Flexible Attribute-Based Encryption [PDF]

, 2012
In this paper, we propose a notion of flexible attribute-based encryption. Flexible attribute-based encryption is a variant of ciphertext-policy ABE, which allows one to loosen a decryption policy underlying a given ciphertext, if one knows some system-wide trapdoor information, without knowing its underlying plaintext message.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Fine-grained attribute update and outsourcing computing access control scheme in fog computing

Tongxin xuebao, 2021
To slove the problem that in the fog computing environment with comparatively high low latency demand, ciphertext policy attribute based encryption (CP-ABE) faced the problems of high encryption and decryption overhead and low efficiency of attribute ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Ciphertext-policy Weighted Attribute-based Encryption Scheme in Cloud Computing

工程科学与技术, 2013
:By analyzing existing ciphertext-policy attribute-based encryption scheme, ciphertext-policy weighted attribute-based encryption scheme was proposed. To solve the existing scheme without considering the attribute with weight, the concept of weight was ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Targeted Homomorphic Attribute-Based Encryption

, 2016
In key-policy attribute-based encryption ABE, messages are encrypted respective to attributes x, and keys are generated respective to policy functions f. The ciphertext is decryptable by a key only if $$fx=0$$fx=0. Adding homomorphic capabilities to ABE is a long standing open problem, with current techniques only allowing compact homomorphic ...

Revocable and Decentralized Attribute-Based Encryption

The Computer Journal, 2016
In this paper, we propose a revocable and decentralized attribute-based encryption (ABE) system that splits the task of decryption key generation across multiple attribute authorities (AAs) without requiring any central party such that it achieves attribute revocation by simply stopping updating of the corresponding private key.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
