Dual System Groups and its Applications --- Compact HIBE and More
Jie Chen and Hoeteck Wee
Abstract
We introduce the notion of *dual system groups*.
- We show how to derive compact HIBE by instantiating the dual system framework in Waters (Crypto '09) and Lewko and Waters (TCC '10) with dual system groups. Our construction provides a unified treatment of the prior compact HIBE schemes from static assumptions.
- We show how to instantiate dual system groups under the decisional subgroup assumption in composite-order groups and the decisional linear assumption (
