Traffic policing is the process of ensuring that network traffic complies with its policies with methods like traffic shaping. As the distribution of sources involved in a DDoS attack differs significantly from the typical distribution of customers for web services, traffic shapers and policers can be used in DDoS mitigation. In the past, software-based middleboxes, like traffic shapers, easily became overloaded and therefore a vulnerability for DDoS attacks. Although recent advances in network stack design on commodity hardware increased the performance, the software on top of the network stack also needs to provide adequate throughput and scalability regarding the number of limited subnets. Therefore, we build a high-performance and scalable traffic policer called MoonPol and evaluated it in a DDoS mitigation scenario. MoonPol runs on any commodity hardware, takes advantage of the underlying framework, DPDK, and combines it with appropriate algorithms and data structures. Data structures for efficient lookups are implemented together with the token bucket algorithm to police a traffic of fine-grained IP address ranges. Benchmarking results show that the single core throughput of the policer running on a 3.2 GHz CPU, is 6.5 Mpps with limiting 1 Million subnets, i.e., 492 CPU cycles per packet. With 250K subnets of all countries in the world, the throughput is 6.66 Mpps.
流量监管是通过流量整形等方法确保网络流量符合其策略的过程。由于DDoS攻击中涉及的源的分布与web服务的典型客户分布有很大不同,因此可以在DDoS缓解中使用流量塑造器和策略。在过去,基于软件的中间件,比如流量整形器,很容易过载,因此成为DDoS攻击的一个漏洞。尽管商用硬件上网络堆栈设计的最新进展提高了性能,但网络堆栈之上的软件还需要提供足够的吞吐量和可伸缩性,以应对有限子网的数量。因此,我们构建了一个名为MoonPol的高性能可扩展流量管理器,并在DDoS缓解场景中对其进行了评估。MoonPol可以在任何商用硬件上运行,利用底层框架DPDK,并将其与适当的算法和数据结构相结合。有效查找的数据结构与令牌桶算法一起实现,以监督细粒度IP地址范围的流量。基准测试结果显示,在3.2 GHz CPU上运行的策略的单核吞吐量为6.5 Mpps,限制了100万个子网,即每个数据包492个CPU周期。25k子网覆盖全球所有国家,吞吐量为6.66 Mpps。

In this paper, we present the functional design and experimental validation of network coding technology over hybrid networks including satellite links. We first describe our design framework based on a holistic modelling of (overlay) heterogeneous networking satellite scenarios. We then define different types of logical nodes depending on their encoding, re-encoding and decoding functionalities and whether or not the satellite (overlay) application designer has control over them. Nodes are assumed strategically chosen to recode, which may result in a small number of re-encoding nodes that suffice to optimize selected performance metrics. Our main contribution is a system-oriented functional design of network coding that enables flexible instantiation of different types of network codes via configurable network coding (C-NC) functions. Random or structured NC coefficients can be remotely or locally generated and a packet scheduler can forward packets according to different policies. The choice of coefficients and overall NC scheme depend on the SATCOM-specific performance target, namely delay or bandwidth constraints. Here, we present a preliminary design and experimental testebed validation for the case of delay constrained transmission. Our results show the practical benefits of re-encoding and performance tradeoffs of different network coding schemes. In particular, our results show the good structural properties and delay-reliability tradeoffs of our novel proposal of structured network codes using Pascal matrices due to the regenerative properties of the coding coefficients.
在本文中,我们提出了包含卫星链路的混合网络的网络编码技术的功能设计和实验验证。我们首先描述了基于(覆盖)异构网络卫星场景的整体建模的设计框架。然后,我们根据它们的编码、重新编码和解码功能以及卫星(覆盖)应用程序设计人员是否对它们进行控制来定义不同类型的逻辑节点。假设有策略地选择节点进行重新编码,这可能导致少量的重新编码节点足以优化所选的性能指标。我们的主要贡献是网络编码的面向系统的功能设计,它可以通过可配置网络编码(C-NC)功能灵活地实例化不同类型的网络代码。随机或结构化NC系数可以远程或本地生成,数据包调度程序可以根据不同的策略转发数据包。系数和整体NC方案的选择取决于satcom特定的性能目标,即延迟或带宽约束。在这里,我们提出了延迟约束传输情况下的初步设计和实验测试台验证。我们的结果显示了重新编码的实际好处和不同网络编码方案的性能权衡。特别是,我们的结果表明,由于编码系数的再生特性,我们使用Pascal矩阵的结构化网络编码的新提议具有良好的结构特性和延迟可靠性权衡。

Cyber-physical security is a major concern for the new generation of trains. In fact, trains are increasingly relying on automation, control and communication technologies in order to improve the efficiency and safety of their services as well as the comfort of passengers. This dependency introduces certainly new vulnerabilities and entry points to the system which exposes the system to new threat scenarios. This paper deals with cyber-physical security aspects of Train Control and Monitoring Systems (TCMSs). We analyse vulnerabilities and characteristics of railway threat landscape including potential threats, threats agents and motivations. We discuss, also, direct impacts and cascading consequences on the whole system as well as the risk generated.

A dual-band frequency reconfigurable monopole antenna is presented in this paper. Reconfiguration of frequency bands is achieved using RF PIN diodes. An already published antenna design is used as a starting point and is then modified to achieve frequency reconfiguration mechanism by incorporating RF PIN diodes. The antenna resonates at center frequency of 2.4 GHz and 4.25 GHz when RF PIN diodes are switched OFF. However, RF PIN diodes ON state resulted in 1.84 and 3.66 GHz frequency bands. The 1.84 and 2.45 GHz bands are controlled by altering the electrical length of inverted L-shaped resonator. Whereas, C-shaped radiator is used to resonate the proposed antenna at 3.66 GHz and 4.56 GHz frequency bands. Overall, the simulation and measurement results showed a good agreement.

This paper discusses design and implementation of SDN Controller application in a Multi-Protocol Label Switching (MPLS) network based on OpenDaylight. In this paper, we first briefly review Traffic Engineering challenges in MPLS networks. We then discuss on how Software-Defined Networking (SDN) could overcome Label Switched Path (LSP) path calculation challenges in MPLS Traffic Engineering. We discuss that a centralized SDN Controller has network-wide visibility thus should become “source of truth” of network state. We discuss that OpenDaylight has capabilities as centralized SDN Controller, however one needs to build application on top of OpenDaylight. An application of SDN Controller based on OpenDaylight is proposed in this paper. To verify the application functionalities, a virtual lab is created to model an MPLS network and an OpenDaylight SDN Controller. A performance measurement of the OpenDaylight SDN Controller is also discussed in this paper.

UNB (Ultra Narrow Band) is one of the technologies dedicated to low-power wide-area communication for IoT, currently exploited by SigFox. The specificity of UNB is the Aloha-type channel access scheme, both asynchronized in time and frequency domain. This randomness can cause partial spectral interference. In this paper, we take advantage of the spatial diversity of multiple base stations to improve the UNB performance, by using selection combining. In the presence of pathloss and spectral randomness of UNB, the channels are considered correlated. A theoretical analysis of outage probability is demonstrated by considering this correlation, for the case of 2 base stations. This methodology of probability computing can be extended to general $K$ BSs. The diversity of multiple receivers is proved to be beneficial in enhancing the performance of UNB networks. This gain is shown to be related to the density of the base stations, as well as the distance between each of them.
超窄带(UNB)是一种专门用于物联网低功耗广域通信的技术,目前由SigFox开发。UNB的特点是aloha型信道接入方案,在时域和频域都是异步的。这种随机性会导致部分光谱干扰。在本文中,我们利用多基站的空间分集,通过选择组合来提高UNB的性能。在UNB存在路径损耗和频谱随机性的情况下,信道被认为是相关的。在考虑这种相关性的情况下,对2个基站的中断概率进行了理论分析。这种概率计算方法可以推广到一般的BSs。事实证明,多接收机的多样性有利于提高UNB网络的性能。这个增益与基站的密度以及每个基站之间的距离有关。

The security threats to mobile application are growing explosively. Mobile app flaws and security defects could open doors for hackers to easily attack mobile apps. Secure software development must be addressed earlier in the development lifecycle rather than fixing the security holes after attacking. Early eliminating against possible security vulnerability will help us increase the security of our software, and militate the consequence of damages of data loss caused by potential malicious attacking. However, many software developer professionals lack the necessary security knowledge and skills at the development stage and Secure Mobile Software Development (SMSD) is not yet well represented in current computing curriculum. In this paper we present a static security analysis approach with open source FindSecurityBugs plugin for Android Studio IDE. We categorized the common mobile vulnerability for developers based on OWASP mobile security recommendations and developed detectors to meet the SMSD needs in industry and education.
移动应用面临的安全威胁呈爆炸式增长。移动应用程序的缺陷和安全缺陷可能为黑客轻易攻击移动应用程序敞开大门。安全软件开发必须在开发生命周期的早期进行处理,而不是在受到攻击后修复安全漏洞。及早消除可能存在的安全漏洞,有助我们提高软件的安全性,并减低因潜在的恶意攻击而造成资料遗失损害的后果。然而,许多软件开发人员在开发阶段缺乏必要的安全知识和技能,安全移动软件开发(SMSD)在当前的计算机课程中尚未得到很好的体现。在本文中,我们提出了一种基于开源FindSecurityBugs插件的静态安全分析方法。我们根据OWASP移动安全建议对开发人员常见的移动漏洞进行了分类,并开发了检测器,以满足工业和教育中的SMSD需求。

A Synthesis Technique for Concentric Rings Array Using Sectional Excitation 一种分段激励的同心环阵合成技术

Many configuration have been used for the array antenna and rectangular or triangular networks have been the most attentive topology. In fact, Synthesis techniques can take the advantage of periodicity of these type of networks. Concentric rings array are a special type of array antennas that are used in tracking radars and acoustic systems. This type of arrays does not have linear periodicity in a plane. Therefore, many methods that are based on the linear periodicity of elements are unable to deal with the difficulty of the calculations. Besides, the number of elements in this type of arrays may be very high or even thousands of elements which makes the synthesis procedure more complicated and time consuming. In this paper, these deficiencies and complexity have been reduced in very great extent by using non-uniform sampling and sectional excitation. In the proposed technique, each array is divided into the smaller sub-arrays making up more control over the symmetric array factor by sectional excitation. This control over array factor makes possible to synthesize asymmetric pattern from such circularly symmetric arrays. The results confirm that using sectional excitation maintains the parameters of the array factor at the desired values and this is done with less time.
阵列天线采用了多种构型,矩形或三角形网络是最受关注的拓扑结构。实际上,综合技术可以利用这类网络的周期性。同心环阵列天线是一种特殊类型的阵列天线,用于跟踪雷达和声学系统。这种类型的阵列在平面上没有线性周期性。因此,许多基于元素线性周期性的方法无法处理计算的困难。此外,这种类型的数组中的元素数量可能非常高,甚至数千个元素,这使得合成过程更加复杂和耗时。本文采用非均匀采样和分段激励的方法,在很大程度上克服了这些缺陷和复杂性。在所提出的技术中,每个阵列被分成更小的子阵列,通过分段激励对对称阵列因子进行更多的控制。这种对阵列因子的控制使得从这种圆对称阵列合成非对称图案成为可能。结果证实,采用分段激励可以使阵列因子的参数保持在期望的值上,而且这样做的时间更短。

The results confirm that using sectional excitation maintains the parameters of the array factor at the desired values and this is done with less time.","PeriodicalId":313846,"journal":{"name":"2018 International Symposium on Networks, Computers and Communications (ISNCC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122704123","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}

In this letter a new decoding algorithm based on the adaptive normalized min-sum algorithm and the joint decoding algorithm is proposed for irregular low density parity check codes in OFDM system. The new proposed algorithm changes the update rule of the normalized min-sum algorithm to improve its performance. Also, instead of having separate horizontal and vertical processing phases in decoding algorithm, the vertical phase is merged with the horizontal phase. The proposed decoder improves the performance in waterfall and error floor regions. The convergence speed of the proposed algorithm is much faster. Therefore, the proposed decoder is able to converge to its final bit error rate in fewer iterations.
针对OFDM系统中不规则低密度奇偶校验码,提出了一种基于自适应归一化最小和算法和联合解码算法的解码算法。该算法改变了归一化最小和算法的更新规则,提高了算法的性能。另外,在解码算法中,不再将水平和垂直处理阶段分开,而是将垂直阶段与水平阶段合并。该解码器提高了瀑布区和错误层区的性能。该算法的收敛速度大大加快。因此,所提出的解码器能够在更少的迭代中收敛到其最终误码率。
