process, following protocols established in FIPS 186-5.
- It emphasizes that no additional hashing should occur during the ECDSA signing to maintain consistency.
Key Derivation Functions (KDF)
- KDFs from various standards (IKEv1, IKEv2, TLS, etc.) must be employed strictly within their designated protocols to ensure proper functionality.
- Each KDF is assigned a specific algorithm/mode/revision combination for identification within the CAVP framework.
TLS 1.3 Key Derivation
- The TLS 1.3 KDF, based on established NIST-approved standards, is validated under specific sections, ensuring that the functions align with contemporary cryptographic requirements.
