Graph induced multilinear maps from lattices
WebOct 30, 2024 · A systematic study of the GGH15 graded encoding scheme used with general branching programs, finding a candidate for witness encryption that exploits the fact that formulas in conjunctive normal form (CNFs) can be represented by general, read-once branching programs. 50 Highly Influenced PDF View 5 excerpts, cites results and … WebAn Alternative View of the Graph-Induced Multilinear Maps Yilei Chen February 29, 2016 Abstract In this paper, we view multilinear maps through the lens of “homomorphic obfuscation”. In specific, we show how to homomorphically obfuscate the kernel-test and affine subspace-test functionalities of high dimensional matrices.
