Palestra 1A (P1A): Energy Efficient Security for IoT Devices

David Ott (Intel Labs)

Abstract: Power constraints in IoT devices follow from their reliance on finite lifetime batteries which, when depleted, will terminate the device's operation. Computational requirements for IoT devices have increased sharply over time as the amount of data collected, processed, and communicated has increased. Meanwhile, capacity gains in battery technology have increased only incrementally over the years. The result is the well-known battery gap. As security solutions (e.g., data encryption) similarly increase IoT computational requirements over time in order to remain robust against increasingly capable attackers, an associated security processing gap exists. In this talk, I will describe the Intel-Brazil research collaboration on Energy Efficient Security for IoT Devices, including research objectives, energy measurement methodologies, and some sample research results. Included also will be a few reflections on industry-academia collaboration in researching security solutions for the future of technology.

Palestra 1B (P1B): Future IoT Security Challenges

Rafael Misoczki (Intel Labs)

Abstract: Internet-of-Things is a fascinating topic. It combines all sorts of devices, with different computational power, network bandwidth/speed and energy resources, in a collaborative fashion to achieve an ultimate goal. Due to this discrepancy in terms of resources (from very scarce up to very empowered), providing a concise and efficient security strategy across an IoT vertical is, and has always been, a challenge. If this situation is already challenging now, think about future IoT applications where the scale of the solutions will be exponentially larger and the interdependency between security and safety might turn a simple security vulnerability into a real life-threatening situation. In this short talk, I plan to discuss about a few future IoT applications, such as automotive, smart cities, healthcare and home automation, and their intrinsically related security research challenges.

Palestra 2 (P2): Distributed Differential Privacy

Christopher Clifton (Purdue University, EUA)

Abstract: Information Security has long been based on cryptography-style all-or-nothing definitions, such as ciphertext indistinguishability as a measure of confidentiality. This is often inappropriate in a data privacy context; people want their data to be used, but in a controlled, limited manner. This talk will describe differential privacy as a means for balancing data use and confidentiality. We will then show how this solves problems that are swept under the rug in traditional confidentiality definitions.
This will be presented in the context of a distributed data scenario: attempting to share data analysis without sharing the underlying data. Neither secure multiparty computation or differential privacy adequately solves this problem on its own, but combined, we can achieve good results while controlling disclosure of individual data. Efficiently combining these techniques turns out to be non-trivial, we will show some of the challenges and how they can be solved.

Short bio: Dr. Clifton is a Professor of Computer Science at Purdue University. He works on data privacy, particularly with respect to analysis of private data.

Before joining MITRE in 1995, he was an assistant professor of computer science at Northwestern University. He has a Bachelor's and Master's degree (1986) from the Massachusetts Institute of Technology, and a Ph.D. (1991) from Princeton University.

Palestra 3 (P3): IoT Blockchain: Open, Secure, Private and Trusted Internet of Things Stack

Martín Serrano (Insight Centre for Data Analytics, NUI Galway, IRL)

Abstract: Today people have a greater awareness about the benefits of Internet of Things sensed-enabled services, likewise more sensing services are easier to adopt and deploy. Cities are a clear example where IoT has influenced big changes for its infrastructure and its inhabitants, for example today there are cities technologically equipped and socially organized in a way that the generation and deployment of better citizen services and solutions are more rapidly adopted (e.g. Smart Cities). The Internet of Things is already considered the scientific evolution of the Internet that comes with a technology deployment wave of connected devices.
The Open Internet of Things stack, published at the IEEE IoT newsletter in 2015, has been designed in the context of having IoT systems and cloud infrastructures. It is the methodology that defines and establishes the relations between the operations and the role that "things" can play in the whole IoT system(s), likewise it represents the functionality or services that applications are able to provide and support. However the big concern is how Open and Trusted is the Internet of Things Infrastructure and how reliable are the services running in IoT infrastructure to offer data privacy and access security based on IoT services transactions.
In this talk we will go through todays' Open, Security, Privacy and Tryst relations and how the IoT technology and the global conditions, according with new data trends are the channels for user acceptance and large deployments in global user communities. The recently introduced, distributed blockchain, in the security market draws IoT directions to discuss and identify how IoT must be designed to be secure, transparent, highly resistant to outages, auditable, and efficient. The emergent technologies like blockchain will demonstrate where technology has evolved and the manufacturing cost being reduced or not.

Palestra 4 (P4): The Cyberspace Battle for Information: Combating Internet Censorship

Amir Houmansadr (University of Massachusetts Amherst, EUA)

Abstract: The Internet has become ubiquitous, bringing many benefits to people across the globe. Unfortunately, Internet users face threats to their security and privacy: repressive regimes deprive them of freedom of speech and open access to information, governments and corporations monitor their online behavior, advertisers collect and sell their private data, and cybercriminals hurt them financially through security breaches. My research aims to make Internet communications more secure and privacy-preserving. In this talk, I will focus on the design, implementation, and analysis of tools that help users bypass Internet censorship. I will discuss the major challenges in building robust censorship circumvention tools, introduce two novel classes of systems that we have developed to overcome these challenges, and conclude with several directions for future research.
