Title:
Ideal Multilinear Maps Based on Ideal Lattices
Authors: Gu Chunsheng
Abstract:Cryptographic multilinear maps have many applications, such as multipartite key exchange and software obfuscation. However, the encodings of three current constructions are “noisy” and their multilinearity levels are fixed and bounded in advance. In this paper, we describe a candidate construction of ideal multilinear maps by using ideal lattices, which supports arbitrary multilinearity levels. The security of our construction depends on new hardness assumptions.
