WebAn open problem is to fix previous constructions to obtain a secure multilinear map. In this paper, we presented a variation of GGH15, which seems to thwart known attacks. 1.1 Our variation We describe a new multilinear map from lattices. Our variation follows same technique of GGH15 multilinear maps, but does not use directed acyclic graph.
