A Nonstandard Variant of Learning with Rounding with Polynomial Modulus and Unbounded Samples
Lattices LWE Learning with Rounding
2018/1/30
The learning with rounding problem (LWR) has become a popular cryptographic assumption to study recently due to its determinism and resistance to known quantum attacks. Unfortunately, LWR is only know...
Estimation of the Hardness of the Learning with Errors Problem with a Restricted Number of Samples
learning with errors hardness estimation lattice-based cryptography
2017/2/21
Lattice-based cryptography is a promising candidate to build cryptographic primitives that are secure against quantum algorithms. The Learning with Errors problem is one of the most important hardness...
Efficient Selection of Time Samples for Higher-Order DPA with Projection Pursuits
Higher-Order DPA Projection Pursuits
2016/1/9
The selection of points-of-interest in leakage traces is a frequently
neglected problem in the side-channel literature. However, it can
become the bottleneck of practical adversaries/evaluators as t...
Linear Cryptanalysis of PRINTcipher --- Trails and Samples Everywhere

2012/3/27
PRINTcipher is a recent lightweight block cipher designed by Knudsen et al. Some noteworthy characteristics are a burnt-in key, a key-dependent permutation layer and identical round keys. Independent ...
In addition to its usual complexity assumptions, cryptography silently as-
sumes that information can be physically protected in a single location. As we now
know, real-life devices are not ideal an...
