Blockchain-based Practical Multi-agent Secure Comparison and its Application in Auctions

Boi Faltings, Sujit Prakash Gujar, Sankarshan Damle

AI applications find widespread use in a variety of domains. For further acceptance, mostly when multiple agents interact with the system, we must aim to preserve the privacy of participants information in such applications. Towards this, the Yao’s Million ...

Entering the plasma agriculture field: An attempt to standardize protocols for plasma treatment of seeds

Ivo Furno, Alan Howling, Fabio Avino, Alexandra Waskow

Plasma treatments are currently being assessed as a seed processing technology for agricultural purposes. There is sufficient information as a proof-of-concept, but a lack of standardization in the methodology prevents a convincing evaluation of plasma tre ...

Orientation invariant and non-parametric Axon Diameter Distribution mapping using PGSE and regularized discrete linear modeling

Jean-Philippe Thiran, David Paul Roger Romascano, Alessandro Daducci, Muhamed Barakovic, Anna Auria Rasclosa, Tim Bjørn Dyrby

Axon Diameter Distributions (ADDs) change during brain development and are altered in several brain pathologies. Mapping ADDs non-invasively using dMRI could provide a useful biomarker, but existing methods are either parametric, orientation dependent, sur ...

On Modeling Terrorist Frauds

Serge Vaudenay

Quite recently, distance-bounding protocols received a lot of attention as they offer a good solution to thwart relay attacks. Their security models at still unstable, especially when considering terrorist fraud. This considers the case where a malicious p ...

Speculative Linearizability

Rachid Guerraoui, Viktor Kuncak, Giuliano Losa

Linearizability is a key design methodology for reasoning about implementations of concurrent abstract data types in both shared memory and message passing systems. It provides the illusion that operations execute sequentially and fault-free, despite the a ...

A Provably Starvation-Free Distributed Directory Protocol

Vincent Gramoli, Hagit Albo Attiya

This paper presents Combine, a distributed directory protocol for shared objects, designed for large-scale distributed systems. Directory protocols support move requests, allowing to write the object locally, as well as lookup requests, providing a read-on ...

Smashing SQUASH-0

Serge Vaudenay, Khaled Ouafi

At the RFID Security Workshop 2007, Adi Shamir presented a new challenge-response protocol well suited for RFIDs, although based on the Rabin public-key cryptosystem. This protocol, which we call SQUASH-0, was using a linear mixing function which was subse ...

Cryptanalysis of e-mail protocols providing perfect forward secrecy

Recently, two e-mail protocols were proposed claiming to provide perfect secrecy. These protocols use authentication and (Diffie-Hellman) key-exchange techniques, and as such, other standard security criteria besides perfect forward secrecy include key-rep ...

Tackling Acceptability Issues in Communities of Practice by Providing a Lightweight Email-based Interface to eLogbook: a Web 2.0 Collaborative Activity and Asset Management System

Denis Gillet, Christophe Salzmann

eLogbook is a Web-based collaborative environment designed for communities of practice. It enables users to manage joint activities, share related assets and get contextual awareness. In addition to the original Web- based access, an email-based eLogbook i ...

Generic emergent overlays in arbitrary peer identifier spaces

Karl Aberer, Wojciech Galuba

Unstructured overlay networks are driven by simple protocols that are easy to analyze and implement. The lack of structure, however, leads to weak message delivery guarantees and poor scaling. Structured overlays impose a global overlay topology that is th ...

DOMINO: Detecting MAC layer greedy behavior in IEEE 802.11 hotspots

Jean-Pierre Hubaux, Alaeddine El Fawal, Imad Aad, Maxime Raya

IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter ...

Mobility Helps Peer-to-Peer Security

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...

Enforcing email addresses privacy using tokens

Serge Vaudenay, Roman Schlegel

We propose a system which allows users to monitor how their email addresses are used and how they spread over the Internet. This protects the privacy of the user and can reduce the spam phenomenon. Our solution does not require changes to the email infrast ...
