Quantum-Safe Security from Software to Silicon

PQSecure Technologies provides U.S.-designed post-quantum cryptography software and hardware solutions that help government organizations protect sensitive information, embedded platforms and critical infrastructure against current and emerging cryptographic threats. Our technology enables agencies and their industry partners to transition from legacy public-key cryptography to NIST-standardized post-quantum cryptography while maintaining the performance, security and crypto-agility required by mission-critical systems.

PQSecure offers a comprehensive portfolio spanning software libraries, FPGA implementations, ASIC intellectual property and SoC-integrated cryptographic accelerators. Our solutions support NIST post-quantum algorithms including ML-KEM, ML-DSA and SLH-DSA, together with complementary symmetric cryptography, hashing, random-number generation and Root-of-Trust capabilities. This allows customers to implement quantum-safe security across software-only systems as well as hardware-accelerated and hardware/software co-design architectures.

A key differentiator is PQSecure's focus on implementation security. Cryptographic algorithms can be mathematically secure yet remain vulnerable when implemented in physical devices. PQSecure develops software and hardware with protections against side-channel attacks such as power, electromagnetic and timing analysis, as well as fault-related threats where required. These capabilities are particularly important for defense, aerospace, space, IoT, OT and other systems deployed in physically accessible or adversarial environments.

Government applications include quantum-safe secure boot, firmware authentication, secure software updates, device identity, key establishment, secure communications and hardware Root of Trust. PQSecure technology can be incorporated into tactical radios, unmanned systems, satellites, sensors, industrial controllers, secure processors, communications equipment and other embedded platforms.

As the United States increases its focus on post-quantum migration, secure microelectronics and trusted semiconductor supply chains, the provenance of security-critical IP is increasingly important. PQSecure provides U.S.-designed cryptographic IP that can be integrated into domestically manufactured or trusted semiconductor platforms, supporting broader CHIPS-era objectives for secure and resilient microelectronics.

PQSecure helps public-sector organizations move beyond PQC planning toward deployable, validated and crypto-agile quantum-safe systems, providing a migration path from software prototypes through FPGA deployment and ultimately ASIC and SoC integration.
