Secure transmission using an untrusted relay with scaled compute-and-forward

Michael Christoph Gastpar, Jasper Goseling

A two-hop channel is considered, in which the source wants to send information to the destination while keeping the information confidential from the relay. A novel lattice chain and compute-and-forward based scheme is proposed in which the destination pro ...

Leakage-resilient non-malleable codes

Divesh Aggarwal

A recent trend in cryptography is to construct cryptosystems that are secure against physical attacks. Such attacks are usually divided into two classes: the \emph{leakage} attacks in which the adversary obtains some information about the internal state of ...

Secret Communication Over Broadcast Erasure Channels With State-Feedback

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

We consider a 1-to-K communication scenario, where a source transmits private messages to K receivers through a broadcast erasure channel, and the receivers feedback strictly, causally, and publicly their channel states after each transmission. We explore ...

Making Masking Security Proofs Concrete - Or How to Evaluate the Security of any Leaking Device

Alexandre Raphaël Duc, Sebastian Faust

We investigate the relationships between theoretical studies of leaking cryptographic devices and concrete security evaluations with standard side-channel attacks. Our contributions are in four parts. First, we connect the formal analysis of the masking co ...

Hiding Information in Multiple Level-line Moirés

Roger Hersch, Thomas Walger

Secure documents often comprise an information layer that is hard to reproduce. Moiré techniques for the prevention of counterfeiting rely on the superposition of an array of transparent lines or microlenses on top of a base layer containing hidden informa ...

Secure Communication in Erasure Networks with State-feedback

László Czap

The security and efficiency of communication are two of the main concerns for networks of today and the future. Our understanding of how to efficiently send information over various channels and networks has significantly increased in the past decade (see ...

Cyber-secure Communication Architecture for Active Power Distribution Networks

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Philippe Oechslin, Teklemariam Tsegay Tesfay

Active power distribution networks require sophisticated monitoring and control strategies for efficient energy management and automatic adaptive reconfiguration of the power infrastructure. Such requirements are realized by deploying a large number of var ...

Rebasing I/O for Scientific Computing: Leveraging Storage Class Memory in an IBM BlueGene/Q Supercomputer

Felix Schürmann, Pramod Shivaji Kumbhar, Miguel Angel Gila Arrondo, Davide Tacchella, Alessandro Curioni, Fabien Jonathan Delalondre, John Anthony Biddiscombe, Peter Morjan, Blake Fitch, Bernard Metzler, Lars Schneidenbach, Robert Germain

Storage class memory is receiving increasing attention for use in HPC systems for the acceleration of intensive IO operations. We report a particular instance using SLC FLASH memory integrated with an IBM BlueGene/Q supercomputer at scale (Blue Gene Active ...

Recommending software upgrades with Mojave

Willy Zwaenepoel, Ricardo Bianchini, Olivier Crameri

Software upgrades are frequent. Unfortunately, many of the upgrades either fail or misbehave. We argue that many of these failures can be avoided for users of the new version of the software by exploiting the characteristics of the upgrade and feedback fro ...

RFID seeking: Finding a lost tag rather than only detecting its missing

Chen Zhang, Qiang Wang, Jian Xu, Lei Xie

This paper proposes a novel type of RFID application, i.e., RFID seeking. Several existing types of RFID applications such as monitoring, searching, locating/navigating, are similar with RFID seeking. However, they are either inapplicable or vulnerable for ...
