Flexible Attribute-Based Encryption
"... Abstract. In this paper, we propose a notion of flexible attribute-based encryption. Flexible attribute-based encryption is a variant of ciphertext-policy ABE, which allows one to loosen a decryption policy underlying a given ciphertext, if one knows some system-wide trapdoor information, without kn ..."

Attribute-based encryption for circuits
- In STOC
"... In an attribute-based encryption (ABE) scheme, a ciphertext is associated with an ℓ-bit public index ind and a message m, and a secret key is associated with a Boolean predicate P. The secret key allows to decrypt the ciphertext and learn m iff P (ind) = 1. Moreover, the scheme should be secure aga ..."

Distributed Attribute-Based Encryption
- in International Conference on Information Security and Cryptology (ICISC’08
, 2008
"... allows to encrypt data under an access policy, specified as a logical combination of attributes. Such ciphertexts can be decrypted by anyone with a set of attributes that fits the policy. In this paper, we introduce the concept of Distributed Attribute-Based Encryption (DABE), where an arbitrary num ..."

Decentralizing Attribute-Based Encryption
"... We propose a Multi-Authority Attribute-Based Encryption (ABE) system. In our system, any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters. A party can simply act as an ABE authority by creat ..."

Attribute-based Encryption with Break-glass
"... Abstract Attribute-based Encryption (ABE) allows for implementing fine-grained decentralized access control based on properties or attributes a user has. Thus, there is no need for writing detailed, user-based policies in advance. This makes ABE in particular interesting for implementing security me ..."

Verifiable Attribute Based Encryption
"... Abstract. In this paper, we construct two verifiable attribute-based encryption (VABE) schemes. One is with a single authority, and the other is with multi authorities. Not only our schemes are proved secure as the previous ABE schemes, they also provide a verification property. Adding the verificat ..."

Attribute-Based Encryption for Arithmetic Circuits
"... We present an Attribute Based Encryption system where access policies are expressed as polynomial size arithmetic circuits. We prove security against arbitrary collusions of users based on the learning with errors problem on integer lattices. The system has two additional useful properties: first, i ..."
