This paper presents the first generic black-box construction of registered attribute-based
encryption (Reg-ABE) via predicate encoding [TCC'14]. The generic scheme is based on k …

We construct the first decentralized multi-authority attribute-based encryption (MA-ABE)
scheme for a non-trivial class of access policies whose security is based (in the random …

Registered attribute-based encryption (Reg-ABE), introduced by Hohenberger et
al.(Eurocrypt'23), emerges as a pivotal extension of attribute-based encryption (ABE), aimed …

Attribute-based encryption (ABE) is an advanced cryptographic tool and useful to build
various types of access control systems. Toward the goal of making ABE more practical, we …

We present the first attribute-based encryption (ABE) scheme for deterministic finite
automaton (DFA) based on static assumptions in bilinear groups; this resolves an open …

A non-interactive zero-knowledge (NIZK) protocol enables a prover to convince a verifier of
the truth of a statement without leaking any other information by sending a single message …

We improve the first and the only existing prime-order fully adaptively secure decentralized
Multi-Authority Attribute-Based Encryption (MA-ABE) scheme for NC1 in Datta-Komargodski …

The celebrated work of Gorbunov, Vaikuntanathan and Wee GVW13 provided the first key
policy attribute based encryption scheme (ABE) for circuits from the Learning With Errors …

We present succinct and adaptively secure attribute-based encryption (ABE) schemes for
arithmetic branching programs, based on k-Lin in pairing groups. Our key-policy ABE …

We give an attribute-based encryption system for Turing Machines that is provably secure
assuming only the existence of identity-based encryption (IBE) for large identity spaces …
