Multi-dimensional Packing for HEAAN for Approximate Matrix Arithmetics
Homomorphic encryption approximate arithmetics matrix operations
2019/1/4
HEAAN is a homomorphic encryption (HE) scheme for approximate arithmetics. Its vector packing technique proved its potential in cryptographic applications requiring approximate computations, including...
A Bounded-Space Near-Optimal Key Enumeration Algorithm for Multi-Dimensional Side-Channel Attacks
cryptanalysis near-optimal ranks
2016/1/26
Enumeration of cryptographic keys in order of likelihood based on side-channel leakages has a significant importance in cryptanalysis. Previous algorithms enumerate the keys in optimal order, however ...
Predicate Encryption for Multi-Dimensional Range Queries from Lattices
public-key cryptography inner product
2016/1/5
We construct a lattice-based predicate encryption scheme for multi-dimensional range and multidimensional
subset queries. Our scheme is selectively secure and weakly attribute-hiding, and its securit...
Multi-Dimensional Montgomery Ladders for Elliptic Curves
multi-dimensional montgomery ladders elliptic curves
2008/12/2
Montgomery’s ladder algorithm for elliptic curve scalar multiplication uses only the xcoordinates
of points. Avoiding calculation of the y-coordinates saves time for certain curves.
Montgomery intro...
