Keynote Talk: The Case for Human Primacy in Cryptography
In the history of adversarial technologies, cryptology has the unique distinction of offering an exponential advantage to the defence over the offence, as long as it is done right and, crucially, the defence is not otherwise compromised. In this talk, I will review the “clouds” gathering over the trustworthiness of our computing landscape, and argue on that basis that our community should strive for security and privacy models that give absolute primacy to humans, rather than electronic surrogates. Toward that aim, I will, inter alia, demonstrate an early but promising approach to asymmetric encryption decipherable entirely by a human, and discuss the implications for a nascent field of human cryptography.
Xavier Boyen is an ARC Future Fellow and Associate Professor at QUT in Brisbane, Australia. Xavier has previously held positions in the security industry and academia in the US and the EU, after completing a PhD at Stanford in 2003. He has contributed several cryptosystems adopted in products and IEEE and IETF standards, and about 2^6 scholarly papers earning 2^13 to 2^14 citations. Xavier‘s current personal quest for a “paradigm shift” is to bring cryptography back to us humans, to serve as our personal ultimate root of trust.

Keynote Talk: Time for a Paradigm Shift in Our Disciplinary Culture?
It is very easy to make serious mistakes in cryptography, as I will illustrate by my own extremely poor judgment about curve selection in the early years of elliptic and hyperelliptic curve crypto. I will then give two examples of important work on real-world security vulnerabilities that have been largely ignored or dismissed by the crypto research community simply because those security properties were not included in decades-old theoretical security models that continue to enjoy almost universal acceptance despite their inadequacies. Then I will talk about the pernicious social influences on conduct in our profession, starting again with two examples of my own succumbing to bad temptations, and then continuing with examples of less than admirable behavior by some leading researchers. The big question is whether our community can return to the traditional values of intellectual thought and scientific research, foremost among which is humility. I will conclude with a suggestion for a paradigm shift in our disciplinary culture.
Neal Koblitz has been in the Mathematics Department of the University of Washington since 1979, and has worked in cryptography since 1985. He is the author of six books, of which the last, “Random Curves: Journeys of a Mathematician”, is autobiographical. He and his wife Ann direct the Kovalevskaia Fund, which supports women in science in developing countries. He has had close relations with the Vietnamese mathematical community for four decades, since shortly after the end of the American war against that country.
