Verifying Solutions to LWE with Implications for Concrete Security
lattices learning with errors discrete gaussian sampling
2019/6/21
A key step in Regev's (2009) reduction of the Discrete Gaussian Sampling (DGS) problem to that of solving the Learning With Errors (LWE) problem is a statistical test required for verifying possible s...

Cultural Heritage WebGIS WebGL Globe application Virtual Reality Virtual Heritage
2018/11/9
During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used...
LP Solutions of Vectorial Integer Subset Sums - Cryptanalysis of Galbraith's Binary Matrix LWE
Binary matrix LWE Linear Programming Cryptanalysis
2018/8/16
We consider Galbraith's space efficient LWE variant, where the (m×n)(m×n)-matrix AA is binary. In this binary case, solving a vectorial subset sum problem over the integers allows for decryption. We s...

Finding Small Solutions of the Equation $Bx-Ay=z$ and Its Applications to Cryptanalysis of the RSA Cryptosystem
RSA Cryptanalysis Lattice
2018/6/6
We present two attacks on RSA as its applications. One focuses on the case with known bits of the private exponent together with the prime factor, and the other considers the case with a small differe...
Improved Parallel Mask Refreshing Algorithms: Generic Solutions with Parametrized Non-Interference \& Automated Optimizations
Side-channel attacks masking countermeasure refreshing algorithms
2018/5/28
Refreshing algorithms are a critical ingredient for secure masking. They are instrumental in enabling sound composability properties for complex circuits, and their randomness requirements dominate th...
Supersingular isogeny graphs and endomorphism rings: reductions and solutions
post-quantum cryptography isogeny-based cryptography cryptanalysis
2018/4/26
In this paper, we study several related computational problems for supersingular elliptic curves, their isogeny graphs, and their endomorphism rings. We prove reductions between the problem of path fi...
Hashing solutions instead of generating problems: On the interactive certification of RSA moduli
RSA parameter validation zero-knowledge proofs
2018/1/12
Certain RSA-based protocols, for instance in the domain of group signatures, require a prover to convince a verifier that a set of RSA parameters is well-structured (e.g., that the modulus is the prod...
