Physical Uncloneable Functions (PUF) are systems whose physical behavior to different inputs can be measured reliably, yet cannot be cloned in a physical replica. Existing designs propose to derive uncloneability from an assumed practical impossibility of exactly replicating inherent manufacturing variations, e.g., between individual chipset instances. The PUF promise has drawn significant atte...

Pervasive environments are comprised of resource-constrained mobile devices “limited” in their connectivity to other devices or networks due to the inherent dynamic nature of the environment. Limited connectivity to the Internet precludes the use of conventional security mechanisms like Certifying Authorities and other forms of server-centric authentication. Under these circumstances peer-to-pe...

Despite of their rising popularity, current cloud storage services and cloud-backed storage systems still have some limitations related to reliability, durability assurances and inefficient file sharing. We present SCFS, a cloud-backed file system that addresses these issues and provides strong consistency and near-POSIX semantics on top of eventually-consistent cloud storage services. SCFS pro...

The authors suggest using a trust-overlay network over multiple data centers to implement a reputation system for establishing trust between service providers and data owners. In this paper, we investigate the problem of data security in cloud data storage, which is essentially a distributed storage system. To achieve the assurances of cloud data integrity and availability and enforce the quali...

Guidance on the prevention of hyponatraemia in children was issued by DHSSPSNI in March 2002. Two years later Dr Henrietta Campbell, the Chief Medical Officer, wrote to the Chief Executives of acute and combined trusts to seek assurances that the guideline had been incorporated into clinical practice and its implementation monitored. This paper reports the findings of the first prospective stud...

I loosely define "hard" information defenses as those assurance mechanisms that tend more to prevent (rather than recover from) the ill effects of security breaches and which tend to be more static in nature. Similarly, I loosely define "soft" defenses as assurances that tend to rely more on recovery from security breaches and offer a more dynamic/adaptive kind of information protection. Inform...

Indonesian halal product regulation has changed. These arrangements have been in numerous rules, but they not binding and strong legal instruments. Halal assurances the micro industry, especially Depok City, are continually failing. Sate Taichan Cihuy Mie Ayam Pelita Solo production research demonstrates that promises failed. Doctrinal study uses qualitative data for normative research. The exa...

Colombia’s very strong policy frameworks and comprehensive response to the pandemic have supported economy’s resilience. With stronger-than-expected growth last year, fiscal deficits public debt are declining faster than anticipated, framework has been reactivated with a new rule anchor. Further monetary tightening should drive inflation towards central bank’s target by mid-2024. Successful cre...

There is a need for the UK and EU to continue mutual assistance in criminal matters. As Member State, matters between was primarily governed by an convention. This convention builds on existing Council of Europe conventions assistance. With now outside EU’s data protection architecture, this may pose significant hurdle future cooperation. article critically analyses adequacy decision from engag...
