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. WebAug 26, 2016 · The GGH scheme, the first candidate of an (approximate) multilinear map, was recently found to be insecure by the Hu–Jia attack using low-level encodings of zero, but no polynomial-time attack was known without them.

WebAbstract. We describe a cryptanalysis of the GGH15 multilinear maps. Our attack breaks the multipartite key-agreement protocol in polynomial time by generating an equivalent … 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 … Webresearches focus on algebraic security of obfuscation using the weak multilinear map models [4,19,29] to capture the currently known techniques to analyze obfuscations and multilinear map itself. Recently, GGH15 multilinear map has been in the spotlight because it is shown that GGH15 and its variants can be exploited to construct provable se- small 110 water pump
