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. high fry leyton
