We propose an efficient revocable multi-authority large-universe attribute-based encryption
system deployed to cloud storage service, which supports multiple authorities issuing secret …

Data confidentiality and access control are the key technologies of secure Internet of things
(IoT) since the circulated application data on multiple different domains in IoT are generally …

Multi-authority attribute-based encryption (ABE) scheme can support the flexible fine-
grained sharing of encrypted data and solve a completely trust problem about a single …

For practical data sharing applications, many attributebased encryption (ABE) schemes
were proposed with different kinds of properties, such as supporting large universe …

We propose a new large-universe multi-authority ciphertext-policy attribute-based
encryption system. In this system, any string can be used as an attribute of the system, and …

Attribute based encryption scheme is widely used to share sensitive data in cloud storage
environment because it can realize fine-grained access control. Aiming at the problem of …

Attribute-based encryption (ABE) is a promising approach that enables scalable access
control on encrypted data. However, one of the main efficiency drawbacks of ABE is the lack …

Attribute-based encryption (ABE) is a promising cryptographic primitive achieving fine-
grained access control on encrypted data. However, efficient user revocation is always …

As a one-to-many public key encryption system, attribute-based encryption (ABE) enables
scalable access control over encrypted data in cloud storage services. However, efficient …

Attribute-based encryption (ABE) is a promising cryptographic primitive which can provide
fine-grained access control over encrypted data. Providing an efficient revocation …
