WebAug 26, 2016 · The GGH scheme, the first candidate of an (approximate) multilinear map, was recently found to be insecure by the Hu–Jia attack using low-level encodings of zero, but no polynomial-time attack was known without them.
WebIn this work, we describe a new graphinduced multilinear encoding scheme from lattices. In a graph-induced multilinear encoding scheme the arithmetic operations that are allowed are restricted through an explicitly defined directed graph (somewhat similar to the “asymmetric variant” of previous schemes). florida lipid institute winter parkWebthe multilinear map is de ned with respect to a directed acyclic graph.
