Tweakable Block Ciphers
We propose a new cryptographic primitive, the “tweakable block cipher.” Such a cipher has not only the usual inputs—message and cryptographic key—but also a third input, th...

On the Security of Oscillator-Based Random Number Generators
Physical random number generators (a.k.a. TRNGs) appear to be critical components of many cryptographic systems. Yet, such building blocks are still too seldom provided with a form...

Short Undeniable Signatures Based on Group Homomorphisms
This paper is devoted to the design and analysis of short undeniable signatures based on a random oracle. Exploiting their online property, we can achieve signatures with a fully s...

Mutual Information Analysis: a Comprehensive Study
Mutual Information Analysis is a generic side-channel distinguisher that has been introduced at CHES 2008. It aims to allow successful attacks requiring minimum assumptions and kno...

Universally Composable Symbolic Security Analysis
In light of the growing complexity of cryptographic protocols and applications, it becomes highly desirable to mechanize — and eventually automate — the security analysis of p...

Wildcarded Identity-Based Encryption
In this paper we introduce a new primitive called identity-based encryption with wildcards, or WIBE for short. It allows a sender to encrypt messages to a whole range of receivers ...

An L(1/3) Discrete Logarithm Algorithm for Low Degree Curves
We present an algorithm for solving the discrete logarithm problem in Jacobians of families of plane curves whose degrees in X and Y are low with respect to their genera. The fin...
