An Improved Ciphertext-Policy Attribute-Based Encryption Scheme in Power Cloud Access Control
Applied Sciences, 2018 In power cloud environment, the existing Ciphertext-Policy Attribute-Based Encryption (CP-ABE) access control schemes, do not consider the generation of access structure and the existence of malicious users. To tackle these problems, a power cloud access

Forward-secure ciphertext-policy attribute-based encryption scheme
Tongxin xuebao, 2014 To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed.

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT In epidemiological studies, obsessive‐compulsive disorder (OCD) is robustly associated with increased risk of cardiometabolic disorders, including cardiovascular diseases, type 2 diabetes, and obesity. However, the mechanisms behind these associations are unclear. We conducted genetic correlation analyses to explore shared genetic etiology and

Limnology and Oceanography: Methods, EarlyView.Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry
Mass Spectrometry Reviews, EarlyView.ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

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.

Instantaneous Proxy-Based Key Update for CP-ABE
2016 IEEE 41st Conference on Local Computer Networks (LCN), 2016 Attribute Based Encryption (ABE) scheme has been proposed to implement cryptographic fine grained access control to shared information. It allows to share information of type one-to-many users, without considering the number of users and their identities.
