The KiviPQC-KEM is a hardware accelerator designed to execute post-quantum cryptographic operations efficiently. It specifically implements the Module Lattice-based Key Encapsulation Mechanism (ML-KEM) as standardized by NIST in FIPS 203, facilitating the secure exchange of shared secret keys over public channels. This engine supports key generation, encapsulation, and decapsulation, making it suitable for both client and server sides of a key exchange. Built on a RISC-V-like SoC topology, it features an AMBA AXI4-Lite interface for straightforward integration into ASICs or FPGAs. The IP is available in two versions—Fast (F) for performance and Tiny (T) for low area usage—ensuring flexibility for various system resource requirements while maintaining protection against timing-based side-channel attacks..
