About PQShield

Originating from the University of Oxford, PQShield are specialists in Post-Quantum Cryptography. We provide quantum-secure cryptographic solutions for software, software/hardware co-design and data in transit. This is particularly important where long lifecycle, performance and lasting confidentiality are a priority, now and for years to come.

We need to be prepared for the threat landscape of the future. Consider the proliferation and lifecycle of connected systems across telecoms, automotive, smart environments and financial institutions – the need for advanced post-quantum protection is evident.

During the transition from older cryptographic standards to new post-quantum cryptography, interoperability with legacy systems is important. Our solutions provide fast time to market and compliance with both existing and upcoming cryptography standards.


A post-quantum System on Chip crypto co-processor toolkit. Full system emulation and standard development tools ease adoption. Available as modular IP or self-contained solution.

Comprising of implementations of post-quantum primitives fully integrated with OpenSSL API and applications such as PKI (CA), S/MIME electronic mail and VPN solutions.

A software development toolkit for enabling ‘data in transit’ messaging solutions using post-quantum algorithms, leveraging a new, provably secure, Signal-derived protocol.
