Linking Online Misuse-Resistant Authenticated Encryption and Blockwise Attack Models

Damian Vizár

Real-world applications of authenticated encryption often require the encryption to be computable online, e.g. to compute the ith block of ciphertext after having processed the first i blocks of plaintext. A significant line of research was dedicated to id ...

Authenticated Encryption with Variable Stretch

Serge Vaudenay, Damian Vizár, Reza Reyhanitabar

In conventional authenticated-encryption (AE) schemes, the ciphertext expansion, a.k.a.stretch or tag length, is a constant or a parameter of the scheme that must be fixed per key. However, using variable-length tags per key can be desirable in practice or ...

DES S-box generator

Serge Vaudenay, Lauren De Meyer

The Data Encryption Standard (DES) is a cryptographic algorithm, designed by IBM, that was selected to be the national standard in 1977 by the National Bureau of Standards. The algorithm itself was entirely published but the design criteria were kept secre ...

Open, privacy-preserving protocols for lawful surveillance

Bryan Alexander Ford

The question of how government agencies can acquire actionable, useful information about legitimate but unknown targets without intruding upon the electronic activity of innocent parties is extremely important. We address this question by providing experim ...

Subdomain and Access Pattern Privacy Trading off Confidentiality and Performance

Bin Lu, Thomas Locher, Matus Harvan

Homomorphic encryption and secure multi-party computation enable computations on encrypted data. However, both techniques suffer from a large performance overhead. While advances in algorithms might reduce the overhead, we show that achieving perfect (or e ...

Protecting Privacy through Distributed Computation in Multi-agent Decision Making

Boi Faltings, Thomas Léauté

As large-scale theft of data from corporate servers is becoming increasingly common, it becomes interesting to examine alternatives to the paradigm of centralizing sensitive data into large databases. Instead, one could use cryptography and distributed com ...

Privacy-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 ...

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 ...

A Related-Key Attack against Multiple Encryption based on Fixed Points

Serge Vaudenay, Atefeh Mashatan, Asli Bay

In order to alleviate the burden of short keys, encrypting a multiple times has been proposed. In the multiple encryption mode, there may be encryptions under the same or different keys. There have been several attacks against this encryption mode. When tr ...
