Triangle Network Secrecy
Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran
We characterize the secret message capacity of the triangle network, that consists of a source, a relay and a destination connected through orthogonal erasure channels. A passive eavesdropper, Eve, wiretaps any one of the three channels. The source and the ...
Ieee2014Analyzing and comparing the AES architectures for their power consumption
It has been a decade since the block cipher Rijndael-with some minor changes-takes the name AES (Advanced Encryption Standard) and becomes the new block cipher standard of US government. Over the passed years, through deeper analysis and conducted measurem ...
Springer2014Automated Side-Channel Vulnerability Discovery and Hardening
In traditional cryptography, an attacker tries to infer a mathematical relationship between the inputs and outputs of a cryptosystem to recover secret information. With the advances in the theoretical basis of the cryptographic algorithms, this task became ...
EPFL2014Efficient Non-malleable Codes and Key-Derivation for Poly-size Tampering Circuits
Non-malleable codes, defined by Dziembowski, Pietrzak and Wichs (ICS ’10), provide roughly the following guarantee: if a codeword c encoding some message x is tampered to c' = f(c) such that c c, then the tampered message x contained in c reveals no inf ...
Springer2014OMD: A Compression Function Mode of Operation for Authenticated Encryption
Serge Vaudenay, Damian Vizár, Reza Reyhanitabar
We propose the Offset Merkle-Damgård (OMD) scheme, a mode of operation to use a compression function for building a nonce-based authenticated encryption with associated data. In OMD, the parts responsible for privacy and authenticity are tightly coupled to ...
Springer International Publishing2014TCHo: A Code-Based Cryptosystem
Serge Vaudenay, Alexandre Raphaël Duc
TCHo is a public-key cryptosystem based on the hardness of finding a multiple polynomial with low weight and on the hardness of distinguishing between the output of an LFSR with noise and some random source. An early version was proposed in 2006 by Finiasz ...
Springer Berlin Heidelberg2013Privacy-Enhancing Technologies for Medical Tests Using Genomic Data
Jean-Pierre Hubaux, Erman Ayday, Jean Louis Raisaro
We propose privacy-enhancing technologies for medical tests and personalized medicine methods, which utilize patients’ genomic data. Focusing specifically on a typical disease-susceptibility test, we develop a new architecture (between the patient and the ...
2013Permutation-based Sequential Pattern Hiding
Sequence data are increasingly shared to enable mining applications, in various domains such as marketing, telecommunications, and healthcare. This, however, may expose sensitive sequential patterns, which lead to intrusive inferences about individuals or ...
Ieee2013Privacy-Preserving Processing of Raw Genomic Data
Jean-Pierre Hubaux, Erman Ayday, Jean Louis Raisaro, Adam Molyneaux, Urs Beda Hengartner
Geneticists prefer to store patients' aligned, raw genomic data, in addition to their variant calls (compact and summarized form of the raw data), mainly because of the immaturity of bioinformatic algorithms and sequencing platforms. Thus, we propose a pri ...
