Multilinear Map via Scale-Invariant FHE: Enhancing Security and Efficiency
Jinsu Kim, Sungwook Kim, and Jae Hong Seo
Abstract
Cryptographic multilinear map is a useful tool for constructing numerous secure protocols and Graded Encoding System (GES) is an {\em approximate} concept of multilinear map. In multilinear map context, there are several important issues, mainly about security and efficiency. All early stage candidate multilinear maps are recently broken by so-called zeroizing attack, so that it is highly required to develop reliable mechanisms to prevent zeroizing attacks. Moreover, the encoding size in all candidate multilinear maps grows quadratically in terms of multilinearity parameter
