WebSep 1, 2024 · We describe a cryptanalysis of the GGH15 multilinear maps. Our attack breaks the multipartite key-agreement protocol in polynomial time by generating an equivalent user private key; it also ... 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.

Only small plaintext elements s ∈ R are encoded.…” Section: Ggh15 Multilinear Maps mentioning confidence: 99% Cryptanalysis of GGH15 … 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- greenaway scott solicitors

WebMar 25, 2024 · In this talk I will first survey the cryptanalytic attacks on the candidate program obfuscators. I will then explain two attacks on the candidates obfuscators built on GGH15 multilinear maps, and mention two interesting open problems related to lattices and quantum algorithms.
