题目：Privacy Preserving Genomic Data Query and Heterogeneous Network Coexistence Empowered by Advanced Physical Layer Techniques
主讲人：Yantian Hou, Assistant Professor, Boise State University, USA
Secure cloud-based medical data analysis requires data aggregation from distributed data sources, thus incurring data privacy concerns. Privacy-preserving genomic data analysis has been shown critical in biomedical therapy. However, it is a challenging task due to the high privacy sensitivity of genomic data and the large size of genomic sequence. Multiple previous works have been pursuing privacy and efficiency in genomic data analysis. In our work, we target at securely search top-k most similar genomic sequences using edit-distance metric aggregated from multiple data owners. Our approach could guarantee privacy of data, query, and access patterns. Approximated solutions are proposed to extensively improve search efficiency while maintaining search result accuracy.
We are facing the spectrum deficiency problem today due to the proliferation of wireless devices. It is always an open problem to enable heterogeneous devices coexisting within the same collision domain. The problem is even harder to tackle for heterogeneous devices running different physical-layer protocols. In our work, we resort to several advanced physical techniques such as wireless MIMO and reconfigurable antennas. We formulate the characteristics brought by these techniques into our model, based on which we analyze the theoretical performance bound and derive the optimal scheduling, beamforming, and reconfigurability solutions in general multi-hop heterogeneous networks.

题目: New Frontiers in Cloud Computing for Big Data and Internet-of-Things (IoT) Applications 主讲人：Prof. Rajkumar Buyya，Director, Cloud Computing and Distributed Systems (CLOUDS) Lab, The University of Melbourne, Australia
Computing is being transformed to a model consisting of services that
are commoditised and delivered in a manner similar to utilities such as
water, electricity, gas, and telephony. Several computing paradigms have
promised to deliver this utility computing vision. Cloud computing has
emerged as one of the buzzwords in the IT industry and turned the vision
of "computing utilities" into a reality. Clouds deliver infrastructure,
platform, and software (application) as services, which are made
available as subscription-based services in a pay-as-you-go model to
consumers. Cloud application platforms need to offer (1) APIs and tools
for rapid creation of elastic applications and (2) a runtime system for
deployment of applications on geographically distributed computing
infrastructure in a seamless manner.
The Internet of Things (IoT) paradigm enables seamless integration of
cyber-and-physical worlds and opening up opportunities for creating new
class of applications for domains such as smart cities. The emerging Fog
computing is extending Cloud computing paradigm to edge resources for
latency sensitive IoT applications.
This keynote presentation will cover (a) 21st century vision of
computing and identifies various IT paradigms promising to deliver the
vision of computing utilities; (b) opportunities and challenges for
utility and market-oriented Cloud computing, (c) innovative architecture
for creating market-oriented and elastic Clouds by harnessing
virtualisation technologies; (d) Aneka, a Cloud Application Platform,
for rapid development of Cloud/Big Data applications and their
deployment on private/public Clouds with resource provisioning driven by
SLAs; (e) experimental results on deploying Cloud and Big
Data/Internet-of-Things (IoT) applications in engineering, and health
care, satellite image processing, and smart cities on elastic Clouds;
and (f) directions for delivering our 21st century vision along with
pathways for future research in Cloud and Fog computing.
