Attribute-Based Encryption with Fast Decryption [PDF]

open access: yes, 2013
Attribute-based encryption (ABE) is a vision of public key encryption that allows users to encrypt and decrypt messages based on user attributes. This functionality comes at a cost. In a typical implementation, the size of the ciphertext is proportional to the number of attributes associated with it and the decryption time is proportional to the number

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Revocable and Decentralized Attribute-Based Encryption

open access: yesThe 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.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Dynamic Attribute-based Signcryption without Random Oracles [PDF]

open access: yes, 2012
IIn SCN2010, Gagné, Narayan, and Safavi–Naini proposed attribute–based signcryption (ABSC) with threshold structure. As in ciphertext–policy attribute–based encryption (CP–ABE), an encryptor can specify the access structure of decryptors, and as in ...

BDABE - Blockchain-based Distributed Attribute based Encryption

open access: yes, 2022
S.99-110Attribute Based Encryption (ABE) denotes asymmetric cryptographic schemes where key pairs are created for attribute owners and often applied to realize a fine-grained, cryptographic access control mechanism for outsourced data.

Securing Financial XML Transactions Using Intelligent Fuzzy Classification Techniques [PDF]

open access: yes
The eXtensible Markup Language (XML) has been widely adopted in many financial institutions in their daily transactions; this adoption was due to the flexible nature of XML providing a common syntax for systems messaging in general and in financial ...

Quantum Key-Policy Attribute-based Encryption [PDF]

open access: yes, 2017
Attribute-Based Encryption is a relatively new concept in the field of cryptography, and it allows only the authorized entities to decrypt a message. This type of encryption is the mechanism by which the users may encrypt and decrypt data based on user ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
