Xueqiao Liu, PhD student from the School of Computing and Information Technology recently attended the 13th International Conference on Provable and Practical Security (PROVSEC 2019) in Cairns, Australia.

Xueqiao reflects on his attendance, ‘The theme of the conference not only kept emphasizing the importance of “Provable Security” as a tool of measuring the security of cryptographic primitives as usual, but valued “Practical Security”  due to the ubiquitous cyber security technologies as well. As we know, the development of quantum computing threatens the security of cryptosystems built based on the traditional number theory assumptions. Cryptosystems which are proved secure under traditional hard problems may not be able to effectively defend quantum attacks.’

‘Professor Steven Galbraith from University of Auckland, New Zealand delivered a interesting keynote speech titled “Open Problems and Challenges in Post-Quantum Cryptography” which gave audiences a fast glance at the research problems and research gaps of post-quantum cryptography, especially challenges in the design of post-quantum signature schemes, which include short public key, short signature, and fast signing and verification. This speech provides cryptography researchers with a brief introduction to the fundamentals of post-quantum cryptography and may inspire us to construct post-quantum signature schemes with better experimental performance.’
