Fast, Compact, and Expressive Attribute-Based Encryption
attribute-based encryption standard assumption non-monotone
2019/8/27
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 propose key-policy (KP)...
ABFKS: Attribute-Based Encryption with Functional Keyword Search in Fog Computing
Attribute-based encryption Keyword search Fog computing
2019/8/2
We provide a new frame in this paper, the ciphertext-policy attribute-based encryption with functional keyword search (ABFKS) in fog computing. The ABFKS achieves functional keyword search and peer-pe...
Modern Family: A Revocable Hybrid Encryption Scheme Based on Attribute-Based Encryption, Symmetric Searchable Encryption and SGX
Cloud Security Storage Protection Access Control, Policies
2019/6/12
Secure cloud storage is considered as one of the most important issues that both businesses and end-users take into account before moving their private data to the cloud. Lately, we have seen some int...
Attribute Based Encryption for Deterministic Finite Automata from DLIN
Attribute-based encryption deterministic finite automata decisional linear assumption
2019/6/5
Waters [Crypto, 2012] provided the first attribute based encryption scheme ABE for Deterministic Finite Automata (DFA) from a parametrized or ``q-type'' assumption over bilinear maps. Obtaining a cons...
Attribute Based Encryption (and more) for Nondeterministic Finite Automata from LWE
Non-determinisitic Finite Automata Attribute based Encrytion Predicate Encryption
2019/6/4
Constructing Attribute Based Encryption (ABE) [SW05] for uniform models of computation from standard assumptions, is an important problem, about which very little is known. The only known ABE schemes ...
Fully Secure Attribute-Based Encryption for $t$-CNF from LWE
attribute-based encryption ABE ciphertext policy
2019/4/10
Attribute-based Encryption (ABE), first introduced by [SW05,GPSW06], is a public key encryption system that can support multiple users with varying decryption permissions. One of the main properties o...
Multi-Authority Attribute-Based Encryption from LWE in the OT Model
attribute-based encryption LWE
2019/3/13
In a (ciphertext policy) attribute-based encryption (ABE) scheme, a ciphertext is associated with a predicate ϕϕ and a secret key is associated with a string xx such that a key decrypts a ci...
Unbounded Dynamic Predicate Compositions in Attribute-Based Encryption
attribute-based encryption predicate encryption nested policy
2019/3/4
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 predicates. Previous proposa...
The Lord of the Shares: Combining Attribute-Based Encryption and Searchable Encryption for Flexible Data Sharing
Cloud Security Storage Protection Access Control
2018/12/19
Secure cloud storage is considered one of the most important issues that both businesses and end-users are considering before moving their private data to the cloud. Lately, we have seen some interest...
A fully distributed revocable ciphertext-policy hierarchical attribute-based encryption without pairing
Cloud computing Hierarchical attribute-based encryption Access control
2018/11/20
Several appealing features of cloud computing such as cost-effectiveness and user-friendliness have made many users and enterprises interested to outsource their sensitive data for sharing via cloud. ...
Realizing Chosen Ciphertext Security Generically in Attribute-Based Encryption and Predicate Encryption
Attribute-Based Encryption Predicate Encryption
2018/11/16
We provide generic and black box transformations from any chosen plaintext secure Attribute-Based Encryption (ABE) or One-sided Predicate Encryption system into a chosen ciphertext secure system. Our ...
On Enabling Attribute-Based Encryption to Be Traceable against Traitors
Attribute-Based Encryption Traitor Tracing Framework
2018/11/6
Attribute-Based Encryption (ABE) is a versatile one-to-many encryption primitive which enables fine-grained access control over encrypted data. Due to its promising applications in practice, ABE has b...
Decentralized Policy-Hiding Attribute-Based Encryption with Receiver Privacy
public-key cryptography attribute-based encryption
2018/8/21
Attribute-based encryption (ABE) enables limiting access to encrypted data to users with certain attributes. Different aspects of ABE were studied, such as the multi-authority setting (MA-ABE), and po...
Mitigating the One-Use Restriction in Attribute-Based Encryption
attribute-based encryption one-use restriction
2018/7/9
We present a key-policy attribute-based encryption scheme that is adaptively secure under a static assumption and is not directly affected by an attribute "one-use restriction." Our construction impro...
Time-Based Direct Revocable Ciphertext-Policy Attribute-Based Encryption with Short Revocation List
public-key cryptography Revocable Attribute-Based Encryption
2018/4/11
In this paper, we propose an efficient revocable Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme. We base on the direct revocation approach, by embedding the revocation list into cipherte...
