Monolithic Build (Native Backend)

This directory contains a minimal example for building mldsa-native as a single compilation unit with native assembly backends, using the auto-generated mldsa_native.c and mldsa_native_asm.S files.

Use Case

Use this approach when:

• You need only one ML-DSA parameter set (44, 65, or 87)
• You want simple build integration with optimal performance

Components

1. Source tree mldsa_native/*, including top-level compilation unit mldsa_native.c (gathering all C sources), mldsa_native_asm.S (gathering all assembly sources), and the mldsa-native API mldsa_native.h.
2. A secure random number generator implementing randombytes.h
3. Your application source code

Configuration

The configuration file mldsa_native_config.h sets:

• MLD_CONFIG_PARAMETER_SET: Security level (default 65)
• MLD_CONFIG_NAMESPACE_PREFIX: Symbol prefix (set to mldsa)
• MLD_CONFIG_USE_NATIVE_BACKEND_ARITH: Enables native arithmetic backend
• MLD_CONFIG_USE_NATIVE_BACKEND_FIPS202: Enables native FIPS-202 backend

Notes

• Both mldsa_native.c and mldsa_native_asm.S must be compiled and linked
• Native backends are auto-selected based on target architecture
• On unsupported platforms, the C backend is used automatically

Usage

make build   # Build the example
make run     # Run the example

Warning

The randombytes() implementation in test_only_rng/ is for TESTING ONLY. You MUST provide a cryptographically secure RNG for production use.
