Attribute-Based Symmetric Searchable Encryption

2020
Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data while preserving the privacy of both the files and the queries. Unfortunately, majority of the SSE schemes allows users to either decrypt the whole ciphertext or nothing at all.

On Anonymous Attribute Based Encryption

2015
Attribute Based Encryption ABE has found enormous scope in data confidentiality and fine-grained access control of shared data stored in public cloud. Classical ABE schemes require attaching the access policy along with the ciphertext, where the access policy describes required attribute values of a receiver.

Dual-Policy Attribute Based Encryption

2009
We present a new variant of Attribute based encryption (ABE) called Dual-Policy ABE. Basically, it is a conjunctively combined scheme between Key-Policy and Ciphertext-Policy ABE, the two previous available types of ABE. Dual-Policy ABE allows simultaneously two access control mechanisms over encrypted data: one involves policies over objective ...

Attribute-based encryption with encryption and decryption outsourcing

2014
In this paper we propose a new scheme for ciphertext-policy attribute-based encryption that allows outsourcing of computationally expensive encryption and decryption steps. The scheme constitutes an important building block for mobile applications where both the host and users use mobile devices with limited computational power. In the proposed scheme,

Key Cooperative Attribute-Based Encryption

Attribute-based encryption (ABE) is an important technology in building access control systems with precise control and scalability. In an ABE system, there exists a private key generator (PKG) that issues all private keys. The PKG has a significant drawback referred to as the huge key management burden in large-scale user systems.

Outsourcing Encryption of Attribute-Based Encryption with MapReduce

2012
Attribute-based encryption (ABE) is a promising cryptographic tool for fine-grained access control. However, the computational cost in encryption commonly grows with the complexity of access policy in existing ABE schemes, which becomes a bottleneck limiting its application.

Attribute-Based Broadcast Encryption Scheme Made Efficient

2008
In this paper, we describe a new broadcast encryption scheme for stateless receivers. The main difference between our scheme and the classical ones derived from the complete subtree paradigm is that the group of privileged users is described by attributes.
