A secure multi-tier authentication scheme in cloud computing environment 云计算环境下安全的多层认证方案
Ashish Singh, Kakali Chatterjee
Day by day users has been adopting remote storage system due to its secure service. But some time it may possible that people comes to know what security policy has been applied in server side. As the result, new security risks and attacks are coming in cloud. So, it is necessary to provide more secured and updated authentication scheme. For any cloud application, in which personal or private information are exchanged, single-tier authentication is not sufficient for authentication. In above situation, multi-tier authentication scheme is much more secured than single-tier authentication scheme. In computing environment, there are various multitier authentication schemes, but they do not provide security against insider attacks and virtualization attacks. In cloud environment, whole authentication control lies in the server side. So, it is hard to trust the third party server in cloud system. This paper proposes a secured and more advanced multi-tier authentication scheme for accessing cloud services.
由于远程存储系统提供安全的服务,越来越多的用户开始采用远程存储系统。但有时人们可能会知道服务器端应用了什么安全策略。因此,新的安全风险和攻击正在云计算中出现。因此,有必要提供更安全、更新的认证方案。对于任何交换个人或私有信息的云应用程序,单层身份验证不足以进行身份验证。在上述情况下,多层认证方案比单层认证方案更安全。在计算环境中,有各种各样的多层身份验证方案,但它们不能提供针对内部攻击和虚拟化攻击的安全性。在云环境中,整个认证控制在服务器端。因此,在云系统中,第三方服务器很难被信任。本文提出了一种安全的、更高级的访问云服务的多层认证方案。

Analysis of six degrees of separation in Facebook using Ant colony optimization 基于蚁群优化的Facebook六度分离分析
E. E. Lawrence, R. Latha
Six degrees of separation is a popular theory that is widely accepted by many people, which states any two people on this world can be connected through an average number of six steps. Though there is no solid scientific evidence that the six degrees of separation theory is true, it remains as an area of interest to social researches. With the advent of digital mapping, the theory can now be tested with social networks, but will the theory of six degrees of separation hold for the virtual world? The link between any two people in a graph with number of hops needs to be identified and that can be done efficiently with the help of Ant colony optimization technique (ACO). As ACO algorithms are proved to be efficient with a broad range of NP hard problems such as the traveling salesman problem (TSP) or the quadratic assignment problem (QAP), and is increasingly gaining interest for solving real life engineering and scientific problems, an attempt has been made in this paper to analyze the six degrees of separation in the popular social network Facebook which has over 1.3 billion active users as of June 2014.
六度分离是一个被许多人广泛接受的流行理论,它认为世界上任何两个人都可以通过平均六个步骤连接起来。虽然没有确凿的科学证据证明六度分离理论是正确的,但它仍然是社会研究的一个感兴趣的领域。随着数字地图的出现,这一理论现在可以在社交网络上得到检验,但六度分隔理论是否适用于虚拟世界?在一个有跳数的图中,任意两个人之间的联系需要被识别,这可以借助蚁群优化技术(ACO)有效地完成。由于蚁群算法被证明在解决旅行推销员问题(TSP)或二次分配问题(QAP)等广泛的NP困难问题上是有效的,并且在解决现实生活中的工程和科学问题方面越来越受到关注,因此本文试图分析流行的社交网络Facebook中的六度分离,截至2014年6月,Facebook拥有超过13亿的活跃用户。

In this paper a novel type of resonant antenna based on asymmetric coplanar wave guide structure has been presented. In the defined geometry bandwidth can be increased by introducing resonator ring in composite right/left handed transmission line model. Efficiency as well as gain of the geometry can be improved by incorporating comb drive type of structure which introduces interdigital capacitors and produces one more resonant frequency. Asymmetric ground plane reduced the dimensions up to 38.5×25 mm. Dual band have been obtained covering impedance bandwidth of (2.34-2.55 GHz), 210 MHz in lower band and (3.2-3.8 GHz),600 MHz in higher band corresponds fractional bandwidth of 8.7% and 16.3%. Antenna geometry is highly efficient showing maximum efficiency of 99% and peak gain up to 4.23dBi. Defined antenna is very suitable for WLAN/LTE applications.

Circuit level technique for mitigating effects of NBTI for wide fan-in domino logic circuits using supply voltage tuning 采用电源电压调谐的宽频扇入多米诺逻辑电路减轻NBTI影响的电路级技术
S. Narang
Transistor ageing has been a major problem as far as nanometre technology is concerned which leads to performance degradation and reliability issues. Ageing in pMOS transistor takes place due to Negative bias temperature instability (NBTI) which is a major threat in reliability as Iscale down the transistor geometries aggressively in our quest for low power and high performance. Overcoming ageing effect requires additional power expense, which in turn aggravates the power and heating problem. I propose an adaptive supply voltage (ASV) scheme as an arguably power efficient approach for variation resilience since it attempts to allocate power resources only where the negative effect of ageing is strong. Upon implementing the proposed approach on a host of domino logic circuits which include Current comparison domino (CCD) Ihave mitigated the rise in delay problem by suitably allocating a supply voltage so that the delay specifications are continuously met even after a lifespan of 10 years of operation at the expense of very low power headroom. Simulations have been performed using the BSIM4v4.7 model & 32 nm predictive technology model in SILVACO EDA tool at a frequency of 2 GHz and nominal supply voltage of 0.9V. The proposed approach has been implemented on 32 bit & 64 bit OR gates and also on 32 bit comparator and the results have been noteworthy.
晶体管老化一直是纳米技术的一个主要问题,它会导致性能下降和可靠性问题。pMOS晶体管的老化是由于负偏置温度不稳定性(NBTI)造成的,这是可靠性的主要威胁,因为我们在追求低功耗和高性能的过程中,积极缩小晶体管的几何形状。克服老化效应需要额外的电力费用,这反过来又加剧了电力和加热问题。我提出了一种自适应供电电压(ASV)方案,作为一种可论证的有效的变化弹性方法,因为它试图仅在老化的负面影响较强的地方分配电力资源。在包括电流比较多米诺(CCD)在内的一系列多米诺逻辑电路上实施所提出的方法后,我通过适当地分配电源电压来减轻延迟问题的增加,以便在以非常低的功率余量为代价的10年运行寿命之后连续满足延迟规格。在SILVACO EDA工具中,采用BSIM4v4.7模型和32 nm预测技术模型,在2 GHz频率和0.9V标称电源电压下进行了仿真。该方法已在32位和64位OR门以及32位比较器上实现,结果值得注意。

Masahiro Aono, K. Takei
We are developing new radio architecture for applying a wireless communication system to controlling and monitoring systems in industrial infrastructure systems. Using polarization angle diversity, we can achieve reliable communication in a non line-of-sight situation. To realize polarization angle diversity, we use a rotating polarized radio wave. When we use polarization angle diversity, we need to control radio frequencies more easily. New software radio architecture create radio frequency in a digital circuit directly. It has a possibility to control a rotating polarization radio wave. And by experiment, I show a result of basic communication test and confirm its functions.

Computer vision based vehicle detection for toll collection system using embedded Linux 基于计算机视觉的收费系统车辆检测
Abhijeet Suryatali, V. B. Dharmadhikari
Many highway toll collection systems have already been developed and are widely used in India. Some of these include Manual toll collection, RF tags, Barcodes, Number plate recognition. All these systems have disadvantages that lead to some errors in the corresponding system. This paper presents a brief review of toll collection systems present in India, their advantages and disadvantages and also aims to design and develop a new efficient toll collection system which will be a good low cost alternative among all other systems. The system is based on Computer Vision vehicle detection using OpenCV library in Embedded Linux platform. The system is designed using Embedded Linux development kit (Raspberry pi). In this system, a camera captures images of vehicles passing through toll booth thus a vehicle is detected through camera. Depending on the area occupied by the vehicle, classification of vehicles as light and heavy is done. Further this information is passed to the Raspberry pi which is having web server set up on it. When raspberry pi comes to know the vehicle, then it access the web server information and according to the type of the vehicle, appropriate toll is charged. This system can also made to count moving vehicles from pre-recorded videos or stored videos by using the same algorithm and procedure that we follow in this paper.
许多高速公路收费系统已经开发出来,并在印度广泛使用。其中包括人工收费,射频标签,条形码,车牌识别。这些系统都有缺点,导致相应的系统存在一些误差。本文简要介绍了印度目前的收费系统,其优点和缺点,并旨在设计和开发一种新的高效收费系统,这将是所有其他系统中一个很好的低成本替代方案。该系统是基于计算机视觉的车辆检测,在嵌入式Linux平台上使用OpenCV库。本系统采用嵌入式Linux开发工具(树莓派)进行设计。在该系统中,摄像机捕捉通过收费站的车辆图像,从而通过摄像机检测车辆。根据车辆占用的面积,将车辆分为轻型和重型。进一步,这些信息被传递给树莓派,树莓派上设置了web服务器。当树莓派来知道车辆,然后它访问web服务器信息,并根据车辆的类型,收取适当的通行费。该系统还可以使用与本文相同的算法和程序,从预录制的视频或存储的视频中对移动车辆进行计数。

Performance based analysis on MALCOM — A software metric 基于MALCOM - A软件度量的性能分析
S. Ganesh, H. Raj
The goal of inventing new software metric for SQA is to analyze the brilliance of the software. Certifying the proposed metric as valid should also be considered as equal to the invention since it describes how good the proposed metric is, how it could be practically implemented, and how useful is it for the technical fraternity and so on. This work is divided into a three-step framework, where in the first step the MALCOM metric is analytically evaluated against a formal list of Weyuker's properties and in the second step we compare MALCOM with its base metric LCOM. The metric complexity is also applied to ANOVA test to analyze the complexity variance in the third step. The results have proven that the metric is valid and satisfies all the necessary conditions of the framework.

Performance evaluation of high efficiency thermoelectric SIMO converter 高效热电SIMO变换器的性能评价
S. Jahan, S. Rajan, T. Rakesh, Assistant Professor
In the present scenario, the modern microelectronic devices are demanding supply with multiple voltages from a power-efficient and miniaturized platform. Unfortunately, the power inductors used in magnetic-based switching converters are bulky and difficult to integrate. The aim of this paper is to develop Single-Input Multiple-Output (SIMO) converter for Thermoelectric Generator (TEG) which is used as the source for supplying the load. The SIMO converter is used to boost the low input voltage of TEG to a middle voltage and high voltage with the help of the coupled-inductor. The middle and high voltage output terminals can be used for supplying power to power sources like batteries. The converter uses only one switch to obtain the various output voltages of different levels which is the main objective of this study. This study is carried out by PI controller and MPPT techniques. The MPPT technique used for this study is Incremental Conductance. The proposed SIMO converter has been modelled and simulated using PSIM software for obtaining higher efficiency. The conversion efficiency of about 96.5% can be achieved and has been reported in this paper.
在目前的情况下,现代微电子设备要求从一个节能和小型化的平台上提供多个电压。不幸的是,在基于磁的开关变换器中使用的功率电感体积庞大,难以集成。本文的目的是研制用于热电发电机(TEG)的单输入多输出(SIMO)变换器,该变换器作为热电发电机(TEG)的电源供电。SIMO变换器利用耦合电感将TEG的低输入电压升压为中压和高压。中高压输出端子可用于向蓄电池等电源供电。该变换器仅使用一个开关即可获得不同电平的各种输出电压,这是本研究的主要目的。本研究采用PI控制器和MPPT技术进行。本研究中使用的MPPT技术是增量电导。为了获得更高的效率,采用PSIM软件对所提出的SIMO转换器进行了建模和仿真。可达到96.5%左右的转换效率,并已在本文中报道。

Estimation of the reactive power of corrupted waveforms using the DWT 用小波变换估计损坏波形的无功功率
M. Vijayakumari, D. Sundararajan
In recent times, due to the increased use of the reactive power, it is important to bill the electrical power consumption based on both the active and reactive power components. Reactive power is a very significant factor in electric power systems since it affects the efficiency of these systems. For this reason, the measurement of reactive energy is also important. Several methods are used to measure reactive power. Reactive energy meters provide accurate measurement only if the input is fundamental, because meters are constructed for operating under sinusoidal conditions. Due to the widespread use of nonlinear loads and natural disturbances such as lightning, the power quality of the waveforms is considerably deteriorated. As the corrupted waveforms are composed of nonstationary components also, in order to estimate the true reactive power of the power system fundamental component, a time-frequency analysis is required. Therefore, in this paper, a DWT based algorithm is proposed to effectively estimate the reactive power component of the power system.
近年来,由于无功功率的使用增加,根据有功功率和无功功率分量对电力消耗进行计费是很重要的。无功功率是电力系统中一个非常重要的因素,因为它影响着电力系统的效率。因此,无功能的测量也很重要。有几种测量无功功率的方法。无功电能表只有在输入是基波的情况下才能提供准确的测量,因为电能表是在正弦条件下运行的。由于非线性负载和雷电等自然干扰的广泛使用,波形的电能质量大大恶化。由于损坏波形也由非平稳分量组成,为了估计电力系统基本分量的真实无功功率,需要进行时频分析。为此,本文提出了一种基于小波变换的有效估计电力系统无功分量的算法。

Reactive power is a very significant factor in electric power systems since it affects the efficiency of these systems. For this reason, the measurement of reactive energy is also important. Several methods are used to measure reactive power. Reactive energy meters provide accurate measurement only if the input is fundamental, because meters are constructed for operating under sinusoidal conditions. Due to the widespread use of nonlinear loads and natural disturbances such as lightning, the power quality of the waveforms is considerably deteriorated. As the corrupted waveforms are composed of nonstationary components also, in order to estimate the true reactive power of the power system fundamental component, a time-frequency analysis is required. Therefore, in this paper, a DWT based algorithm is proposed to effectively estimate the reactive power component of the power system.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"2 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87663303","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}

Vehicular Ad-Hoc Network (VANET) [1] which is a sub-type of the mobile ad-hoc networks provides wireless communication between the vehicles and to the Road Side Units (RSU) [2]. In VANET, the communication between the vehicles is used for various purposes like safety, comfort and entertainment. We use the vehicles as the portable nodes to create the mobile network. The VANET uses all the vehicles in the nearby distance as a wireless router or node to form a network. The vehicles can dynamically come in or drop out of the network as they move. The working of the VANET depends on how the routing of data is done in the network. In the recent years, the number of accidents has been increased to a greater count. In order to eradicate this, the implementation of VANET technology is being used in various modes of transportation. Even though VANET has been proposed to be a successful network model, it has some issues to overcome. The most major issues are the connectivity and the signal fading issue. We can overcome some of the issues in VANET by using the Artificial Bee Colony Algorithm (ABC) [3]. The proposed use of the algorithm in VANET may resolve some of the issues effectively.
车辆自组网(Vehicular Ad-Hoc Network, VANET)[1]是移动自组网的一个子类型,提供车辆与路旁单元(Road Side Units, RSU)之间的无线通信[2]。在VANET中,车辆之间的通信用于各种目的,如安全,舒适和娱乐。我们使用车辆作为便携式节点来创建移动网络。VANET使用附近的所有车辆作为无线路由器或节点形成网络。车辆可以在行驶过程中动态地进入或退出网络。VANET的工作取决于网络中的数据路由是如何完成的。近年来,事故的数量已经增加到一个更大的数字。为了消除这种情况,VANET技术的实施正在各种运输方式中使用。尽管VANET已被认为是一个成功的网络模型,但它仍有一些问题需要克服。最主要的问题是连通性和信号衰落问题。我们可以通过使用人工蜂群算法(ABC)来克服VANET中的一些问题[3]。在VANET中使用该算法可以有效地解决一些问题。
