Efficient Equality Test on Identity-Based Ciphertexts Supporting Flexible Authorization

open access: yesEntropy, 2023
In the cloud, uploading encrypted data is the most effective way to ensure that the data are not leaked. However, data access control is still an open problem in cloud storage systems.

Toward Hierarchical Identity-Based Encryption [PDF]

open access: yes, 2002
We introduce the concept of hierarchical identity-based encryption (HIBE) schemes, give precise definitions of their security and mention some applications. A two-level HIBE (2-HIBE) scheme consists of a root private key generator (PKG), domain PKGs and users, all of which are associated with primitive IDs (PIDs) that are arbitrary strings.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

An Improvement on the BGH Cryptosystem

open access: yesMathematics
The three main IBE schemes, i.e., Boneh–Franklin, Cocks and Boneh–Gentry–Hamburg present both strengths and weaknesses. In this paper, we introduce a more efficient variant of BGH (while preserving receiver’s anonymity) based on the work of Jhanwar and ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Identity Based Group Signatures from Hierarchical Identity-Based Encryption [PDF]

open access: yes, 2009
A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures.

Identity-Based Encryption for Sensor Networks [PDF]

open access: yesFifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07), 2007
In spite of several years of intense research, the area of security and cryptography in wireless sensor networks (WSNs) still has a number of open problems. On the other hand, the advent of identity-based encryption (IBE) has enabled a wide range of new cryptographic solutions. In this work, we argue that IBE is ideal for WSNs and vice versa.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

On the Power of Hierarchical Identity-Based Encryption [PDF]

open access: yes, 2016
We prove that there is no fully black-box construction of collision-resistant hash functions CRH from hierarchical identity-based encryption HIBE with arbitrary polynomial number of identity levels. To the best of our knowledge this is the first limitation proved for HIBE.
