# Intel(R) Cryptography Primitives Library FIPS

## What is FIPS 140?

FIPS (Federal Information Processing Standard) 140 series are U.S. government
computer security standards that specify requirements for cryptography modules.
The latest version is FIPS 140-3 (ISO standard 19790).

### Who needs FIPS 140?

The National Institute of Standards and Technology (NIST) issues the 140
Publication Series to coordinate the requirements and standards for
cryptographic modules which include HW, SW, and/or FW components for use by
**departments and agencies of the U.S. government**.
In U.S., government agencies desiring to deploy cryptographic modules should
confirm that the module they are using has a valid FIPS 140 certificate.
The Government of Canada also recommends the use of FIPS 140 validated
cryptographic modules in unclassified applications of its departments.
In addition, **in recent years FIPS 140 has become a more and more popular requirement in financial and health care sectors as well**.

## FIPS-Certified vs FIPS-Compliant

FIPS 140-3 defines 4 security levels (from level 1 - the easiest to level 4 - the most stringent).
In general, software may be certified at up to level 2.

Intel® Cryptography Primitives Library
provides building blocks of FIPS-mode API (such as self-tests, FIPS-approved
functionality status query) which can help the end users to fulfill FIPS level 1 requirements.
Please, refer to [Covered Algorithms](#covered-algorithms) section for the full
list of FIPS-Approved API which are covered with the selftests.

> NOTE: Intel® Cryptography Primitives Library is not **FIPS-Certified** on its own but **FIPS-Compliant**:
that means Intel® Cryptography Primitives Library releases will have Cryptographic Algorithm
Validation Program (CAVP) testing and certification done but don't have full
Cryptographic Module Validation Program certificate as the context of the usage
of Intel® Cryptography Primitives Library's high-performant primitives depends on a more high-level application.

For the results of CAVP testing please refer to [Latest Certification](./README.md#latest-certification) chapter.

Intel® Cryptography Primitives Library may be built in FIPS-mode with IPPCP_FIPS_MODE=on
configuration for ippcp and MBX_FIPS_MODE=on for crypto_MB (see details in [Build section](#build)).

Application, which uses Intel® Cryptography Primitives Library may be **FIPS-Certified** by
matching FIPS 140 requirement and obtaining NIST certificate or also be **FIPS-Compliant** for their own customers.

Please, refer to [Level 1 Specific Requirements](#level-1-specific-requirements)
for the detailed description of what is done on Intel® Cryptography Primitives Library-side
and what should be done by a more high-level application.

### Level 1 Specific Requirements

| # | Requirement | Note |
|---|-------------|------|
| 1 |Provide service to output module's name / identifier and version to User | Intel® Cryptography Primitives Library provides such functionality via ippcpGetLibVersion() API for IPPCP and mbx_getversion() API for crypto_MB |
| 2 |For every service, output to the user whether it is a FIPS-approved service or not | Intel® Cryptography Primitives Library provides such functionality via [ippcp_is_fips_approved_func](#api-for-an-indicator-if-a-function-is-fips-approved) for ippcp and [mbx_is_fips_approved_func](#crypto-multi-buffer-library-api-for-an-indicator-if-a-function-is-fips-approved) for crypto_MB |
| 3 |Zeroize unprotected keys using manual/procedural destruction method | **User's application effort required** |
| 4 |Run integrity selftest at power on for SW component | **User's application effort required** |
| 5 | Run known-answer or comparison or fault-detection selftest for individual crypto algorithms before first use | Intel® Cryptography Primitives Library provides [fips_selftest_ippcp<algorithm name> API](#covered-algorithms) to run selftests. User's application should call them before the first use of algorithm (see [Example](#example-of-api-usage)) |
| 6 | Run pairwise consistency selftest for newly generated RSA/ECC keypair | Intel® Cryptography Primitives Library provides [fips_selftest_ippcp<algorithm name> API](#covered-algorithms) to run selftests |
| 7 | Module to guarantee uniqueness of GCM key + IV | **User's application effort required** |
| 8 | Module to guarantee XTS key1 != key2 | Intel® Cryptography Primitives Library-side check |
| 9 | (non-production) Extract raw noise source output samples of RBG for quality analysis | DBRNG is currently out of the cryptography boundary |
| 10| (non-production) Run crypto algorithm testing with NIST-generated vectors | Done offline by Intel® Cryptography Primitives Library for the [covered algorithms](#covered-algorithms) |

For the implementation details about the steps in [Level 1 Specific Requirements](#level-1-specific-requirements)
specified as **User's application effort required** please refer to the
[Implementation Guidance for FIPS 140-3 and the Cryptographic Module Validation Program](https://csrc.nist.gov/csrc/media/Projects/cryptographic-module-validation-program/documents/fips%20140-3/FIPS%20140-3%20IG.pdf) by the National Institute of Standards and Technology.

## Cryptographic boundary

### Intel® Cryptography Primitives Library Structure Diagram

![Intel® Cryptography Primitives Library Architecture](./data/images/README_FIPS-pictures-0-ippcp_architecture.png)

1. Intel® Cryptography Primitives Library uses special structures (Spec and States)
to store context information and provides service functions to work with context (e.g. Initialization).

> Note: Application responsible for the life-cycle of context. All memory allocations
and sanitizing happens on application side (including #3 in [Level 1 Specific Requirements](#level-1-specific-requirements)).

2. Cryptographic Algorithms API (both FIPS-Compliant and not FIPS Compliant).
3. FIPS Self-tests API and service to query if algorithm is FIPS-Compliant
(API for #2, #5, #6 in [Level 1 Specific Requirements](#level-1-specific-requirements)).
4. Version information (API for #1 in [Level 1 Specific Requirements](#level-1-specific-requirements)), Dispatcher control.
5. Intel® Cryptography Primitives Library chooses the optimal code path depending on
hardware features and application settings (via Dispatcher control API).
6. The algorithms may have multiple code branches for different hardware
architecture and different compilation flags may be used to achieve better performance.

Refer to [Covered Algorithms](#covered-algorithms) section to check which
algorithms are within the cryptographic boundary.

> Note: For #10 in [Level 1 Specific Requirements](#level-1-specific-requirements)
Intel® Cryptography Primitives Library tests all code-paths and algorithms modes as
the implementation may vary depending on the target hardware.

## Intel® Cryptography Primitives Library Usage in the FIPS-mode

### Build

CMake flag -DIPPCP_FIPS_MODE:BOOL=on should be used to build ippcp library and
-DMBX_FIPS_MODE:BOOL=on for crypto_MB in FIPS-mode. These modes enable extra API for
self-tests and FIPS-support query (see [covered algorithms](#covered-algorithms) for the details).
Selftests can be build in two modes - with internal memory allocation or without it.

Configuration example for ippcp with Intel® oneAPI DPC++/C++ Compiler:

`CC=icx CXX=icpx cmake CMakeLists.txt -B_build -DARCH=intel64 -DIPPCP_FIPS_MODE:BOOL=on [-DIPPCP_SELFTEST_USE_MALLOC:BOOL=on]`

> Note: selftests with internal memory allocation uses malloc, which introduces
a c runtime dependency.
To avoid the dependency, use IPPCP_SELFTEST_USE_MALLOC:BOOL=off or do not specify
it as this as the default. In this case, all self-tests will require external memory allocation.

Configuration example for crypto_MB with GCC:

`CC=gcc CXX=g++ cmake CMakeLists.txt -B_build -DARCH=intel64 -DMBX_FIPS_MODE:BOOL=on`

### Example of API Usage

#### Intel® Cryptography Primitives Library Example

```cpp

//------ FIPS-required part

// 1. check that the function is FIPS-approved:
if(!ippcp_is_fips_approved_func(AESEncryptCBC)) {
    return -1; // cannot use this function in FIPS mode.
}

// 2. Run the Selftest
fips_test_status selftest_status = IPPCP_ALGO_SELFTEST_OK;

// Query buffer size for the test and allocate it (it can be done on Intel® Cryptography Primitives Library side with IPPCP_SELFTEST_USE_MALLOC=on)
int BuffSize = 0;
selftest_status += fips_selftest_ippsAESEncryptDecrypt_get_size(&BuffSize);
std::vector<Ipp8u> pBuff(BuffSize);

// Run the test
selftest_status += fips_selftest_ippsAESEncryptCBC(pBuff.data());

// Check selftest status
if (IPPCP_ALGO_SELFTEST_OK != selftest_status) {
    return -1; // selftest is not successful -> cannot use this function in FIPS mode.
}

//------ FIPS-required part ends (only needed before the first use of algorithm)

//------ Common Intel® Cryptography Primitives Library usage
// ...
IppStatus status = ippsAESEncryptCBC(plain, cipher, block_size, pAES, cipherV);
// ...

```

#### Crypto Multi-buffer Library Example

```cpp

//------ FIPS-required part

// 1. check that the function is FIPS-approved:
if(!mbx_is_fips_approved_func(nistp256_ecdh_mb8)) {
    return -1; // cannot use this function in FIPS mode.
}

// 2. Run the Selftest
if (fips_selftest_mbx_nistp256_ecdh_mb8() != MBX_ALGO_SELFTEST_OK) {
    return -1; // selftest is not successful -> cannot use this function in FIPS mode.
}

//------ FIPS-required part ends (only needed before the first use of algorithm)

//------ Common Crypto Multi-buffer Library usage
// ...
mbx_nistp256_ecdh_mb8(sharedAB, prvA, pubBx, pubBy, pubBz_curr, 0);
mbx_nistp256_ecdh_mb8(sharedBA, prvB, pubAx, pubAy, pubAz_curr, 0);

// ...
