Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn
as the foundation for secure cryptographic systems. Attractive features of lattice cryptography …

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 …

With the rapid development of the Internet of Things and cloud computing technologies,
smart health (s-health) is expected to significantly improve the quality of health care …

To achieve confidentiality, authentication, integrity of medical data, and support fine-grained
access control, we propose a secure electronic health record (EHR) system based on …

Data sharing becomes an exceptionally attractive service supplied by cloud computing
platforms because of its convenience and economy. As a potential technique for realizing …

The increasing volume of personal and sensitive data being harvested by data controllers
makes it increasingly necessary to use the cloud not just to store the data, but also to …

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 …

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) is a new vision for public key encryption that allows users
to encrypt and decrypt messages based on user attributes. For example, a user can create a …

We construct a simple fully homomorphic encryption scheme, using only elementary
modular arithmetic. We use Gentry's technique to construct a fully homomorphic scheme …
