Graph-induced multilinear maps from lattices

WebThe construction combines the graph-induced multilinear maps by Gentry, Gorbunov and Halevi [GGH15], their candidate obfuscator, and the lattice-based PRFs of [BPR12,BLMR13]. At the heart of our technical contribution is identifying a restricted (yet still powerful) variant of the GGH15 maps, whose security can be reduced to LWE. WebMultilinear Maps (MMAPs) A very powerful crypto tool. Enables computation on “hidden data” Similar to homomorphic encryption (HE) But HE is too “all or nothing” No key: …
