Post-quantum cryptography is based on different mathematical foundations than traditional “number theoretic” based RSA and Elliptic Curve algorithms. Quantum-resistant lattice-based, code-based, and multivariate-based algorithms do not benefit from the hardware acceleration features available in traditional smart cards and secure elements. As a post-quantum pioneer, PQShield has a deep understanding of the computational and mathematical requirements of these new algorithms which has led to significant architectural and design innovations in our hardware implementations.

What is PQSoC?

PQSoC crypto co-processor summary

PQSoC is a configurable “System on Chip” design built from PQShield’s modular IP cores, offering features and functionality suitable for smart cards and other hardware-based secure elements.

PQSoC components have been designed to implement upcoming post-quantum cryptographic standards — while also offering efficient interoperability with legacy algorithms.

Available as both a modular IP or self-contained solution, it is FIPS 140-3 ready and side-channel attacks resistant.


Hardware Components

RISC-V crypto co-processors

RISC-V Controller: standards compliant but designed for security. PQShield actively contributes to RISC-V ISA and TRNG.

Custom PQC co-processors: designed to support all new PQC standards. They drastically reduce latency and power consumption of post-quantum cryptography computations.

Secondary cryptography co-processor: that supports symmetric encryption algorithms, hash functions (hash-based cryptography), and secure random-number generation.

Peripherals: required for development and testing.

Note: The components are also offered separately; it is possible to integrate the cryptographic coprocessors with proprietary CPU cores (such as those from Intel or ARM).

Software Components

Crypto co-processor software component

PQSLIB. A library of post-quantum cryptographic primitives that utilizes the special hardware features offered by PQSoC. These low-level primitives can be used to replace or complement legacy cryptography in applications. The implementations match current NIST post-quantum standardization finalists for digital signatures, key establishment and encryption, and are constantly updated as the process nears completion.

PQSE. A full system emulator that allows efficient application development and debugging. The emulator covers both the CPU core and the cryptographic peripherals, so applications can be tested at near-real time speeds without resorting to hardware circuit simulation.
