Talk Title: Towards Decentralized Privacy-Preserving Cryptocurrency with Accountability
Talk Abstract:

Blockchain-based cryptocurrencies such as Bitcoin provide a way to construct decentralized payment systems without the need of any trusted parties. However, these cryptocurrencies inherent the transparent feature of blockchain and thus lack privacy. To tackle this problem, considerable efforts have been devoted to the development of privacy-preserving cryptocurrencies. Examples, including Monero and Zcash, employ advanced cryptographic primitives to provide user privacy.

However, strong privacy is a double-edged sword. It is difficult, if not impossible, to apply typical compliance measures to these cryptocurrencies. Consequently, cryptocurrencies could be abused for illegal activities such as blackmailing or money laundering. In this talk, we present our recent effort in the development of a decentralized cryptocurrency supporting privacy and accountability. In particular, we will present mechanisms to support various compliance measures while maintaining privacy. Finally, we will conclude the talk with insights developed from our experience.

Talk Title: Internet of Things (IoT) Security and Forensics: Challenges and Opportunities
Talk Abstract:

Internet of Things (IoT) devices are becoming commonplace in our society, due to their widespread applications (e.g., environmental monitoring, smart cities, healthcare, surveillance, and battlefields such as Internet of Battlefield Things). Such devices are also generally capable of capturing a broad range of information, including digital artifacts that can be used for cyber threat intelligence and inform security mitigation strategy formulation. There are, however, a number of challenges associated with designing IoT cyber security and threat intelligence solutions. In addition to the technical challenges, there are also associated legal and policy challenges that need to be considered in the design and deployment of such solutions in practice.

In this presentation, we will explore the challenges from technical, legal and policy perspectives. For example, how do we use machine/deep learning to facilitate detection of real-time attacks against IoT devices and systems, and how can we automatically identify and collect digital evidence in a forensically sound manner which can be subsequently used for cyber threat intelligence? In the event that the attackers use sophisticated tools to obfuscate their trails, can we design machine/deep learning techniques to unobfuscate and/or identify and exploit vulnerabilities to get access to digital evidence? What are the potential legal implications and challenges? Can we also design explainable AI techniques to facilitate the explanation and inclusion of such digital evidence and cyber threat intelligence in court proceedings or presentations to C-level or boards in organizations? Based on these discussed challenges, we will identify potential opportunities for stakeholders in academia (e.g., students and researchers), industry and government.

Talk Title: Robust Trust Management for Open and Distributed Networks
Talk Abstract:

Trust, as a soft security mechanism, can protect us from malicious parties who offer us resources or services in open and distributed networks. In this talk, I will briefly introduce the definitions and characteristics of trust. I will also give a few example models of trust. There are many challenges when modeling trust. I will particularly focus on the issue of unfair rating attacks by introducing several different approaches in coping with the unfair rating attacks. Finally, I will bring up several remaining issues that should be addressed for trust models to be robust.
