Certificateless short sequential and broadcast multisignature schemes using elliptic curve bilinear pairings

Journal of King Saud University: Computer and Information Sciences, 2014
Several certificateless short signature and multisignature schemes based on traditional public key infrastructure (PKI) or identity-based cryptosystem (IBC) have been proposed in the literature; however, no certificateless short sequential (or serial ...

Analysis of Error Impact for Batch Handover Authentication Protocols in Mobile Wireless Networks

IEEE Access, 2020
The handover authentication protocol controls the access of multiple access points in a mobile wireless network (MWN). PairHand is a handover authentication protocol that uses identity-based public key cryptography based on bilinear pairing and provides ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Distortion maps for supersingular genus two curves

Journal of Mathematical Cryptology, 2009
Distortion maps are a useful tool for pairing based cryptography. Compared with elliptic curves, the case of hyperelliptic curves of genus g > 1 is more complicated, since the full torsion subgroup has rank 2g.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

The monodromy pairing and discrete logarithm on the Jacobian of finite graphs

Journal of Mathematical Cryptology, 2010
Every graph has a canonical finite abelian group attached to it. This group has appeared in the literature under a variety of names including the sandpile group, critical group, Jacobian group, and Picard group.

A pairing-free identity-based two-party authenticated key agreement protocol for secure and efficient communication

Journal of King Saud University: Computer and Information Sciences, 2017
Recently, many identity-based two-party authenticated key agreement (ID-2PAKA) protocols using elliptic curve cryptography (ECC) have been proposed, however, these protocols do not provide adequate security and their computation costs are also relatively

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Efficient and Provable Secure Pairing-Free Security-Mediated Identity-Based Identification Schemes

The Scientific World Journal, 2014
Security-mediated cryptography was first introduced by Boneh et al. in 2001. The main motivation behind security-mediated cryptography was the capability to allow instant revocation of a user’s secret key by necessitating the cooperation of a security ...
