The next CITI talk will take place on 26th May at 11 am in Amphi Chappe. This seminar entitled “A new approach for secure personal cloud” will be presented by Nicolas Anciaux, researcher at INRIA, in the SMIS project.

Abstract

In the current Web model, individuals delegate the management of their data to online applications, each storing and exploiting the data into their own Web data silo. No concrete guarantee is offered to the individual regarding the usage and dissemination of their personal information, which often lack of transparency and depend on the underlying business models.
Today, a large economical and political consensus emerges to reestablish the control of the individuals on their data and improve trust. The current centralized approach seems by essence incapable of closing the gap. The SMIS team addresses this issue through the paradigm of “Personal Data Stores”, where individuals manage their digital life from a secure and personal hardware platform. Our research focus on several important prerequisites. In particular, we design embedded data management techniques for tamper resistant components, we work on Privacy-by-Design architectures based on an ecosystem of smart objects, and we study privacy preserving data dissemination models and distributed computations for such architectures. The presentation will present architectural considerations, embedded data management techniques, and application examples, that we consider emblematic in this work.

Bio

Nicolas Anciaux is a researcher at INRIA, in the SMIS project which focuses on secured and mobile information systems. He received his PhD in 2004 and his French Habilitation in 2014 from University of Versailles. Before joining Inria, Nicolas was a post-doc researcher at University of Twente and studied database implementations of the “right-to-be-forgotten” in ambient intelligent environments. Since he joined INRIA in 2006, his research interests lie in the area of data management on specific hardware architecture, and more precisely on secure chips and embedded systems. He proposes architectures using secure hardware, and data structures and algorithms to manage personal data with strong privacy guarantees using tamper resistant hradware. He is a co-designer of PlugDB, a secure and personal database device. Since 2015, Nicolas co-animates the research activities of the privacy cluster of the Digital Society Institute which brings together economists, jurists and computer scientists.

The next CITI talk will take place on the 29th of April at 11 am. This talk entitled “Visible Light Communication for the Internet-of-Things” will be presented by Stefan Mangold, founder of Lovefield Wireless (Switzerland) and associate professor with ETH Zurich.

Abstract

Visible Light Communication (VLC) with Light Emitting Diodes (LEDs) as transmitters and receivers enables low bitrate wireless adhoc networking, which is an interesting approach for consumer electronics such as toys and related applications in the entertainment industry. LED-to-LED VLC networks with VLC devices communicating over free-space optical links achieve a throughput of a few kilobit per second at distances of up to ten meters. LED-to-LED VLC networks are useful for combining light bulbs and illumination with low-complex networking. In this talk, we present recent research achievements in this field, address open challenges, and demonstrate the performance of a software-based VLC physical layer and a VLC medium access control layer that retain the simplicity of the LED-to-LED approach.

Abstract:

Since 2000, Fing “has been exploring the transforming potential of technologies, when placed in the hands of millions of people”. How to characterise this transforming potential, at a time when everybody talks about “digital transition” (and therefore a systemic change presented as both ineluctable and the “blues of the Net”)? What if “the digital era” was a pretext to allow oneself to think differently on any topic?
Based on some of Fing current works, we will look at how those works have open new ways, and the possible interactions with questions asked by the Inria researchers (and others):
– Personal data and privacy: what about focusing not only on the protection of individuals but also on their capacitation, by putting them in the position to be able to produce, capture and use their personal data for themselves?
– Ecological transition and digital transition: what if digital was the way to green transition, and ecology the collective aim missing from digital transition?
– Work: what if digital transition became an asset to bring meaning to work and professional itineraries?

Daniel Kaplan, 53, is the founder and CEO of the Next-Generation Internet Foundation (FING), a nonprofit Think-&-Do-Tank that produces and shares novel and actionable ideas to anticipate digital transformations.
In 1986, he cofounded one of the world’s first digital communication agencies, JKLM, which he headed until the early 1990s. He then became a consultant and co-founded Proposition, a consultancy specialized in digital strategies.
Since the 1990’s, Daniel Kaplan has been deeply involved in the Internet’s development and evolution. He was VP-Membership of the Internet Society worldwide, and contributed to the creation of ICANN. He served in the European Commission’s e-Europe’s Experts Chamber and currently sits in France’s National Digital Council.
He is a member of several large companies’ and research centre’s Foresight Committees.
Mr. Kaplan has written or directed more than 25 books and public reports on the internet, mobility and ubiquitous networking, ambient intelligence, e-inclusion, e-commerce, e-education, electronic media, cities and sustainable development, privacy and digital identities…

This presentation will focus on the emerging transmission technologies dedicated to IoT networks. We first point out the need of dedicated technologies for IoT. Then, we present the PHY and MAC layers of the technologies that are already deployed, or likely to be deployed: UNB by SigFox, CSS by LoRaTM, Weighless, and RPMA by Ingenu. We then compare their performances to highlight their pros and cons.

Abstract:

Primary user emulation attacks (PUEAs) are one of the most damaging threats in cognitive radio networks. Malicious or selfish secondary users pretend legitimate primary users to profit from the opportunistic use of the licensed frequency spectrum. Since cognitive radio importance has enhanced as an approach to spectral efficiency and to diminish the negative effects of wireless network scalability, approaches for PUEAs defense have arisen, evolving their architectural strategy, node’s operation and analysis design. This talk overviews recent achievement in PUEA defenses and presents a classification. Persistently unsolved challenges in the field are highlighted, and a framework for tackling one of the main challenges – the lack of flexibility to address this highly compromising attack – is outlined, promoting progress in the art of PUEA defense. As proof of concept, results present improvements in attack analysis employing flexible and multidimensional techniques on a case study. Finally, open issues and future directions are emphasized.
