Attribute-based encryption (ABE) for cloud computing access control is reviewed in this
article. A taxonomy and comprehensive assessment criteria of ABE are first proposed. In the …

Recently, using advanced cryptographic techniques to process, store, and share data
securely in an untrusted cloud environment has drawn widespread attention from academic …

Abstract 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 …

Attribute based encryption (ABE)[13] determines decryption ability based on a user's
attributes. In a multi-authority ABE scheme, multiple attribute-authorities monitor different …

Attribute-based encryption (ABE) can guarantee confidentiality and achieve fine-grained
data access control in a cloud storage system. Due to the fact that every attribute in ABE may …

Data access control is an effective way to ensure data security in the cloud. However, due to
data outsourcing and untrusted cloud servers, the data access control becomes a …

Now more and more data are being outsourced to cloud services. In order to ensure data
security and privacy, data are usually stored on the cloud server in the form of ciphertext …

Attribute-based encryption (ABE) generalizes public-key encryption and enables fine-
grained control to encrypted data. However, ABE upends the traditional trust model of public …

We propose a new decentralized access control scheme for secure data storage in clouds
that supports anonymous authentication. In the proposed scheme, the cloud verifies the …

Online social networks (OSNs) are immensely popular, with some claiming over 200 million
users. Users share private content, such as personal information or photographs, using OSN …
