Unbounded Dynamic Predicate Compositions in ABE from Standard Assumptions
Nuttapong Attrapadung and Junichi Tomida
Abstract
At Eurocrypt'19, Attrapadung presented several transformations that dynamically compose a set of attribute-based encryption (ABE) schemes for simpler predicates into a new ABE scheme for more expressive predicates. Due to the powerful unbounded and modular nature of his compositions, many new ABE schemes can be obtained in a systematic manner. However, his approach heavily relies on
