The KiviPQC-Box is a comprehensive hardware accelerator designed to perform post-quantum cryptographic operations. It implements both the Module Lattice-based Key Encapsulation Mechanism (ML-KEM) for secure key exchange and the Module Lattice-based Digital Signature Algorithm (ML-DSA) for digital signatures, complying with NIST FIPS 203 and FIPS 204 standards respectively. The engine supports all parameter sets for both algorithms and features a multi-mode operation capability. Built on a RISC-V-like SoC topology with a 32-bit processor, it communicates via an AMBA AXI4-Lite Subordinate port for easy integration into ASICs or FPGAs. Two versions are available—Fast (F) and Tiny (T)—offering a balance between performance and area while ensuring protection against timing-based side-channel attacks.
