Conducting and Optimizing Eclipse Attacks in the Kad Peer-To-Peer Network
Conducting and Optimizing Eclipse Attacks in the Kad Peer-to-Peer Network Michael Kohnen, Mike Leske, and Erwin P. Rathgeb University of Duisburg-Essen, Institute for Experimental Mathematics, Ellernstr. 29, 45326 Essen [email protected], [email protected], [email protected] Abstract. The Kad network is a structured P2P network used for file sharing. Research has proved that Sybil and Eclipse attacks have been possible in it until recently. However, the past attacks are prohibited by newly implemented secu- rity measures in the client applications. We present a new attack concept which overcomes the countermeasures and prove its practicability. Furthermore, we analyze the efficiency of our concept and identify the minimally required re- sources. Keywords: P2P security, Sybil attack, Eclipse attack, Kad. 1 Introduction and Related Work P2P networks form an overlay on top of the internet infrastructure. Nodes in a P2P network interact directly with each other, i.e., no central entity is required (at least in case of structured P2P networks). P2P networks have become increasingly popular mainly because file sharing networks use P2P technology. Several studies have shown that P2P traffic is responsible for a large share of the total internet traffic [1, 2]. While file sharing probably accounts for the largest part of the P2P traffic share, also other P2P applications exist which are widely used, e.g., Skype [3] for VoIP or Joost [4] for IPTV. The P2P paradigm is becoming more and more accepted also for professional and commercial applications (e.g., Microsoft Groove [5]), and therefore, P2P technology is one of the key components of the next generation internet. -
PSP-Auto: a DHT-Based Data Storage and Retrieval System for Automation
PSP-Auto: A DHT-based Data Storage and Retrieval System for Automation Jan Skodzik, Peter Danielis, Vlado Altmann, Eike Bjoern Schweissguth, Dirk Timmermann University of Rostock Institute of Applied Microelectronics and Computer Engineering 18051 Rostock, Germany, Tel./Fax: +49 381 498-7284 / -1187251 Email: [email protected] Abstract—In the field of automation, reliability is a key aspect which utilizes volatile rather than rarely available persistent to enable resilient systems. Especially, in areas with extreme memory as miniature devices often have a low or no memory conditions a reliable monitoring is necessary such as factory, capacity anyway. In the preliminary works [3] and [4], it volcano, or laboratory monitoring. These are environments where devices could be stressed uncommonly high and thus more devices has already been shown that a distributed memory can be could fail in a shorter time period in the worst case. Centralized realized by means of the so-called Peer-to-Peer-based Storage monitoring systems, which work in real-time for security reasons, Platform (PSP). Thereby, network elements of an Internet contain a single point of failure in the form of a central control service provider in the access network were networked to store instance. Additionally, if the central instance fails no data is configuration data. As basis, the decentralized and structured available any more as the central instance usually works as the only data sink in the system. Furthermore, with an increasing P2P protocol Kad has been applied. However, the requirements number of devices this system does not scale well. As the number in automation environments are more demanding than in access of devices and their performance will prospectively increase, a networks as automation environments require tremendously new approach is necessary to handle these large-scale systems. -
A Study of Peer-To-Peer Systems
A Study of Peer-to-Peer Systems JIA, Lu A Thesis Submitted in Partial Fulfilment of the Requirements for the Degree of Master of Philosophy in Information Engineering The Chinese University of Hong Kong August 2009 Abstract of thesis entitled: A Study of Peer-to-Peer Systems Submitted by JIA, Lu for the degree of Master of Philosophy at The Chinese University of Hong Kong in June 2009 Peer-to-peer (P2P) systems have evolved rapidly and become immensely popular in Internet. Users in P2P systems can share resources with each other and in this way the server loading is reduced. P2P systems' good performance and scalability attract a lot of interest in the research community as well as in industry. Yet, P2P systems are very complicated systems. Building a P2P system requires carefully and repeatedly thinking and ex- amining architectural design issues. Instead of setting foot in all aspects of designing a P2P system, this thesis focuses on two things: analyzing reliability and performance of different tracker designs and studying a large-scale P2P file sharing system, Xun- lei. The "tracker" of a P2P system is used to lookup which peers hold (or partially hold) a given object. There are various designs for the tracker function, from a single-server tracker, to DHT- based (distributed hash table) serverless systems. In the first part of this thesis, we classify the different tracker designs, dis- cuss the different considerations for these designs, and provide simple models to evaluate the reliability of these designs. Xunlei is a new proprietary P2P file sharing protocol that has become very popular in China. -

Blockchain, which has a distributed structure, has been widely used in many areas. Especially in the area of smart cities, blockchain technology shows great potential. ,e security issues of blockchain affect the construction of smart cities to varying degrees. With the rapid development of quantum computation, elliptic curves cryptosystems used in blockchain are not secure enough. ,is paper presents a blockchain system based on lattice cipher, which can resist the attack of quantum computation. ,e most challenge is that the size of public keys and signatures used by lattice cryptosystems is typically very large. As a result, each block in a blockchain can only accommodate a small number of transactions. -

However, a shift in the demand for current and future services has led to new requirements on network infrastructure, service orches- tration, and Quality-of-Service (QoS). Services related to, for example, online-gaming, video-streaming, smart cities, smart homes, connected cars, or other Internet-of-Things (IoT) powered use cases are data-intensive and often have real-time and locality require- ments. -

Towards a Basic DHT Service: Analyzing Network Characteristics of a Widely Deployed DHT Konrad Junemann,¨ Philipp Andelfinger, and Hannes Hartenstein Steinbuch Centre for Computing (SCC) Karlsruhe Institute of Technology (KIT), Germany {juenemann, hartenstein}@kit.edu, philipp.andelfi[email protected] Abstract—Distributed Hash Tables (DHTs) prove valuable for DHT-based applications without having to worry about DHT distributed architectures by providing distributed information deployment, running OpenDHT nodes on PlanetLab entailed lookup, routing, and data storage while promising good scala- two disadvantages: first, the DHT did not scale with growing bility and robustness at the same time. From this point of view, a DHT could be seen as a basic service that can be used to numbers of clients as the DHT consisted of a fixed number of build distributed applications. Whereas today no widely deployed (centrally administered) PlanetLab nodes only and clients did and publicly accessible basic DHT service exists and thus DHT- not contribute to the DHT. Second, the OpenDHT nodes had based applications have to deploy their very own DHT networks, to be maintained.

Although the interfaces of typical DHTs used for file sharing are too narrow, a basic DHT service could probably be aging DHTs to replace centralized components within their created by bundling a suitable client implementation with file file sharing networks. Therefore, DHT clients were bundled sharing software.
