Cryptography

Offering an arsenal of techniques to provide effective protection against the increasing cyber threat, cryptography is an integral part of many of our research projects.

Overview

With outstanding expertise in this field, we focus on advanced techniques and applications such as high-function encryption schemas and digital signatures, authentication and key exchange protocols, and cryptographic solutions for privacy-preserving identity management, secure data sharing and information exchange.

Global authority on cryptography

Professor Liqun Chen, leads the research into hardware security and cryptography. Previously a principal research scientist in the Security and Manageability Laboratory at Hewlett Packard Labs, Professor Chen has invented or co- invented cryptographic solutions which have been incorporated into international standards and used in applications millions of people use every day.

Student projects

Our PhD students are conducting an important body of research in the field of cryptography, with a number sponsored by external companies and government. Two students are collaborating with ObjectTech – a company aimed at delivering ‘seamless travel’ through airports, borders and events – to explore lattice-based cryptography for blockchain applications, making them more secure against future technological advances.

Other student projects are focused on post-quantum cryptography research, developing algorithms resistant to attacks by quantum computers which will be required by Trusted Platform Modules in the future.
