The industrial supply chain networks basically capture the circulation of social resource, dominating the stability and efficiency of the industrial system. In this paper, we provide an empirical study of the topology of smartphone supply chain network. The supply chain network is constructed using open online data. Our experimental results show that the smartphone supply chain network has small-world feature with scale-free degree distribution, in which a few high degree nodes play a key role in the function and can effectively reduce the communication cost. We also detect the community structure to find the basic functional unit. It shows that information communication between nodes is crucial to improve the resource utilization. We should pay attention to the global resource configuration for such electronic production management.

Ransomware attacks are a prevalent cybersecurity threat to every user and enterprise today. This is attributed to their polymorphic behaviour and dispersion of inexhaustible versions due to the same ransomware family or threat actor. A certain ransomware family or threat actor repeatedly utilises nearly the same style or codebase to create a vast number of ransomware versions. Therefore, it is essential for users and enterprises to keep well-informed about this threat landscape and adopt proactive prevention strategies to minimise its spread and affects. This requires a technique to detect ransomware samples to determine the similarity and link with the known ransomware family or threat actor. Therefore, this paper presents a detection method for ransomware by employing a combination of a similarity preserving hashing method called fuzzy hashing and a clustering method. This detection method is applied on the collected WannaCry/WannaCryptor ransomware samples utilising a range of fuzzy hashing and clustering methods. The clustering results of various clustering methods are evaluated through the use of the internal evaluation indexes to determine the accuracy and consistency of their clustering results, thus the effective combination of fuzzy hashing and clustering method as applied to the particular ransomware corpus. The proposed detection method is a static analysis method, which requires fewer computational overheads and performs rapid comparative analysis with respect to other static analysis methods.

As our reliance on large, complex and ubiquitous software system increases, so does the devastating consequences that a cyberattack can have to modern society. Building secure software systems requires a greater need for secure software engineering approaches that can detect and address security vulnerabilities at the earliest stages of the software development life cycle. This paper presents an approach to facilitate the elicitation of cybersecurity requirements based on enhancing the widely adopted technique of use case modeling by incorporating the use of an ontology. The ontology will model the semantic relationship of cybersecurity requirements. Utilizing this ontology, we propose an approach that can be used to reuse and share cybersecurity requirements, providing a potential for the rapid discovery and correction of software vulnerabilities in the development process.

Internet of Things (IoT) enables a plethora of applications. However provisioning these applications in a cost-efficient manner, as well as decoupling the applications from the underlying IoT devices remains a challenge that cloud computing may aid in tackling. This paper proposes an architecture for an IoT Infrastructure as a Service (IaaS) to address these issues. Like any other cloud IaaS, the proposed IaaS relies on virtualization to realize cost efficiency. The high-level Application Programming Interfaces (APIs) that enable IoT cloud consumers (e.g. IoT PaaS) to use the virtualized resources are described, as well as the lower level APIs that make possible the management of the actual pool of IoT physical resources. The subjacent functional entities (e.g. orchestrator, publisher, repository access engine, physical and virtual sensor repositories) are introduced, as well as the related interfaces. A proof of concept prototype is built and performance measurements are made. Advanticsys and Virtenio sensors are used as physical sensors. © 2018 IEEE.

This article discusses the main problems associated with information security in corporate networks and ensuring the reliable operation of information systems and the services they provide. Information security is understood as the security of information resources and information systems, as well as the supporting infrastructure from accidental or deliberate influences of a natural or artificial nature, fraught with harm to the owners or users of information resources. Currently, there are major changes in information security issues. They relate to the methods of work of attackers, the conditions of crimes commited in the computer sphere, as well as the consequences of illegal activities.

The main goal in proteomics is to describe the proteome in a comprehensive and accurate way, and enzymolysis is a key step in the process of large-scale proteomics experiments. For the same protein samples, using different proteases may introduce a strong bias into protein analysis results. This situation will make proteomics experiments irreproducible and will have a serious impact on the experimental results. To reduce this protease bias, we present EMQ (Error-Minimization-based Quantification for Protein), an approach based on error minimization. In contrast to the existing method, our model includes information on shared peptides, which are ubiquitous in mass spectrometric datasets. The abundance of shared peptides will be assigned to related proteins accurately, thereby determining the protein abundance. Based on this feature, we used the proposed model with several datasets, and compared its performance with the other. Finally, our model is shown to have better performance than other approach (average Pearson correlation of ~0.83 obtained by EMQ, while ~0.63 by other model). © VDE VERLAG GMBH - Berlin - Offenbach.

The desire to share and unite remote digital assets motivated the development of the classical internet, the enabler of the entire 21st century economy and our modern way of life. As we enter the quantum era, it is to be expected there will be a similar demand for networking quantum assets, motivating a global quantum internet for bringing together the world's quantum resources, leveraging off their exponential trajectory in capability. We present models for quantum networking, how they might be applied in the future, and the implications they will have. Socially, economically, politically and geostrategically, the upcoming era of quantum supremacy will be as significant for the 21st century as the transistor was for the 20th. The inherently different scaling in the computational power of quantum computers fundamentally changes the dynamics of how they will operate in the future. Given their high expected initial cost, a client/server model for outsourcing computation will be essential for enabling the accessibility and proliferation of this technology, and ensuring its economic viability. We therefore anticipate the emergence of cloud quantum computing, a model for outsourcing quantum computations to the network. We argue that economic efficiency will mandate that all future quantum computers be united into a single global virtual quantum computer, offering exponentially more power to all network participants than if they were to keep their resources to themselves. This model for the allocation of computational resources is uniquely quantum, with no classical analogue, completely altering the economic landscape for the future of computation. Given the sensitivity of much of the data to which future quantum computers are going to foreseeably be applied, protocols for encrypted quantum computation will be essential - the outsourcing of computations that neither an eavesdropper nor even the server performing the computation can spy upon. This will enable new models fo

Indoor Air Quality (IAQ) Sensing Device Prototype: software-Hardware Architecture and Performance

引用

IOP Conference Series: Materials Science and engineering 2019年第1期551卷

作者： A Nor Azhar M Rahmah AH Roslina Z Fauziah Department of Computer Science Faculty of Computer Systems & Software Engineering Universiti Malaysia Pahang Lebuhraya Tun Razak Gambang 26300 Kuantan Pahang Malaysia Department of Graphic & Multimedia Technology Faculty of Computer Systems & Software Engineering Universiti Malaysia Pahang Lebuhraya Tun Razak Gambang 26300 Kuantan Pahang Malaysia Department of Software Engineering Faculty of Computer Systems & Software Engineering Universiti Malaysia Pahang Lebuhraya Tun Razak Gambang 26300 Kuantan Pahang Malaysia

In a green environment, air quality is among the prominent aspects to be considered to prevent pollution and in turn maintain safe air. Sick Building Syndrome (SBS) and Building Related Illness (BRI) are the problems that must be encountered by building occupants. Existing devices are quite expensive, and more attention is needed on monitoring air quality. Therefore, this paper discusses a software-hardware architecture proposal to overcome the existing IAQ data retrieval performance problem. The objective of this work is to analyse the most recent IAQ sensing device developed by the researcher, to evaluate the performance attribute, and to implement the software-hardware architecture based on the Performance-Driven software Architecture Refactoring (PDSAR) method. In order to assess the overall performance of the architecture proposed, the prototype of the Indoor Air Quality (IAQ) sensing device was developed. The testing was performed during a period of six months. The results demonstrate that the average performance for 540 readings is 76.67%. This shows that the architecture can be accepted as a generic IAQ sensing device development structure. The device act as an alternative, cheaper and safer device which can be employed by all building owners in the future.
