PEViD: privacy evaluation video dataset

Touradj Ebrahimi

Visual privacy protection, i.e., obfuscation of personal visual information in video surveillance is an important and increasingly popular research topic. However, while many datasets are available for testing performance of various video analytics, little ...

Cryptanalysis of the Double-Moduli Cryptosystem

Serge Vaudenay, Sonia Mihaela Bogos

In this article we present a lattice attack done on a NTRU-like scheme introduced by Verkhovsky in [1]. We show how, based on the relation between the public and private key, we can construct an attack which allows any passive adversary to decrypt the encr ...

Creating Shared Secrets out of Thin Air

Christina Fragouli, Suhas Diggavi, Iris Safaka

Current security systems typically rely on the adversary's computational limitations (e.g., the fact that it cannot invert a hash function or perform large-integer factorization). Wireless networks offer the opportunity for a different, complementary kind ...

1 Mbps coherent one-way QKD with dense wavelength division multiplexing and hardware key distillation

Andreas Peter Burg, Jeremy Hugues-Felix Constantin, Nicolas Gisin

We present the latest results obtained with a quantum cryptography prototype based on a coherent-one way quantum key distribution (QKD) scheme. To support its continuous high rate secret key generation we developed different low-noise single photon detecto ...

Resistance Against Iterated Attacks by Decorrelation Revisited

Serge Vaudenay, Atefeh Mashatan, Asli Bay

Iterated attacks are comprised of iterating adversaries who can make

d

plaintext queries, in each iteration to compute a bit, and are trying to distinguish between a random cipher

C

and the ideal random cipher

C^*

based on all bits. In EUROCRYPT '99, ...

Design and Analysis of Multi-Block-Length Hash Functions

Onur Özen

Cryptographic hash functions are used in many cryptographic applications, and the design of provably secure hash functions (relative to various security notions) is an active area of research. Most of the currently existing hash functions use the Merkle-Da ...

Privacy-Enhancing Technologies for Medical Tests Using Genomic Data

Jean-Pierre Hubaux, Erman Ayday, Jean Louis Raisaro

In this paper, we propose privacy-enhancing technologies for medical tests and personalized medicine methods, which utilize patients' genomic data. First, we highlight the potential privacy threats on genomic data and the challenges of providing privacy-pr ...
