Webing a multilinear map in 2013. Starting from this work, many subsequent studies have proposed plausible constructions of iO upon candidate multilinear maps [1{3,6,17,18,24{27,30,31,35]. However, all of the current constructions of multilinear map, essentially classi ed as GGH13, CLT13 and GGH15 [15,16,19], are merely candidates. Webants [7,8,10,22,35]. Therefore, the GGH15 multilinear map has been believed to be the most plausible candidate for constructing the general-purpose obfus-cation. In this … phil jefferys
