ePrint Report: Optimizing Attribute-based Encryption for Circuits using Compartmented Access Structures

Alexandru Ionita

Attribute-based encryption (ABE) is an asymmetric encryption method that allows expressive access granting mechanisms, with high applicability in modern IT infrastructure, such as Cloud or IoT systems. (Ezhilarasi et al., 2021; Touati and Challal, 2016) One open problem regarding ABE is using Boolean circuits as access structures. While Boolean Formulae were supported since the first ABE scheme proposed, there is still no efficient construction that supports Boolean …
