Title: A View on Blockchains, Their Applications, and an Informal Evaluation


WhenFriday, 26th October 2018 at 11:30am - 12:30pm


Speaker live from:Computer Science and Engineering Building (K17), Level 1 Meeting Room 113, Sydney, NSW




Although these days blockchains are very often referred to as "Blockchain Technology", they simply denote a well-defined Abstract Data Type, which is based on a linked list of data elements, each of which being linked by cryptographically constructed linkages. Thus, this talk will enlighten the core technical characteristics of blockchains from a slightly unusual angle, while indicating an evolutionary computer science approach undertaken - enriched with security, networking, and distributed systems mechanisms.Also, the talk will raise the awareness that blockchans and related distributed ledgers assume important prerequisites, which result in dedicated effects and impacts from which different applications (a) can benefit, (b) other may benefit with dedicated support only, and (b) even others will not benefit at all.Unfortunately, many projections of the usefulness and applicability of blockchains remain unrealistic, therefore, selected and major technical challenges and more broader risks foreseen will conclude the talk in terms of an informal evaluation.



Prof. Dr. BurkhardStilleris a full professor for Communication Systems at the University of Zürich UZH, Switzerland with over 20 years of networking experience. He started to work on Bitcoins and blockchains in early 2014 with his by then PostDoc Dr. Thomas Bocek.Besides being the coordinator of many Swiss and European industrial and research projects, he is Editor-in-Chief of Elsevier’s Computer Networks journal, he organized major conferences (e.g., IFIP Networking 2018, CNSM 2013, IEEE LCN 2009), and has published within his main research interests well over 250 research papers on systems with a fully decentralized control (blockchains, clouds, peer-to-peer), network and service management (economic management), Internet-of-Things (security of constrained devices, LoRa/TTN), and telecommunication economics (charging and accounting).He is a senior advisor of, an ICO-financed start-up in the blockchain and logistics domain, the IFIP TC6 Chair (Technical Committee on Communication Systems), and member of the Luxembourg FNR Research Council.

Seminar: A Changing Landscape: Securing the Internet of Things (IoT)

Speaker: Professor Sanjay K Jha

Director, Cybersecurity and Privacy Laboratory (Cyspri), UNSW


When: Wednesday 1 June, 2016, 4:00-5:00pm

Where: The University of Sydney, School of IT Building, SIT Lecture Theatre (Room 123), Level 1



First part of this talk will discuss how the community is converging towards the IoT vision having worked in wireless sensor networking and Machine-2-Machine (M2M) communication. This will follow a general discussion of security challenges in IoT. Finally I will discuss some results from an ongoing projects on security of bodywork devices and IoT. Wireless bodyworn sensing devices are becoming popular for fitness, sports training and personalized healthcare applications. Securing the data generated by these devices is essential if they are to be integrated into the current health infrastructure and employed in medical applications. In this talk, I will discuss a mechanism to secure data provenance and location proof for these devices by exploiting symmetric spatio-temporal characteristics of the wireless link between two communicating parties. Our solution enables both parties to generate closely matching `link' fingerprints, which uniquely associate a data session with a wireless link such that a third party, at a later date, can verify the links the data was communicated on. These fingerprints are very hard for an eavesdropper to forge, lightweight compared to traditional provenance mechanisms, and allow for interesting security properties such as accountability and non-repudiation. I will present our solution with experiments using bodyworn devices in scenarios approximating actual device deployment. I will also touch upon other research on secure reprogramming of IoT devices over wireless networks.

One-day tutorial by Prof. Ponnurangam Kumaraguru on "Privacy and Security in Online Social Media"
24th February 2016


Speaker: Associate Professor Ponnurangam Kumaraguru, Indraprastha Institute of Information Technology, Delhi
Title: Privacy and Security in Online Social Media
Date: Wednesday 24 February 2016
Time: 10:00 – 11:30, 12:00 – 13:30
Location: CSE Seminar room (K17_113), Level 1, CSE Building (K17).
Hosts: Prof. Sanjay Jha, Director Cybersecurity and Privacy Lab, UNSW and Dr Dali Kaafar, Research Group Leader, Networks Group, Connecting to the World Program, DATA61 | CSIRO


Tutorial Description:

With increase in the usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, YouTube, Orkut, Twitter, Flickr, Google+, FourSquare, Pinterest, and the likes have changed the way the Internet is being used. Privacy and security of online social media need to be investigated, studied and characterized from various perspectives (computational, cultural, psychological, etc.). It is critical to detect security threats and defend privacy through real-time and scalable systems. Since there are no logical boundaries for the social media, it is important to study the problem from an international perspective too.

Topics to be covered:
+ Trust, credibility, and reputations in social systems
+ Detection and characterization of spam, phishing
+ Information privacy disclosure, revelation and its effects in OSM and online social networks
+ Tracking social footprint / identities across different social network

About Ponnurangam Kumaraguru, relevant to this Tutorial:

Seminar: Cyber Security Tomorrow: What are the Long-Term challenges?

Seminar by Prof Andrew Martin from Oxford on "Cyber Security Tomorrow: What are the Long-Term challenges?" 2nd Dec'15

Title: Cyber Security Tomorrow: What are the Long-Term challenges?
Speaker: Prof. Andrew Martin, University of Oxford
Date: Wednesday, December 2nd, 2015
Time: 11am - 12pm
Venue: K-J17-G02 - Ainswth G02
Host: Prof. Sanjay Jha, Director CySPri

Cyber Security often seems to be dominated by short-term concerns, because there are a great many issues that need immediate resolution. Simultaneously, many seem to expect that this will be a running theme for many years to come: the underlying problems and challenges show no sign of reaching a firm resolution. The reason for this seems to lie in the relative immaturity of software engineering as a discipline -- even forty years after its foundation -- and also in the way that cyberspace has become a part of everyday reality for most people in the developed world (and for many in the developing world too), reconfiguring social norms as it becomes ever-more pervasive. Meeting these challenges appears to require a profound shift in the education of technologists -- but also in the way we conceive of society and the interactions in which everyone participates.

Prof. Andrew Martin undertakes research and teaching in the area of Systems Security, in the University of Oxford. He conceived the University's new Cyber Security Centre and helps to direct it, leading the University's successful bid to be recognised as a Centre of Excellence in Cyber Security Research. He directs the new Centre for Doctoral Training in Cyber Security, which admits 17 students each year for inter-disciplinary education and research. His recent research focus has been on the technologies of Trusted Computing, exploring how they can be applied in grid and cloud computing contexts, as well as in mobile devices, in order to address their emerging security challenges. Andrew wrote a doctoral thesis on the subject 'Machine-Assisted Theorem Proving for Software Engineering', in the early 1990s. He then worked as a Research Fellow in the Software Verification Research Centre at the University of Queensland, Australia. Returning to the UK, he was briefly a lecturer at the University of Southampton, before returning to Oxford to take up his present post in 1999. Dr Martin is a fellow of Kellogg College, Oxford. He is presently the supervisor for seven doctoral students, and holds several research grants, details below.
