A Collaborative Key Management Protocol in Ciphertext Policy Attribute-Based Encryption for Cloud Data Sharing

IEEE Access, 2017
Ciphertext policy attribute-based encryption (CP-ABE) is a promising cryptographic technique for fine-grained access control of outsourced data in the cloud. However, some drawbacks of key management hinder the popularity of its application. One drawback

Role of Mid‐ and High‐Latitude, Southern Hemisphere Processes for Ushering in the Middle Pleistocene Transition

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Glacial‐interglacial cycles increased in length from about 41 to 100 thousand years during the Middle Pleistocene Transition (MPT) about 1.5 to 0.8 million years ago. This took place in step with strong global cooling after several million years of weaker cooling.

Fully Secure Cipertext-Policy Hiding CP-ABE

, 2011
In ciphertext-policy attributed-based encryption (CP-ABE), each ciphertext is labeled by the encryptor with an access structure (also called ciphertext policy) and each private key is associated with a set of attributes. A user should be able to decrypt a ciphertext if and only if his private key attributes satisfy the access structure.

A Lightweight Policy Preserving EHR Sharing Scheme in the Cloud

IEEE Access, 2018
Electronic Health Record (EHR) is a digital health documentary. It contains not only the health-related records but also the personal sensitive information. Therefore, how to reliably share EHR through the cloud is a challenging issue.

Constant Size Ciphertext Distributed CP-ABE Scheme With Privacy Protection and Fully Hiding Access Structure

IEEE Access, 2019
In ciphertext-policy attribute-based encryption (CP-ABE) schemes, the computational overhead and the length for the ciphertext are positively correlated with the complexity of the access structure. In addition, the access structure embedded in ciphertext
