A first Step towards a Protection Profile for the Security Evaluation of Consensus Mechanisms 建立共识机制安全评估保护概要的第一步
Christine Hennebert
While numerous studies deepen the security issues of the distributed consensus mechanisms, the lack of a normalized reference for their security evaluation makes it difficult to exploit their conclusions. In this paper, the author applies the rigorous standardized methodology of the Common Criteria to consensus mechanisms and defines the security problem to introduce a Protection Profile focused on a peer node as physical device, in its blockchain environment. The aim is to focus on the security assessment of a physical peer device in a distributed network. The further goal is to succeed in defining shared relevant evaluation metrics.
虽然许多研究加深了分布式共识机制的安全问题,但缺乏对其安全评估的规范化参考,使得难以利用其结论。在本文中,作者将通用标准的严格标准化方法应用于共识机制,并定义了安全问题,在其区块链环境中引入了一个专注于对等节点作为物理设备的保护配置文件。其目的是关注分布式网络中物理对等设备的安全评估。进一步的目标是成功地定义共享的相关评估指标。

Data-driven Decision Support Tools for Reducing GHG Emissions from Livestock Production Systems: Overview and Challenges 减少畜牧业生产系统温室气体排放的数据驱动决策支持工具:概述和挑战
Drisya Alex Thumba, S. Lazarova-Molnar, P. Niloofar
Livestock sector is known for its contribution to environmental pollution. A large portion of anthropogenic emissions is from livestock-related activities, such as animal feeding and manure management. According to the Food and Agriculture Organization of the United Nations, by 2050, 73% increase in livestock product consumption is anticipated. This poses an alarming threat to the environmental sustainability as a proportionate increase in greenhouse gases (GHG) emission is also expected. On the bright side, with the support of appropriate technologies and mitigation strategies, the livestock production sector is capable of achieving a substantial reduction in the level of emissions. A consistent quantitative analysis of emissions and related activities can help in identifying the sensitive areas to intervene. There are several data-driven decision support tools and practices available in literature that aim to help farmers contribute to sustainability. In this work, we provide an overview of the popular data-driven modelling techniques and decision support tools used to estimate GHG emissions from the various livestock farming-related sources. We also discuss the role of decision support tools in various management activities, such as analysing and designing farm systems trials and integrating environmental, technological and economic aspects. Finally, we discuss the challenges and opportunities in using data for decision support in reducing GHG emissions in livestock farming.
畜牧业对环境污染的贡献是众所周知的。很大一部分人为排放来自与牲畜有关的活动,如动物饲养和粪便管理。根据联合国粮食及农业组织的数据,到2050年,预计畜产品消费量将增加73%。这对环境的可持续性构成了令人担忧的威胁,因为预计温室气体(GHG)排放也会相应增加。好的一面是,在适当技术和缓解战略的支持下,畜牧生产部门能够大幅减少排放水平。对排放和相关活动进行一致的定量分析有助于确定需要干预的敏感领域。文献中有一些数据驱动的决策支持工具和实践,旨在帮助农民为可持续发展做出贡献。在这项工作中,我们概述了常用的数据驱动建模技术和决策支持工具,用于估算各种畜牧业相关来源的温室气体排放。我们还讨论了决策支持工具在各种管理活动中的作用,例如分析和设计农场系统试验以及整合环境,技术和经济方面。最后,我们讨论了利用数据为减少畜牧业温室气体排放的决策支持所面临的挑战和机遇。

Sequential Routing Decision with Low-Complexity for Throughput Improvement in Full-duplex Cognitive Radio Networks 面向全双工认知无线网络吞吐量提高的低复杂度顺序路由决策
Sharhabeel H. Alnabelsi, H. Salameh
Routing in Cognitive Radio Networks (CRNs) has recently become more efficient, due to employing the Full-Duplex (FD) transmission technology. When the unlicensed users, also known as Secondary Users (SUs), have FD capabilities, they can transmit and receive simultaneously either over the same channel, namely in-band FD (IB-FD), or over different channels, namely Out-of-Band FD (OB-FD). In this work, we adopt the OB-FD transmission, because it is less complex than IBFD, i.e.; it does not require Self-Interference-Cancellation (SIC) technique, also the hardware cost of devices that support IB-FD capability is more expensive. Apparently, channels assignment for the discovered route is crucial, whether it satisfies the FD transmission condition or not. For the OB-FD transmission, for every segment of three-consecutive hops along the route, their selected three channels must be different in order to avoid interference between SUs. Therefore, in this work, we are motivated to propose a sequential mechanism with low-complexity that is aware about FD when assigning channels, namely Sequential FD-(SFD)-aware. According to the proposed protocol, for each candidate route, channels are assigned to route hops sequentially such that the aforementioned condition is satisfied. However, if this condition is not satisfied, the route will not be adopted. It is worth mentioning that there are some methods studied recently in literature for channels assignments, however, these methods require optimization techniques that have NP-hard complexity in terms of number of hops and channels. We compared our proposed protocol with an existing protocol which assigns for each hop the available channel with maximum rate, and then selects the route that has the maximum bottleneck rate. The simulation results show that our proposed mechanism outperforms the baseline protocol in terms of achieved end-to-end throughput.
由于采用全双工(FD)传输技术,认知无线网络(crn)中的路由最近变得更加高效。当未授权用户(Secondary user)具有FD功能时,可以通过同一通道(IB-FD)同时发送和接收,也可以通过不同通道(OB-FD)同时发送和接收。在这项工作中,我们采用OB-FD传输,因为它比IBFD更简单,即;它不需要自干扰消除(SIC)技术,而且支持IB-FD功能的设备的硬件成本更昂贵。显然,无论发现的路由是否满足FD传输条件,其信道分配都是至关重要的。对于OB-FD传输,对于路由上连续三跳的每一段,它们选择的三个信道必须不同,以避免su之间的干扰。因此,在这项工作中,我们提出了一种低复杂度的顺序机制,在分配通道时可以感知FD,即顺序FD-(SFD)感知。根据所提出的协议,对于每个候选路由,依次将信道分配给路由跳,以满足上述条件。但是,如果不满足此条件,则不会采用该路由。值得一提的是,最近文献中研究了一些信道分配的方法,然而,这些方法需要在跳数和信道数方面具有NP-hard复杂性的优化技术。我们将提出的协议与现有的协议进行了比较,该协议为每一跳分配最大速率的可用信道,然后选择具有最大瓶颈速率的路由。仿真结果表明,我们提出的机制在实现端到端吞吐量方面优于基线协议。

Decentralized Linked Open Data in Constrained Wireless Sensor Networks 约束无线传感器网络中的分散链接开放数据
Bart Moons, Flor Sanders, Thijs Paelman, J. Hoebeke
Data generated by sensors in Internet of Things ecosystems contains lots of valuable information, which is often not used to its full potential. This is mainly due to the fact that data is stored in proprietary storages and formats. Manufacturers of sensor devices often offer closed platforms to view and manage the data, which limits their reusability. Moreover, questions start to raise about true data ownership over data generated from monitoring our everyday lives. In order to overcome these issues several initiatives have emerged in the past to hand over data to the rightful owner. One of these initiatives is Solid, currently focusing on socially linked data. However, never before did one apply the Solid principles to Internet of Things data. Therefore, in this paper, a novel approach is presented where sensor data is handled from sensor to storage using open data formats and standards to ensure interoperability and reusability. It is shown that combining existing concepts can be helpful in designing decentralized Internet of Things data storages, on top of which data can be incorporated into the Linked Open Data cloud. This has been done by comparing the overhead of a regular approach, using Linked Open Data concepts on top of a sensor device, to an approach that was optimized for device management in constrained Internet of Things networks.
物联网生态系统中传感器产生的数据包含大量有价值的信息,这些信息往往没有得到充分利用。这主要是由于数据存储在专有存储和格式中。传感器设备制造商通常提供封闭的平台来查看和管理数据,这限制了它们的可重用性。此外,人们开始质疑监控我们日常生活所产生的数据的真正所有权。为了克服这些问题,过去出现了一些将数据移交给合法所有者的倡议。Solid就是其中之一,目前专注于社交关联数据。然而,从未有人将Solid原则应用于物联网数据。因此,本文提出了一种新的方法,使用开放的数据格式和标准将传感器数据从传感器处理到存储,以确保互操作性和可重用性。结果表明,结合现有概念有助于设计分散的物联网数据存储,并在此基础上将数据纳入关联开放数据云。这是通过比较常规方法的开销来完成的,在传感器设备上使用链接开放数据概念,与在受限的物联网网络中优化设备管理的方法。

AppArmor For Health Data Access Control: Assessing Risks and Benefits 健康数据访问控制:评估风险和收益
Thibaud Ecarot, Samuel Dussault, Ameni Souid, L. Lavoie, J. Éthier
The AppArmor Linux Security Module (LSM) is widely used on Linux operating systems as it, among other things, provides mandatory access control (MAC) and isolates processes. This isolation helps meet the privacy requirements for critical applications. These application security policies are defined with profiles loaded into the Linux system kernel. However, these access control mechanisms are far from covering all the rising demands for confidentiality enforcement regarding critical applications. This paper conducts a risks and benefits analysis to assess whether a healthcare infrastructure can safely rely on the AppArmor LSM to protect its sensitive data. Thus, the general architecture of AppAmor comes to be detailed. Then, a static code analysis is performed to study the data structures found in the LSM. Finally, the outbreak of would-be side-channel attacks from userspace is discussed while offering mitigation methods. The result of this analysis shows that the AppArmor LSM is susceptible to side-channel attacks and should be used as part of a more comprehensive defense-in-depth strategy.
AppArmor Linux Security Module (LSM)广泛用于Linux操作系统,因为它提供了强制访问控制(MAC)和隔离进程等功能。这种隔离有助于满足关键应用程序的隐私要求。这些应用程序安全策略是通过加载到Linux系统内核中的配置文件定义的。然而,这些访问控制机制远远不能满足关键应用程序的所有日益增长的保密要求。本文进行了风险和收益分析,以评估医疗保健基础设施是否可以安全地依赖AppArmor LSM来保护其敏感数据。因此,详细介绍了AppAmor的总体架构。然后,执行静态代码分析来研究LSM中发现的数据结构。最后,讨论了来自用户空间的潜在侧通道攻击的爆发,同时提供了缓解方法。分析结果表明,AppArmor LSM容易受到侧信道攻击,应该作为更全面的纵深防御策略的一部分使用。

A Survey on Blockchain for Healthcare Informatics and Applications 区块链在医疗保健信息学及其应用中的研究
K. Wilber, Sarah Vayansky, N. Costello, David Berdik, Y. Jararweh
Blockchain, cryptographically linked blocks of data, is the key technology behind the infamous cryptocurrency Bitcoin, however, blockchain can serve more use cases than just cryptocurrency. The technology has use cases in any industry that generates and transfers data. In a use case such as cryptocurrency the blockchain is used to manage transactions from peer-to-peer in a way that does not allow for that transaction’s data to be manipulated by one of the involved parties or a third party. This is a valuable process that other industries could leverage. One such industry that could benefit from applying blockchain technology for a multitude of cases is the healthcare industry. Primary care doctors could be connected to a blockchain system that allowed them to access patient data and securely monitor the respective patient, pharmaceutical companies could increase their products validity in the marketplace with individual product tracking, and the insurance industry could trust all the information about a client. All of these are possible use cases for blockchain in the healthcare industry. Currently, the healthcare industry is not leveraging the blockchain at scale. Within this paper we are going to explore the possibilities for blockchain technology and the use cases in the healthcare industry specifically, and how the different industries within the healthcare industry can implement a blockchain system.
区块链,加密链接的数据块,是臭名昭著的加密货币比特币背后的关键技术,然而,区块链可以服务于更多的用例,而不仅仅是加密货币。该技术在任何产生和传输数据的行业都有用例。在加密货币等用例中,区块链用于管理点对点交易,其方式不允许交易数据被其中一方或第三方操纵。这是一个有价值的过程,其他行业可以加以利用。医疗保健行业是一个可以从将区块链技术应用于众多案例中受益的行业。初级保健医生可以连接到区块链系统,使他们能够访问患者数据并安全地监控各自的患者,制药公司可以通过个人产品跟踪来提高其产品在市场上的有效性,保险业可以信任客户的所有信息。所有这些都是区块链在医疗保健行业的可能用例。目前,医疗保健行业并没有大规模利用区块链。在本文中,我们将探索区块链技术的可能性,特别是医疗行业的用例,以及医疗行业内的不同行业如何实现区块链系统。

Primary care doctors could be connected to a blockchain system that allowed them to access patient data and securely monitor the respective patient, pharmaceutical companies could increase their products validity in the marketplace with individual product tracking, and the insurance industry could trust all the information about a client. All of these are possible use cases for blockchain in the healthcare industry. Currently, the healthcare industry is not leveraging the blockchain at scale. Within this paper we are going to explore the possibilities for blockchain technology and the use cases in the healthcare industry specifically, and how the different industries within the healthcare industry can implement a blockchain system.","PeriodicalId":147136,"journal":{"name":"2020 7th International Conference on Internet of Things: Systems, Management and Security (IOTSMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125535602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Security and Privacy of Medical Internet of Things Devices for Smart Homes 智能家居医疗物联网设备的安全和隐私
Paige Harvey, Otily Toutsop, K. Kornegay, Excel Alale, Don Reaves
The Internet of Things, IoT, provides various applications in the health and care sector, enhancing assisted living, and the ability to remotely monitor patients in hospitals, at homes, and in care facilities [1]. Additionally, many patients who require constant health monitoring prefer the comfort of home monitoring to hospital environments [2]. Therefore, with the increased interest in smart home configurations and the need for Medical IoT, MIoT, device development, we may witness a rise in in-home smart healthcare set-ups. In this paper, we present a Ph.D. research proposing an improve architecture for ensuring security and privacy of smart medical devices in smart home environments.
物联网(IoT)在健康和护理领域提供了各种应用,增强了辅助生活,以及在医院、家庭和护理机构远程监控患者的能力[1]。此外,许多需要持续健康监测的患者更喜欢舒适的家庭监测,而不是医院环境[2]。因此,随着人们对智能家居配置的兴趣增加,以及对医疗物联网、物联网、设备开发的需求,我们可能会看到家庭智能医疗保健设置的增加。在本文中,我们提出了一项博士研究,提出了一种改进的架构,以确保智能家居环境中智能医疗设备的安全性和隐私性。
