Joseph visited the DIoT cluster on 20th July 2018!


Joseph Liu, has established the Monash Blockchain Research Lab.
I invited Joseph from Monash who has done a lot of work in Blockchain.

He gave a talk



Title: Privacy-Preserving Techniques to Blockchain: The Ring Signature Approach

Abstract: Ring signature is a kind of anonymous signature. Verifier only knows that the signer is a user within a group, yet does not know the identity of this signer. In this talk, we will cover the basics of ring signature and linkable ring signature, including the concept, applications, technical constructions and variants. We will further relate linkable ring signature to cryptocurrencies and discuss how it can provide privacy to users in Blockchain. We will also discuss some interesting future works in this area.

Biography: Joseph Liu is a senior lecturer in the Faculty of Information Technology, Monash University. He got his PhD from the Chinese University of Hong Kong at 2004. Prior to joining Monash at 2015, he has worked as a research scientist at Institute for Infocomm Research (I2R) in Singapore for more than 7 years. His research areas include cyber security, blockchain, applied cryptography and privacy enhanced technology. He has established the Monash Blockchain Research 
Lab at October 2017 and serves as the director since then. His remarkable research in linkable ring signature forms the theory basis of Monero (XMR), one of the largest cryptocurrencies in the world. He has been given the Dean's Award for Excellence in Research Impact in 2018, for his contribution to the blockchain community.

Arkady presented at the last meeting - 18 May 2018

Here comes Arkady's presentation at Deakin last Friday: https://drive.google.com/open?id=1t-Px1WTyPmPEYukV5Tg-XB9UuWVNtC1O   Title: Challenges and opportunities of IoT silos interoperability Abstract : After initial hype with deploying IoT platforms in various applications and building IoT silos, the IoT research community realised the need for IoT interoperability frameworks and building IoT ecosystems as the next step in IoT evolution. This talk will focus on the challenges and opportunities of IoT interoperability with highlights into OpenIoT platform which pioneered horizontal integration of IoT silos and EU Horizon-2020 project bIoTope – building IoT open innovation ecosystem for connected smart objects. The bIoTope ecosystem is based on everything-as-a-service (XaaS) driven by run-time context, reasoning about situations, semantics, continuous analytics. The primary application domain of biotope is Smart Cities. Bio : Professor Zaslavsky is a Senior Princ

Agenda and brief notes from 15 June DIoT cluster meeting

We started by going over the capabilities matrix and talking about some current projects. Then, Chandan talked about the iot festival. Agenda: 1. http://iotfestival.io/ Morshed, Chandan, Mohamed, and Lei + others who attended – perhaps you could give us a run-down of what happened? Any highlights/updates from the IoT world out there Further funding opportunities: a. Alibaba research funding sources now accepting proposals: USD50K-100K for a one-year project, dateline 1 st of July, multiple proposals from the same institution can be funded, there is an IoT edge computing topic mentioned - click on Research Area tab and then IoT, and download the description from: https://102.alibaba.com/fund/proposalAbout.htm (past projects here: https://102.alibaba.com/fund/proposalResult.htm ) (there are also topics in ML) (maybe we could all write a proposal each? J Or try to write/lead a proposal if you have an idea (e.g., it could be an extension of y
