Dr. James Howe Cryptographic Engineer and Researcher



I’m a cryptographer, with a focus on practical implementations, cryptanalysis, and protocols. You can find a link to my publications on Google Scholar.

I am currently a Senior Research Scientist in the Quantum Security Group at SandboxAQ.

For 2.5 years, I was employed as a Cryptography Engineer at PQShield Ltd, a small spin-out company from the University of Oxford. Previously, I was a post-doc at the University of Bristol in the SCA / Crypto group and at CSIT where I also did my PhD. Other previous research positions and education history can be found in my CV.

Research Interests

The focus of my research is mainly based around (but not limited to) post-quantum cryptography. My research has somewhat been focused on implementations (optimisations for hardware and software designs), physical implementation attacks (side-channel and fault attacks) and countermeasures. Also I have been researching protocols (such as KEMs, signatures, and beyond) and algorithmic optimisations.
