The KiviPQC-DSA is a hardware accelerator designed to execute the Module Lattice-based Digital Signature Algorithm (ML-DSA), fully compliant with the NIST FIPS 204 standard. This engine manages the secure generation of private/public key pairs, digital message signing, and signature verification, replacing legacy algorithms like RSA and ECDSA. Built on a RISC-V-like SoC topology, it supports all ML-DSA parameter sets (44, 65, 87) and is available in both Fast (performance-optimized) and Tiny (area-optimized) versions. The core features an AMBA AXI4-Lite interface for easy integration into ASICs or FPGAs and includes built-in protection against timing-based side-channel attacks.

Features and Benefits
- Standards Compliance
- Fully compliant with NIST FIPS 204 for the Module Lattice-based Digital Signature Algorithm (ML-DSA).
- Supports all three ML-DSA parameter sets: 44, 65, and 87.
- Performs key pair generation, signature generation, and signature verification.
- Flexible Architecture
- Fast Version (F): Balanced area and enhanced performance, featuring hardware crypto accelerators and a timer module.
- Tiny Version (T): Compact architecture targeting low area without hardware accelerators.
- Security & Protection
- Provides quantum-resistant security suitable for critical infrastructure, firmware signing, and blockchains.
- Designed with a minimal attack surface.
- Includes protection against timing-based side-channel attacks.
- Integration & Resources
- Interface: Communicates via a lightweight AMBA AXI4-Lite Subordinate port.
- Entropy: Includes software RBG but supports custom interfaces for external entropy sources.
- Efficiency: The Tiny version requires less than 8K 4LUTs on widely used Microchip FPGAs (for ML-DSA-87).
- Memory Requirements
- Fast Version: Requires approximately 210KB of memory (RAM/ROM).
- Tiny Version: Requires approximately 216KB of memory (RAM/ROM).
