Secure key Agreement for Group Communications
, 2008 --Many key establishment protocols have been proposed for secure group communications. However, these protocols share the limitations that group members are not mutually authenticated, dynamic group membership is not considered, and the cost of key ...

An Improved ID-based Authenticated Group Key Agreement Scheme [PDF]
, 2003 Authenticated group key agreement problem is important in many modern collaborative and distributed applications. There are two ID-based authenticated group key agreement schemes have been proposed by Choi et al.

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.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Practical Supersingular Isogeny Group Key Agreement [PDF]
, 2020 We present the first quantum-resistant $n$-party key agreement scheme based on supersingular elliptic curve isogenies. We show that the scheme is secure against quantum adversaries, by providing a security reduction to an intractable isogeny problem.

Cryptanalysis of Ateniese–Steiner–Tsudik-Authenticated Group Key Management Protocol
Applied SciencesWe present an active attack that targets Ateniese et al.’s authenticated group key agreement, which, as a particular case, includes the well-known multiparty key exchange protocol CLIQUES that allows a group of users to build a common secret using some ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Dynamic Group Key Agreement in Tree-based Setting
, 2005 We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We prove that our protocol is provably secure in the standard security model of

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
