Encrypted domain reversible data hiding based on proxy re-encryption in distributed environment

Journal of King Saud University: Computer and Information Sciences
Reversible data hiding in encrypted domain (RDH-ED) addresses data security and privacy protection issues. However, traditional RDH-ED algorithms face challenges in terms of dynamic authorization, multiparty collaboration, and secure sharing in ...

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.

Prêt à Voter with Re-encryption Mixes

, 2006
We present a number of enhancements to the voter verifiable election scheme Pret a Voter [CRS05]. Firstly, we propose a mechanism for the distributed construction by a set of independent clerks of the ballot forms. This construction leads to proto-ballot forms with the candidate list encrypted and ensures that only a collusion of all the clerks could ...

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+.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

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.

Efficient provable dual receiver hybrid and light weight public key schemes based on the discrete logarithm problem without pairings

IET Communications
Dual‐receiver proxy re‐encryption is a cryptographic technique that enables secure data sharing among multiple authorized users or entities. It has gained significant attention for its ability to manage access permissions, data confidentiality, and ...

A New Encrypted Data Switching Protocol: Bridging IBE and ABE Without Loss of Data Confidentiality

IEEE Access, 2019
Encryption technologies have become one of the most prevalent solutions to safeguard data confidentiality in many real-world applications, e.g., cloud-based data storage systems.

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
