WebA cryptographic -multilinear map is a kind of multilinear map, that is, a function such that for any integers and elements , , and which in addition is efficiently computable and satisfies some security properties. It has several applications on cryptography, as key exchange protocols, identity-based encryption, and broadcast encryption. 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. tax prep services naics
