Homomorphic signature schemes for single-source and multi-source network coding

open access: yesTongxin xuebao, 2019
To solve the problems of pollution attacks of single-source and multi-source network coding,two homomorphic signature schemes for network coding were proposed.In homomorphic signature for single-source network,the message hash value was signed on the ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

A Multi-policy Threshold Signature Scheme with Traceable Participant Cosigners

open access: yes, 2009
[[abstract]]In a (t, n) threshold scheme, the secret can be reconstructed by the cooperation of t or more users. With this basic concept, Lee devised a threshold signature scheme with multiple signing policies in 2001.

A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

Universality of a mesenchymal transition signature in invasive solid cancers

open access: yes, 2012
In this brief communication, additional computational validation is provided consistent with the unifying hypothesis that a shared biological mechanism of mesenchymal transition, reflected by a precise gene expression signature, may be present in all ...

A New Digital Signature Scheme Based on Mandelbrot and Julia Fractal Sets. [PDF]

open access: yes, 2007
This paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Off-line signature verification

open access: yes, 2009
In today’s society signatures are the most accepted form of identity verification. However, they have the unfortunate side-effect of being easily abused by those who would feign the identification or intent of an individual.

An Aggregate Signature Scheme Based on a Trapdoor Hash Function for the Internet of Things

open access: yesSensors, 2019
With the rapid development of the Internet of Things (IoT), it becomes challenging to ensure its security. Identity authentication and integrity verification can be achieved by secure hash functions and digital signature algorithms for IoT applications ...
