Professor Ivan Stojmenovic University of Ottawa |
| Title: Green Computing in Mobile Cloud |
| Abstract:
Cloud computing and green computing came to
be hot topics in recent years, especially in data center
networks. As the development of smart phones and tablets, the
combination between mobile devices and cloud computing, named by
mobile cloud, has emerged as a new cloud computing platform,
bringing new challenges to cloud and green computing. One of the
most important issues is how to optimize the scheduling and
transport schemes for mobile devices to achieve energy saving. In this talk, I will first introduce the development of mobile cloud computing. Next, I will present the new challenges of green computing in mobile cloud; especially highlight the uniqueness, compared with the study on the energy saving problem in wireless networking. I will also discuss the possible solutions from various perspectives, including task scheduling, access management, transport mechanisms and application optimization. |

| Title: Sensors Nets and their Analysis in the Cloud |
| Abstract:
We discuss the conventional wisdom with light weight clients supported by backend clouds and the implications for power efficient user friendly computing. We apply this to scientific data analysis in remote regions (in particular polar science) robotics and surveillance. We introduce a new sensor-cloud interface based on publish-subscribe technology. We discuss how this can be prototyped on FutureGrid. We define a sensor as any data source producing a time series and point out the generality of this. |

Professor Vijay Varadharajan Macquarie University Australia |
| Title: Secure and Trustworthy Computing |
| Abstract:
Security and dependability have become particularly significant as systems get more and more interconnected and as their complexity increases. Technologies such as distributed online applications, cloud computing, service oriented architectures, pervasive mobile devices, and social networking have increased the dependency of society and economy on information systems and infrastructures. Along with the phenomenal growth in technology has been the growth in technology related crimes. In this talk, I will start with a brief look at some of the recent developments in the threat scenery. Then I will some key challenges involved in the design of secure and trustworthy systems. In particular, I will discuss the types of security services needed to secure distributed systems and applications and will highlight the issues of trust which underpins security. Then I will consider how traditional security and social aspects of trust can be combined to enhance the quality of security decision making. I will conclude the talk by demonstrating such a trust enhanced security approach using some example systems that we have been working on. |

Professor Bhavani Thuraisingham
Department of Computer Science |
| Title: Cloud-Centric Assured Information Sharing |
| Abstract:
Daniel Wolfe (formerly of the National Security Agency) defined assured information sharing (AIS) as one that ※provides the ability to dynamically and securely share information at multiple classification levels among U.S., allied and coalition forces.§ The DoD＊s vision for AIS is to ※deliver the power of in-formation to ensure mission success through an agile enterprise with freedom of maneuverability across the information environment§. More recently National Security Agency CIO Lonny Anderson has stated that the agency is focusing on a ※cloud-centric§ approach to information sharing with other agencies. To address the needs of the DoD, our project is developing technologies and tools for cloud-centric assured information sharing funded by the Air Force Office of Scientific Research (AFOSR). We initially examined developments in grid and cloud computing and explored security issues. In particular, we explored secure virtualization, secure storage, secure data management and secure cloud monitoring. We also developed a secure cloud data manager that will be utilized as the engine for assured information sharing. We developed two types of cloud data managers, one based on semantic web data and the other based on relational data. Current frameworks do not scale for large RDF graphs and as a result do not address these challenges. Here, we developed a framework using Hadoop to store and retrieve large numbers of RDF triples by exploiting the cloud computing paradigm. We developed a scheme to store RDF data in a Hadoop Distributed File System. More than one Hadoop job may be needed to answer a query because a triple pattern in a query cannot take part in more than one join in a Hadoop job. To determine the jobs, we developed algorithms to generate a near optimal query plan based on a greedy approach to answer a SPARQL Protocol and RDF Query Language (SPARQL) query. We use Hadoop＊s MapReduce framework to answer the queries. We implemented XACML-based policy management and integrated it with our query processing strategies. For secure query processing for relational data we utilized the HIVE framework. In addition to secure query processing, we also developed encrypted query processing on the Amazon cloud that interfaced to the Intelligence Community＊s BlackBook system. More recently we have developed strategies for secure storage and query processing in a hybrid cloud, In particular, we have developed algorithms for query processing wherein user＊s local computing capability is exploited alongside public cloud services to deliver an efficient and secure data management solution. Hybrid clouds offer numerous advantages including ability to restrict data and processing being out-sourced based on sensitivity/confidentiality of the data as well as control on the monetary expenses of using cloud services by exploiting local resources. Nonetheless, query processing in hybrid cloud introduces new challenges, namely, 1) data design: How to partition relations between the public and private components of the cloud? The solution must account for the sensitivity of attributes in a relation as well as the workload that will be executed; 2) data security: How to represent encrypted (sensitive) data that enables non-trivial query processing on the public cloud? and 3) query processing: How to execute queries over the distributed data with mixed representation (i.e., encrypted and plaintext) while minimizing processing and communication costs? This paper addresses these challenges and incorporates the respective solutions into an add-on tool for a Hadoop and Hive-based cloud computing infrastructure. We have also developed demonstration systems with our European partners: Kings College, University of London and the University of Insubria Italy who are funded by EOARD (The European Office of Aero-space Research and Development). The first demonstration illustrates how information may be shared in our cloud, based on policies specified in XACML. In the second demonstration we are implementing a semantic web-based policy engine and will show how multiple social networks may share information on our cloud based on semantic web-based policies. For both demonstrations, we will use the secure cloud data managers we have implemented. 2 We have also made progress on a number of research areas related to the cloud. These include (i) SPARQL/JENA-based inference controller for provenance data. This inference controller is being implemented on our Hadoop Cloud; (ii) Cloud-based Malware Detection for Evolving Data Streams where we have developed a scalable feature selection and extraction solution that leverages a cloud computing framework; and (iii) CloudMask: Together with Purdue University we have developed CloudMask, an approach that supports fine-grained attribute-based access control based on encryption while at the same time assuring the privacy of the identity attributes of the users accessing the data. Our future plans include secure virtualization using the XEN hypervisor to host our cloud data managers and demonstrate assured information sharing on this platform. We would also like to explore collaboration with the Asia Pacific region (which includes Australia) for cloud-based information sharing demonstrations with fund-ing from AOARD (The Asian Office of Aerospace Research and Development). |

Professor David Abramson Monash University Australia |
| Title: Mixing Cloud and Grid Resources for High Throughput Science |
| Abstract:
Over the past 15 years we have developed
a sophisticated tool set for solving large parameter sweep and
search applications. This tool family, called Nimrod, makes it
easy to create computational experiments in which multiple
independent scenarios are explored. Nimrod supports complete
state-space exploration (so called full parameter sweeps),
guided search (using non-linear optimisation techniques) and
design-of-experiment schemes (for reducing the search space).
All of these work by creating many tasks, and farming them out
to computational units distributed (potentially) over a Grid. We
have run many real world case studies over local clusters and
the Grid. |

Professor Albert Zomaya Director, Centre for Distributed and High Performance Computing University of Sydney Australia |
| Title: Environmentally Sustainable Large Scale Distributed Systems |
| Abstract:
Global warming and climate change trends call for urgent action to manage information and communication technologies in a sustainable manner by minimizing energy consumption and utilizing resources more efficiently. Distributed computing environments have become the de facto platforms for many applications. These systems bring a range of heterogeneous resources that should be able to function continuously and autonomously. However, distributed systems expend a lot of energy which raises a range of important research issues related to the use and virtualisation of ICT resources in a way offers significant potential to contribute to the goal of what has been described as ＆green computing＊. This talk will review some of the important questions related to the development of new algorithms and tools for energy每aware resource management allocation for large每scale distributed systems enabling these systems to become environmentally friendly. |
