Webencoded value are associated with paths in the graph, and it is only possible to add encoding relative to the same paths, or to multiply encodings relative to “connected paths” (i.e., one ends where the other begins) Our candidate construction of graph-induced multilinear maps does not rely on ideal lattices or hard-to-factor integers. Webthe multilinear map is de ned with respect to a directed acyclic graph. Namely, encoded value are associated with paths in the graph, and it is only possible to add encoding relative to the same paths, or to multiply encodings relative to \connected paths" (i.e., one ends where the other begins) Our candidate construction of graph-induced ... dick building corp

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.
