A prototype of adaptive virtual environments therapy system (AVET) was developed which will enable innovative Virtual Reality (VR)-based therapy approach for children with attention deficit on the autism spectrum. Many systems have successfully used VR in Autism Spectrum Disorders (ASD) therapies. Most of them use VR as an alternative way to conduct therapies by simulating traditional therapies or real-life experiences. The AVET employed VR-exclusive "impossible experiences" (e.g., a chair that deforms upon the user's gaze, a transparent human) which are not available in real world. The AVET identifies, influences the user's cognition, and delivers a customized Prolonged Exposure (PE)-style VR therapy for children with attention deficits on the autism spectrum. We conducted a preliminary evaluation to the current AVET prototype with the experts. Based on the interview feedbacks, we anticipate the AVET will have a great potential to deliver innovative and effective ASD attention training therapies.

software engineering is inherently a human-centric and collaborative process and this reflects in its teaching programs, as most of the courses comprise projects and team efforts. In order to fairly evaluate students, there is the problem of quantifying the amount of work contributed to the team development project by each of its members. Most commonly, in order to estimates student contributions, instructors use arbitrary and subjective judgment derived from observations and evaluations. The currently used process is not a complete picture and is time consuming since it requires numerous observations and extensive paperwork's review. Emerging decentralized systems (such as git) and their widespread applications in all realms of development which capitalize on team-aware metrics, are worthwhile and can provide a solution to the problem. In this work we support a solution that utilizes git-driven technology, and its related features, to measure a team member's contributions objectively, based not only upon the completion of the project, but also at any time during progression development. Such performance assessment could generate more productive team-based learning with higher-quality graduates for better meeting software industry's expectations.

Blockchains are turning into decentralized computing platforms and are getting worldwide recognition for their unique advantages. There is an emerging trend beyond payments that blockchains could enable a new breed of decentralized applications, and serve as the foundation for Internet's security infrastructure. The immutable nature of the blockchain makes it a winner on security and transparency;it is nearly inconceivable for ledgers to be altered in a way not instantly clear to every single user involved. However, most blockchains fall short in privacy aspects, particularly in data protection. Garlic Routing and Onion Routing are two of major Privacy Enhancing Techniques (PETs) which are popular for anonymization and security. Garlic Routing is a methodology using by I2P Anonymous Network to hide the identity of sender and receiver of data packets by bundling multiple messages into a layered encryption structure. The Onion Routing attempts to provide lowlatency Internet-based connections that resist traffic analysis, deanonymization attack, eavesdropping, and other attacks both by outsiders (e.g. Internet routers) and insiders (Onion Routing servers themselves). As there are a few controversies over the rate of resistance of these two techniques to privacy attacks, we propose a PET-Enabled Sidechain (PETES) as a new privacy enhancing technique by integrating Garlic Routing and Onion Routing into a Garlic Onion Routing (GOR) framework suitable to the structure of blockchains. The preliminary proposed GOR aims to improve the privacy of transactions in blockchains via PETES structure. Copyright © 2019, The Authors. All rights reserved.

Dehghantanha, Ali Choo, Kim-Kwang Raymond Faculty of Computer Engineering University of Isfahan Iran Department of Software Engineering and Game Development Kennesaw State University GA30060 United States Cyber Science Lab School of Computer Science University of Guelph ON Canada Department of Information Systems and Cyber Security University of Texas at San Antonio TX United States

5G mobile networks provide additional benefits in terms of lower latency, higher data rates, and more coverage, in comparison to 4G networks, and they are also coming close to standardization. For example, 5G has a new level of data transfer and processing speed that assures users are not disconnected when they move from one cell to another;thus, supporting faster connection. However, it comes with its own technical challenges relating to resource management, authentication handover and user privacy protection. In 5G, the frequent displacement of the users among the cells as a result of repeated authentication handovers often lead to a delay, contradicting the 5G objectives. In this paper, we propose a new authentication approach that utilizes blockchain and software defined networking (SDN) techniques to remove the re-authentication in repeated handover among heterogeneous cells. The proposed approach is designed to assure the low delay, appropriate for the 5G network in which users can be replaced with the least delay among heterogeneous cells using their public and private keys provided by the devised blockchain component while protecting their privacy. In our comparison between Proof-of-Work (POW)-based and network-based models, the delay of our authentication handover was shown to be less than 1ms. Also, our approach demonstrated less signaling overhead and energy consumption compared to peer models. Copyright © 2019, The Authors. All rights reserved.

作者： Parizi, Reza M. Department of Software Engineering Game Development Kennesaw State University MariettaGA30060 United States

Microservices become a fast growing and popular architectural style based on service-oriented development. One of the major advantages using component-based approaches is to support reuse. In this paper, we present a study of microservices and how these systems are related to the traditional abstract models of component-based systems. This research focuses on the core properties of microservices including their scalability, availability and resilience, consistency, coupling and cohesion, and data storage capability, while highlighting their limitations and challenges in relation to components. To support our study, we investigated the existing literature and provided potential directions and interesting points in this growing field of research. As a result, using microservices as components is promising and would be a good mechanism for building applications that were used to be built with component-based approaches.

The dramatic growth in smartphone malware shows that malicious program developers are shifting from traditional PC systems to smartphone devices. Therefore, security researchers are also moving towards proposing novel antimalware methods to provide adequate protection. This paper proposes a Blockchain-Based Malware Detection Framework (B2MDF) for detecting malicious mobile applications in mobile applications marketplaces (app stores). The framework consists of two internal and external private blockchains forming a dual private blockchain as well as a consortium blockchain for the final decision. The internal private blockchain stores feature blocks extracted by both static and dynamic feature extractors, while the external blockchain stores detection results as blocks for current versions of applications. B2MDF also shares feature blocks with third parties, and this helps antimalware vendors to provide more accurate solutions. Copyright © 2019, The Authors. All rights reserved.

Blockchain is a new trend rising fast from the community and the enterprise world. As an infrastructural technology it is finding its way into a growing number of domains like finance, medical, digital marketplace, pharmaceutical and government agencies. While blockchain technology is primarily thought as the foundation of Bitcoin, it has grown far beyond underpinning the virtual currency. It promises building better trust, transparency, and integrity without a third-party and the risk of censorship. These remarkable advantages do however come at a price. The blockchain ecosystem is riddled with human-centric and economical issues for its participants, leading to unintended consequences in decentralized networks. Gamified software engineering is a growing field that in particular taps into gamification technology, the application of game mechanics in non-game contexts, to address human-related concerns. There are currently no studies around blockchain that have been identified to have a clear view of existing research and solutions for utilizing the gamification in the emerging blockchain systems. As a first step towards filling this gap, this paper discusses and identifies two major human-based problems in the blockchain decentralized applications and development. For those problems, it proposes a preliminary gamified model to provide a basis for expanding future research and applications in this joint domain.

Journal of Physics: Conference Series 2019年第2期1237卷

作者： Shengjian Liu Yan Yang Lin Luo Department of Game Design South China Institute of Software Engineering Guangzhou University Guangzhou GuangDong 510990 China

Aiming at the characteristics of multi-dimensional knapsack problem, the widely used bare bones particle swarm optimization algorithm is discretized, and the traditional objective function based on large penalty parameters is improved. The infeasible solution is transformed into a feasible solution by using the repair mechanism. The typical examples of 10 multi-dimensional knapsack problems are simulated and compared with four intelligent optimization algorithms. The simulation results show that the discrete bare bones particle swarm optimization algorithm has good convergence efficiency, high precision and good robustness when solving multi-dimensional knapsack problem.

Empirical vulnerability analysis of automated smart contracts security testing on blockchains

arXiv

arXiv 2018年

作者： Parizi, Reza M.

The emerging blockchain technology supports decentralized computing paradigm shift and is a rapidly approaching phenomenon. While blockchain is thought primarily as the basis of Bitcoin, its application has grown far beyond cryptocurrencies due to the introduction of smart contracts. Smart contracts are self-enforcing pieces of software, which reside and run over a hosting blockchain. Using blockchain-based smart contracts for secure and transparent management to govern interactions (authentication, connection, and transaction) in Internet-enabled environments, mostly IoT, is a niche area of research and practice. However, writing trustworthy and safe smart contracts can be tremendously challenging because of the complicated semantics of underlying domain-specific languages and its testability. There have been high-profile incidents that indicate blockchain smart contracts could contain various code-security vulnerabilities, instigating financial harms. When it involves security of smart contracts, developers embracing the ability to write the contracts should be capable of testing their code, for diagnosing security vulnerabilities, before deploying them to the immutable environments on blockchains. However, there are only a handful of security testing tools for smart contracts. This implies that the existing research on automatic smart contracts security testing is not adequate and remains in a very stage of infancy. With a specific goal to more readily realize the application of blockchain smart contracts in security and privacy, we should first understand their vulnerabilities before widespread implementation. Accordingly, the goal of this paper is to carry out a far-reaching experimental assessment of current static smart contracts security testing tools, for the most widely used blockchain, the Ethereum and its domain-specific programming language, Solidity, to provide the first body of knowledge for creating more secure blockchain-based software.
