Identity-Based Key-Encapsulation Mechanism from Multilinear Maps
Hao Wang, Lei Wu, Zhihua Zheng, and Yilei Wang
Abstract
We construct an Identity-Based Key Encapsulation Mechanism (IB-KEM) in a generic "leveled" multilinear map setting and prove its security under multilinear decisional Diffie-Hellmanin assumption in the selective-ID model. Then, we make our IB-KEM translated to the GGH framework, which defined an "approximate" version of a multilinear group family from ideal lattices, and modify our proof of security to use the GGH graded algebras analogue of multilinear maps.
