A distributed key establishment scheme for wireless mesh networks using identity-based cryptography [PDF]
, 2010 In this paper, we propose a secure and efficient key establishment scheme designed with respect to the unique requirements of Wireless Mesh Networks. Our security model is based on Identity-based key establishment scheme without the utilization of a ...

Secret Sharing and Proactive Renewal of Shares in Hierarchical Groups
, 2010 Secret sharing in user hierarchy represents a challenging area for research. Although a lot of work has already been done in this direc- tion, this paper presents a novel approach to share a secret among a hierarchy of users while overcoming the ...

Rational-security and fair two-party comparison protocol
Tongxin xuebao, 2023 Existing secure two-party comparison protocols usually allowed one party (e.g., Alice) to obtain a comparison result first, and then Alice informed the other one (e.g., Bob) of the comparison result.Obviously, if Alice refused or failed to send the ...

Orthogonal-state-based cryptography in quantum mechanics and local post-quantum theories
, 2015 We introduce the concept of cryptographic reduction, in analogy with a similar concept in computational complexity theory. In this framework, class $A$ of crypto-protocols reduces to protocol class $B$ in a scenario $X$, if for every instance $a$ of $A$,

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Obfuscating encrypted threshold signature algorithm and its applications in cloud computing.
PLoS ONE, 2021 Current cloud computing causes serious restrictions to safeguarding users' data privacy. Since users' sensitive data is submitted in unencrypted forms to remote machines possessed and operated by untrusted service providers, users' sensitive data may be ...

Data Confidentiality in Mobile Ad hoc Networks [PDF]
, 2012 Mobile ad hoc networks (MANETs) are self-configuring infrastructure-less networks comprised of mobile nodes that communicate over wireless links without any central control on a peer-to-peer basis.
