The Forensic Analysis of a False Digital Alibi 虚假数字不在场证明的法医分析
Aniello Castiglione, G. Cattaneo, G. Maio, A. D. Santis, Gerardo Costabile, M. Epifani
In recent years the relevance of digital evidence in Courts disputes is growing up and many cases have been solved thanks to digital traces that addressed investigations on the right way. Actually in some cases digital evidence represented the only proof of the innocence of the accused. In such a case this information constitutes a digital alibi. It usually consists of a set of local and Internet activities performed through a digital device. It has been recently shown how it is possible to setup a common PC in order to produce digital evidence in an automatic and systematic manner. Such traces are indistinguishable upon a forensic post-mortem analysis from those left by human activity, thus being exploitable to forge a digital alibi. In this paper we verify the undetectability of a false digital alibi by setting up a challenge. An alibi maker team set up a script which simulated some human activities as well as a procedure to remove all the traces of the automation including itself. The verification team received the script and executed it on its own PCs. The verification team could perform not only a usual post-mortem analysis but also a deeper forensic analysis. Indeed, they knew all the details of the script and the original state of the PC before running it. The verification confirmed that a well-constructed false digital alibi is indistinguishable from an alibi based on human activities.
近年来,数字证据在法院纠纷中的相关性越来越大,许多案件的解决都得益于数字痕迹,这些痕迹使调查走上了正确的道路。实际上,在某些案件中,数字证据是证明被告无罪的唯一证据。在这种情况下,这些信息构成了数字不在场证明。它通常由一组通过数字设备执行的本地和互联网活动组成。最近有研究表明,如何能够设置一台普通的个人电脑,以便以自动和系统的方式产生数字证据。在法医的死后分析中,这些痕迹与人类活动留下的痕迹无法区分,因此可以用来伪造数字不在场证明。在本文中,我们通过设置挑战来验证虚假数字不在场证明的不可检测性。一个不在场证明制作团队设置了一个脚本,模拟了一些人类活动,以及一个程序,以消除所有自动化的痕迹,包括它自己。验证小组收到脚本并在自己的pc上执行。核查小组不仅可以进行通常的验尸分析,还可以进行更深入的法医分析。事实上,在运行脚本之前,他们知道脚本的所有细节和PC的原始状态。验证证实,精心构建的虚假数字不在场证明与基于人类活动的不在场证明无法区分。

A Sparse Clustering Model of Wireless Communication Networks 无线通信网络的稀疏聚类模型
Wei-Shuo Li, Chun-Wei Tsai, Jong-Hyouk Lee, W. Hsieh
This paper gives results on the use of stochastic geometry with small cluster for the performance analysis of large wireless networks. The aim is to present a generalization of the assertion that a point process on a wireless communication network significantly depends on the links. In real world graph constructions, the decision on whether to connect two nearby points depends not only on the distance between the nearby points but also on the interaction between them. Motivated by the attempt to unify systematic development and application in modeling real world networks, we propose a new model, called related point process, to generate a random graph and point process by a two-step procedure: 1) the generation of a point process, and 2) the application of a kernel family to each edge to produce sub graphs. It is an alternative approach to specifying a structure of a small cluster in a wireless communication network. We also consider some properties of the model, showing, for example, the degree distribution by using a probability generating functional and giving some asymptotic analysis of the sub graph count. In particular, although our main concern is the power law distribution, we also take into account cases where the distribution model is arbitrary.
本文给出了小簇随机几何在大型无线网络性能分析中的应用结果。目的是提出一种概括的断言,即无线通信网络上的点过程明显依赖于链路。在现实世界的图构造中,是否连接两个邻近点的决定不仅取决于邻近点之间的距离,还取决于它们之间的相互作用。为了将系统的发展和应用统一到现实世界的网络建模中,我们提出了一种新的模型,称为相关点过程,通过两个步骤来生成随机图和点过程:1)生成一个点过程,2)在每个边上应用核族来生成子图。它是在无线通信网络中指定小型集群结构的一种替代方法。我们还考虑了模型的一些性质,例如,用概率生成函数表示度分布,并给出了子图计数的一些渐近分析。特别是,虽然我们主要关注的是幂律分布,但我们也考虑到分布模型是任意的情况。

Participatory Sensing in Environmental Monitoring -- Experiences 环境监测中的参与式感知——经验
Ville Kotovirta, T. Toivanen, Renne Tergujeff, Markku Huttunen
In this paper we describe our experiences in applying the concept of participatory sensing to environmental monitoring. We have run pilot trials for air quality, water quality and plant disease monitoring. In these pilots, users have reported their personal observations or measurements of various environmental phenomena, using special location-based applications in their mobile phones. We found a relevant correlation between algae observations by untrained citizens and by professionals, which supports the feasibility of participatory sensing as a complementary information source for algae monitoring. One key issue in collecting useful participatory datasets is managing to motivate people for acting as mobile environmental sensors. Other important issues discussed in the paper include privacy preservation and reliability of user observations.
在本文中,我们描述了我们将参与式感知概念应用于环境监测的经验。我们在空气质量、水质和植物病害监测方面进行了试点。在这些试点项目中,用户可以使用手机中的特殊定位应用程序,报告他们对各种环境现象的个人观察或测量结果。我们发现未经培训的公民和专业人员的藻类观测之间存在相关关系,这支持了参与式传感作为藻类监测补充信息源的可行性。收集有用的参与性数据集的一个关键问题是如何激励人们充当移动环境传感器。本文讨论的其他重要问题包括隐私保护和用户观察的可靠性。

G. Acampora, V. Loia, A. Vitiello
This paper introduces a proposal for a smart environment capable of deploying enhanced services by using a synergic approach based on Adaptive Neuro-Fuzzy Inference System (ANFIS) and Fuzzy Markup Language (FML). In detail, this approach realizes a long-life learning strategy able to generate context-aware services and actualize them through abstraction techniques in order to maximize the users' comfort and hardware interoperability level. As will be shown in experimental results, where a usability study has been performed, the proposed approach is capable of anticipating user's requirements by automatically generating the most suitable collection of interoperable services for improving users' comfort.

Implementation of the EXI Schema on Wireless Sensor Nodes Using Contiki 基于Contiki的无线传感器节点EXI架构的实现
D. Caputo, L. Mainetti, L. Patrono, A. Vilei
The current trend in Wireless Sensor Networks (WSN) is to use the Internet Protocol (IP) and open standards to achieve native connectivity between smart objects and the Internet, contributing to consolidate the Internet of Things (IoT). Emerging standards such as 6LoWPAN/IPv6 and CoRE/CoAP will play a very important role in a Restful Web of Things, where each node has its own IPv6 address and is able to provide information and control about itself. Data exchanging in Machine To Machine (M2M) applications and communication with Web services require the use of structured data. XML is a possible solution, but its verbosity is not suitable for a WSN (e.g. based on IEEE 802.15.4) characterized by limited packet size. This paper investigates the benefits of Efficient XML Interchange (EXI) in a real scenario, considering sensor nodes running on the Contiki RTOS. For this purpose, the authors have implemented an extremely lightweight version of EXI for Contiki running on application boards with just 8 Kbyte RAM memory.
无线传感器网络(WSN)目前的发展趋势是利用互联网协议(IP)和开放标准实现智能对象与互联网之间的本地连接,为巩固物联网(IoT)做出贡献。诸如6LoWPAN/IPv6和CoRE/CoAP等新兴标准将在Restful Web of Things中扮演非常重要的角色,其中每个节点都有自己的IPv6地址,并且能够提供有关自身的信息和控制。机器对机器(M2M)应用程序中的数据交换以及与Web服务的通信需要使用结构化数据。XML是一种可能的解决方案,但它的冗长性不适合数据包大小有限的WSN(例如基于IEEE 802.15.4的WSN)。本文以运行在Contiki RTOS上的传感器节点为例,在实际场景中研究了高效XML交换(EXI)的好处。为此,作者为Contiki实现了一个非常轻量级的EXI版本,它运行在只有8kbyte RAM内存的应用程序板上。

The Digital Profiling Techniques Applied to the Analysis of a GPS Navigation Device 数字剖面技术在GPS导航设备分析中的应用
Clara Maria Colombini, Antonio Colella, Aniello Castiglione, Vincenzo Scognamiglio
The development of modern technology has led to an evolution in the role of satellite navigation devices that are being transformed into real ``digital diaries'' of those who use them. The software that nowadays is implemented in such devices offers a high level of customization, allowing to store a large amount of data that contains lots of information on user habits. The techniques of Digital Profiling, applied to data stored in a satellite navigation system and in particular on GPS navigators, allow to obtain a range of information that may be useful in conducting an investigation. Those information are, for example, the routes, the favorites, the starting point, and, in more advanced models, the dates of trips, travel times, etc. Such evidence may lead to the delineation of the behavioral profiles of users who have used it. This paper presents the application of Digital Profiling techniques to data taken from a GPS car navigation system.

A Simplified Wiener-Based SIC ICI Cancellation Scheme for OFDM Systems over Time-Varying Channels 一种简化的基于wiener的时变信道OFDM系统SIC ICI对消方案
Yung-Cheng Yao, Ying-Chih Kuo, J. Wen
The sub carriers of orthogonal frequency division multiplexing (OFDM) systems may fail to keep orthogonal to each other under time-varying channels. The loss of orthogonality between the sub carriers will degrade the system performance, and this effect is named inter carrier interference (ICI). A Wiener-based successive interference cancellation (SIC) scheme has been proposed to detect the OFDM signals. It provides good ICI cancellation performance, however, it suffers large computation complexity. In this paper, a modified Wiener-based SIC scheme is proposed to reduce the computation complexity. Simulation results show that the performance of the modified Wiener-based SIC scheme has little degradation as compared to Wiener-based SIC scheme, while its computation complexity can be dramatically reduced.
正交频分复用(OFDM)系统的子载波在时变信道条件下可能无法保持彼此正交。子载波之间的正交性的丧失会降低系统的性能,这种影响被称为载波间干扰(ICI)。提出了一种基于维纳的连续干扰抵消(SIC)方法来检测OFDM信号。它提供了良好的ICI对消性能,但其计算复杂度较大。本文提出了一种改进的基于wiener的SIC方案来降低计算复杂度。仿真结果表明,改进后的基于维纳的SIC方案与基于维纳的SIC方案相比,性能几乎没有下降,但其计算复杂度可以显著降低。

An Analytic Goodput Model for TCP Incast TCP铸模的解析Goodput模型
Zhenqian Feng, Bing Bai, Bao-kang Zhao, Jinshu Su
TCP In cast good put collapse, as a practical problem found in cluster-based storage networks and data center networks, attracts increasing attentions recently. This paper proposes a simple good put model of TCP In cast. Compared with previous In cast model, this model has three different properties. First, the TCP slow start process is considered as an essential part rather than a negligible one, since the request sizes are commonly small and most of the transmissions are accomplished in this process. Second, it exploits a simple logic of determining timeout to account for the cumulative effect of increasing packet losses, reflecting almost all the change points of the good put curves. Finally, the correctness of the model is validated through experimental results instead of simulations.
TCP在cast good put collapse中出现的实际问题,在基于集群的存储网络和数据中心网络中越来越受到关注。本文提出了一个简单的TCP In cast的good put模型。与以往的In cast模型相比,该模型具有三个不同的特性。首先,TCP慢启动过程被认为是一个重要的部分,而不是一个可以忽略的部分,因为请求大小通常很小,并且大多数传输都是在这个过程中完成的。其次,它利用确定超时的简单逻辑来解释数据包丢失增加的累积效应,反映几乎所有的好放曲线的变化点。最后,通过实验而非仿真验证了模型的正确性。

First, the TCP slow start process is considered as an essential part rather than a negligible one, since the request sizes are commonly small and most of the transmissions are accomplished in this process. Second, it exploits a simple logic of determining timeout to account for the cumulative effect of increasing packet losses, reflecting almost all the change points of the good put curves. Finally, the correctness of the model is validated through experimental results instead of simulations.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128265826","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}
