Time and again, attribute-based encryption has been shown to be the natural cryptographic
tool for building various types of conditional access systems with far-reaching applications …

We propose a new generic framework for achieving fully secure attribute based encryption
(ABE) in prime-order bilinear groups. Previous generic frameworks by Wee (TCC'14) and …

We construct new functional encryption schemes that combine the access control
functionality of attribute-based encryption with the possibility of performing linear operations …

Decentralized multi-authority attribute-based encryption (MA-ABE) is a distributed
generalization of standard (ciphertext-policy) attribute-based encryption where there is no …

We present compact attribute-based encryption (ABE) schemes for NC^ 1 NC 1 that are
adaptively secure under the k-Lin assumption with polynomial security loss. Our KP-ABE …

We present new techniques for achieving strong attribute-hiding in prime-order bilinear
groups under the standard k-Linear assumption. Our main result is a “partially hiding” …

Attribute-based encryption (ABE) is a popular type of public-key encryption that enforces
access control cryptographically, and has spurred the proposal of many use cases. To …

We address the problem of ciphertext-policy attribute-based encryption with fine access
control, a cryptographic primitive which has many concrete application scenarios such as …

We present several transformations that combine a set of attribute-based encryption (ABE)
schemes for simpler predicates into a new ABE scheme for more expressive composed …

Abstract Wee (TCC'14) and Attrapadung (Eurocrypt'14) introduced predicate and pair
encodings, respectively, as a simple way to construct and analyze attribute-based …
