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.
