PQPlatform-Lattice by PQShield Ltd provides post-quantum support for NIST-standardized algorithms with minimal area, leveraging an existing SHA-3 accelerator powered by PQShield firmware. It is designed for minimal area and maximum compatibility, with optional firmware-backed side-channel resistance. PQPlatform-Lattice is a building block for hardware systems, deployable on small-area devices with firmware-backed side-channel countermeasures. It supports lattice-based post-quantum cryptography, including digital signatures and key establishment, and is optimized for high-throughput performance in network hardware applications or HSMs requiring fast performance. PQPlatform-Lattice is ideal for smaller key sizes and high signature verification throughput, making it suitable for resource-constrained environments.
