Unidirectional Variable Threshold Proxy Re-signature Scheme with Provable Security [PDF]

Jisuanji gongcheng, 2016
In most existing threshold proxy re-signature schemes,threshold value is essentially immutable.However,depending on the significance of re-signature message,the value should be changed dynamically in many practical applications.Based on proxy re ...

Practical and Provably Secure Distance-Bounding [PDF]

Journal of Computer Security, 2015
Abstract From contactless payments to remote car unlocking, many applications are vulnerable to relay attacks. Distance bounding protocols are the main practical countermeasure against these attacks. In this paper, we present a formal analysis of SKI, which recently emerged as the first family of lightweight and provably secure ...

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

MRCC: A Practical Covert Channel Over Monero With Provable Security

IEEE Access, 2021
Covert channels are designed to protect the communication relationship of the sender and receiver. Traditional covert channels have become insecure due to the continuous improvement of traffic analysis techniques. In this context, there is an urgent need

On Provable Security for Conventional Cryptography

, 2000
Many previous results on the provable security of conventional cryptography have been published so far. We provide here handy tools based on Decorrelation Theory for dealing with them and we show how to make their proof easier.

Public Attitudes Toward Compassionate Release of Older People From Prison: Findings From a National Survey in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT The rapid increase in older people in prison populations worldwide is generating significant health, cost, and human rights pressures on custodial systems. Compassionate release for older, frail inmates is a potentially effective response, yet little is known about public support for this approach.

Efficient identity-based authenticated key agreement protocol with provable security for vehicular ad hoc networks

International Journal of Distributed Sensor Networks, 2018
In vehicular ad hoc networks, establishing a secure channel between any two vehicles is fundamental. Authenticated key agreement is a useful mechanism, which can be used to negotiate a shared key for secure data transmission between authentic vehicles in

Cerebral No‐Reflow after Thrombectomy: International Delphi Consensus on Definition and Imaging Assessment

Annals of Neurology, EarlyView.
Background The operational definition and imaging assessment of the no‐reflow phenomenon, a potential contributor to poor clinical outcome despite successful thrombectomy, remains debated. We aimed to develop expert‐based international consensus on the definition, assessment, and reporting standard of cerebral no‐reflow post‐thrombectomy. Methods Three‐

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability. Existing Safe‐and‐Sustainable‐by‐Design
