In traditional cloud storage systems, attribute-based encryption (ABE) is regarded as an
important technology for solving the problem of data privacy and fine-grained access control …

Cloud computing enables enterprises and individuals to outsource and share their data.
This way, cloud computing eliminates the heavy workload of local information infrastructure …

To manage outsourced encrypted data sharing in clouds, attribute-based proxy re-
encryption (ABPRE) has become an elegant primitive. In ABPRE, a cloud server can …

随着云计算技术的日益普及, 公共云存储服务已经得到普遍的应用, DropBox, Google Drive,

(57) ABSTRACT A system and method for communicating information between a first party
and a second party, comprising the steps of receiving, by an intermediary, an identifier of …

In several distributed systems a user should only be able to access data if a user posses a
certain set of credentials or attributes. Currently, the only method for enforcing such policies …

Although many users outsource their various data to clouds, data security and privacy
concerns are still the biggest obstacles that hamper the widespread adoption of cloud …

Attributes define, classify, or annotate the datum to which they are assigned. However,
traditional attribute architectures and cryptosystems are ill-equipped to provide security in …

We propose attribute-based encryption schemes where encryptor-specified access
structures (also called ciphertext policies) are hidden. By using our schemes, an encryptor …

Cloud computing is a revolutionary computing paradigm, which enables flexible, on-
demand, and low-cost usage of computing resources, but the data is outsourced to some …
