Graph-induced multilinear maps from lattices
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). WebBuilding upon the GGH13 construction, Coron, Lepoint, and Tibouchi (2013) (CLT13) presented an alternate construction of multilinear maps over the integers. Recently, …

WebAn Alternative View of the Graph-Induced Multilinear Maps Yilei Chen February 29, 2016 Abstract In this paper, we view multilinear maps through the lens of “homomorphic obfuscation”. In specific, we show how to homomorphically obfuscate the kernel-test and affine subspace-test functionalities of high dimensional matrices.
