My Fifty Years of Cryptography: the Evolution of Cryptographic Standards
(3 July 9.30am)
Presenter: Emeritus Professor Jennifer Seberry, IC2, University of Wollongong, Australia
Abstract: Today, e-commerce and the internet occupy everyone’s mind — merchants, programmers, bankers, consumers and teenagers. A few years ago, the then-fledgling industry was struggling to convince the public to make purchases and do financial transactions online. A key element that the industry needed to address was the public’s concern about the security of online processes and transactions. The science of modern cryptography — a field based on advanced mathematical concepts that include number theory and group theory — was identified as a vehicle for securing public confidence in the safety of e-commerce transactions. The effective application of cryptographic mathematics to e-commerce has proved to be a key factor in its current level of acceptance. Modern cryptography is a relatively new field. Before 1970, the world of encrypting and decrypting messages was primarily a black art practiced by government security agencies and the military without a consistent framework. The early to mid-1970s saw the emergence of mathematical cryptography, which provided a robust theoretical framework for encryption and decryption that enabled cryptographers to predict the security of the message.
Bio: Dr Seberry is an Emeritus Professor and Former Head, Department of Computer Science, as well as Former Director, Centre for Computer Security Research, University of Wollongong. She graduated PhD in Computation Mathematics from La Trobe University in 1971. She has subsequently held positions at the Australian National University, The University of Sydney and University College, The Australian Defence Force Academy, The University of New South Wales. She has published extensively in Discrete Mathematics and is world renown for her new discoveries on Hadamard matrices, orthogonal designs and statistical designs. In 1970 she co-founded the series of conferences known as the xxth Australian Conference on Combinatorial Mathematics and Combinatorial Computing. She started Teaching in Cryptology and Computer Security in 1980. She is especially interested in cryptographic algorithms, authentication and privacy, In 1987 at University College, ADFA, she founded the Centre for Computer and Communications Security Research to be a resevoir of expertise for the Australian community. Her studies of the application of discrete mathematics and combinatorial computing via bent functions, S-box design, has led to the design of secure crypto-algorithms and strong hashing algorithms for secure and reliable information transfer in networks and telecommunications. Her studies of Hadamard matrices and orthogonal designs are applied in CDMA technologies. In 1990 she founded the AUSCRYPT/ASIACRYPT series of International Cryptologic Conferences in the Asia/Oceania area. She has supervised 31 successful PhD candidates, has over 450 scholarly papers and eight books.
Advanced Forward and Backward Searchable Symmetric Encryption
(3 July 2.30pm)
Presenter: Professor Joseph K. Liu, Monash University, Australia
Abstract: In this talk, we will cover the state-of-the-art techniques for searchable symmetric encryption that can achieve forward and backward security, which can enhance the dynamic encrypted database from suffering attacks such as file injection attack. Our techniques not only provide enhanced security but also achieve a practical level of efficiency, by using symmetric primitives only. We will incorporate our findings from our most recent publications (including CCS 2018 and ESORICS 2019) into this talk.

The Fourth Industrial Revolution and Blockchain Technology
(4 July 9.30am)
Presenter: Professor Jong Sou Park, Korea Aerospace University, Korea
Abstract: We expect the Fourth Industrial Revolution will change so many things. But we really do not understand what the Fourth Industrial Revolution is. In this talk, we want to talk about Blockchain Technology and Federated Learning. The Federated Learning offers a very promising future for privacy enhanced edge level A.I. with Blockchain smart contract. Maybe, this Federated Learning can bring real impact on the Fourth Industrial Revolution.

Machine Learning in the Hands of a Malicious Adversary: The Threat of AI-Driven Smart Malware
(4 July 1.30pm)
Presenter: Professor Zbigniew Kalbarczyk, University of Illinois at Urbana-Champaign, USA
Abstract: Targeted and sophisticated cyber-attacks are on the rise. Attackers spend a significant amount of time preparing attacks (including reconnaissance, weaponization, and exploitation), which require them to retain a lasting foothold in the target system to collect the intelligence necessary to seize control of the victim’s system. To avoid being exposed while performing those activities, highly sophisticated adversaries may employ AI-driven methods to accomplish the task of preparing an attack strategy and triggering the execution of a malicious payload. In this talk, we discuss the security threat of AI-driven smart malware. Specifically, we consider a scenario in which machine learning models can be embedded into malware that, upon installation, learns the details of the victim system, infers attack strategies based on live operational data, and triggers an attack at the most opportune time so as to maximize the impact. We illustrate this threat in the context of two safety-critical cyber-physical systems (CPS): (i) a surgical robot, for which we consider a robot-supported haptic feedback rendering algorithm as an application, and (ii) a smart building, for which we consider a CPS that manages and controls the environment in which a major computing enterprise (e.g., a high-performance computing system or a cloud infrastructure) operates. We show how smart malware can be developed and used to compromise the critical functionalities/services provided by the CPS with dire consequences for patients (in the case of the surgical robot) or a large computing infrastructure (in the case of the smart building).
