Ethervation: Innovation of and on the Ethernet platform

Dr. Robert Metcalfe

Cockrell School of Engineering
The University of Texas at Austin
Austin, Texas, USA

ABSTRACT

Innovation sometimes advances in leaps and bounds when robust "platforms" appear. Ethernet's story going back 42 years involves two robust platforms: CMOS according to Moore's Law and TCP/IP/Ethernet according to, well OK yes, Metcalfe's Law. Ethernet began as a Local Computer Network (later LAN) in 1973. Back then it ran at 2.94Mbps and coaxially connected PCs in a building. Now it runs up to 100Gbps in the LAN, has returned to its Alohanet wireless roots as Wi-Fi, and is moving down to serve the coming Internet of Things. Ethernet platform innovation is paced by semiconductors. But then there are the many innovations that have taken place on top of the evolving Ethernet platform. The TCP/IP/Ethernet Internet has gone web, video, mobile, social, cloud, embedded — from mainframes to minicomputers to workstations to PCs to cellphones to things. Some of this innovation can be attributed to the venerable Ethernet business model, which is based on packet switching, de jure standards (IEEE), owned implementations, fierce competition, interoperability, rapid evolution, backward compatibility, build it and they will come. Ethernet is the answer; what is the question?

Stormy Clouds - Security in Distributed Cloud Systems

Professor Muriel Médard

Electrical Engineering and Computer Science Department
Massachusetts Institute of Technology
Cambridge, Massachsetts, USA

ABSTRACT

As massively distributed storage becomes the norm in cloud networks, they contend with new vulnerabilities imputed by the presence of data in different, possibly untrusted nodes. In this talk, we consider two such types of vulnerabilities. The first one is the risk posed to data stored at nodes that are untrusted. We show that coding alone can be substituted to encryption, with coded portions of data in trusted nodes acting as keys for coded data in untrusted ones. In general, we may interpret keys as representing the size of the list over which an adversary would need to generate guesses in order to recover the plaintext, leading to a natural connection between list decoding and secrecy. Under such a model, we show that algebraic block maximum distance separable (MDS) codes can be constructed so that lists satisfy certain secrecy criteria, which we define to generalize common perfect secrecy and weak secrecy notions. The second type of vulnerability concerns the risk of passwords' being guessed over some nodes storing data, as illustrated by recent cloud attacks. In this domain, the use of guesswork as a metric shows that the dominant effect on vulnerability is not necessarily from a single node, but that it varies in time according to the number of guesses issued. We also introduce the notion of inscrutability, as the growth rate of the average number of probes that an attacker has to make, one at a time, using his best strategy, until he can correctly guess one or more secret strings from multiple randomly chosen strings.

CloudNA Workshop

Data Foundries: The Cauldron of the IoT, Clouds and Datacenters

Dr. Masood Mortazavi

Huawei Technologies
US R&D Center
Santa Clara, California, USA

ABSTRACT

The datacenters that form the core engines for transporting, persisting and transforming data are not merely the major building blocks of the "Cloud." They are more akin to "alchemical" data foundries that transform raw bits of data to the gold of information, content and the derived knowledge services that we have come to expect and desire so voraciously. These services help extend our minds and our cognitive powers so we can construct and live in "smarter" learning and living environments. Societies that learn and live smarter will advance faster to give higher meaning to human life and endeavours.

How did these data foundries come into being? What forces gave rise to them? What special problems do they solve? Why are they necessary? What are the limits and challenges they face? How will science, technology and other human institutions color the advance of the datacenters, and will be colored by them? Studying possible answers to these questions and exploring possible future scenarios will help us see what lies around the corner from where we are today.

The challenges of networking, data storage, computing and power efficiency and effective user interface remain core to the design of data foundries. Other challenges which are much harder to comprehend and resolve have to do with the interaction of these new technologies with social and economic realities. Advances are required in a multitude of dimensions to produce next-generation datacenter systems and architectures..

ON-MOVE Workshop

Security and Privacy Considerations in Vehicular Communications for Smart Grid Applications

Dr. Kemal Akkaya

Associate Professor
Department of Electrical and Computer Engineering
Florida International University
Miami, Florida, USA

ABSTRACT

Plug-in Electric Vehicles (PEVs) have recently received increasing popularity to promote adoption of intermittent renewable energy sources by acting as energy storage systems. In this way, PEVs can inject power to the Smart Grid during periods of reduced production to balance demand. The US Department of Energy expects that about one million PEVs will be on the roads by the end of 2016. These PEVs will typically be equipped with wireless communication capabilities (e.g., DSRC or LTE) to coordinate charging and injection among themselves and the Smart Grid. Such communication, however, exposes information such as the PEVs' locations, their parking duration, the battery status, etc. which can be misused. Long-term analysis of schedule and location information may expose user's driving patterns and whereabouts that can be used by marketers. In addition, the coordinated charging system needs to securely bill the drivers for their payments which necessitates the design of secure protocols. This talk will first focus on the privacy and security aspects of vehicle-to-grid (V2G) and vehicle-to-vehicle (V2V) communications in general. In particular, privacy, authentication and confidentiality challenges will be discussed. We will then present a framework for privacy-preserving power injection protocol for the PEVs that sell power to the grid. The talk will conclude with the future issues in V2G and V2V communications.

Multi connectivity and energy efficiency in future 5G ultra dense deployment scenarios

Dr. Karl Andersson

Associate Professor
Pervasive and Mobile Computing
Luleå University of Technology, SWEDEN

ABSTRACT

In upcoming 5G networks, ultra dense deployment (UDN) is a scenario where the base stations are extremely dense in an area and enables extreme capacity per area ideally. Multi-connectivity is a way for connecting to several base stations at the same time both for performance and robustness reasons and enables to direct traffic to certain base stations and enable some sort of sleep mode for non used base stations. This enables energy efficiency in networks. The keynote addresses suitable smart energy efficiency algorithms that still enables robustness.

Practical Issues in Building Smart Home Applications

Professor Kamin Whitehouse

Commonwealth Associate Professor
Computer Science Department
University of Virginia
Charlottesville, Virginia, USA

ABSTRACT

Homes are rich with information about people’s health, energy consumption, and personal or family functions. This talk will discuss the practical challenges of deploying large-scale smart home applications. The talk will draw on experiences deploying over 2000 devices in over 60 homes and will highlight a phase transition where deployments become dramatically more difficult as they scale up in terms of 1) the number of nodes, 2) the length of time, and 3) the number of houses. The talk will distill these experiences down to a set of guidelines and design principles to help future deployments avoid the potential pitfalls of large-scale sensing in homes, and conclude with open questions and challenges that we still face today.

Carrots and Sticks - Incentives that Make Mobile Crowdsensing Work

Prof. Salil Kanhere

Associate Professor
School of Computer Science and Engineering
The University of New South Wales
Sydney, AUSTRALIA

ABSTRACT

Crowdsourcing offers a cost-effective approach to distributed problem solving and data collection by soliciting contributions (solutions, ideas, data, etc.) from a large group of people. Recently, due to the burgeoning smartphone industry and the surging demand for sensing data, a new mobile computing and sensing paradigm called mobile crowdsensing has emerged. It collects data through crowdsourcing and has created significant momentum in both industry and academia. Key to the viability of mobile crowdsensing is providing incentives to attain a sufficient level of user participation. This talk will present a primer on designing incentive mechanisms for ensuring successful crowdsourcing campaigns. In the first part, we take a socio-economic approach to connect participants into a social network via a relationship called endorsement, which is overlaid by economic incentives. The (dual) objective is to incentivize trustworthy crowdsensing. Next we focus on heterogeneous crowdsourcing, where not only the player types (abilities, costs) but also the beliefs about their respective types are different. We cast the problem as an asymmetric all-pay contest and use a series of reward functions to achieve optimal mechanism design. Finally, we propose to use Tullock contents as an alternative framework to design incentive mechanisms for crowdsourcing. We explore a new dimension of optimal Tullock contents design by provisioning the prize as a function.

WNM Workshop

Lessons Learned on Analyzing One-Way Network Traffic

Dr. Nur Zincir-Heywood

Professor
Computer Science
Dalhousie University
Halifax, Nova Scotia, CANADA

ABSTRACT

The rapid growth in size, and complexity of computer systems, and networks make network measurement and monitoring tasks increasingly important, and extremely challenging. The rate at which digital data is accumulated from such systems far exceeds the human ability to make sense of it, i.e., to interpret and attach meaning to it. Major challenges include data volume and diversity, data dependency, and system dynamics. The goal of this talk is to explore some of these challenges in the context of one-way traffic, while presenting research taken to mitigate the impact of these factors using (semi)automatic and intelligent systems.
