Download or read book Social-context Based Routing and Security in Delay Tolerant Networks written by Roy Alan Cabaniss and published by . This book was released on 2013 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Delay Tolerant Networks (DTNs) were originally intended for interplanetary communications and have been applied to a series of difficult environments: wireless sensor networks, unmanned aerial vehicles, and short-range personal communications. There is a class of such environments in which nodes follow semi-predictable social patterns, such as wildlife tracking or personal devices. This work introduces a series of algorithms designed to identify the social patterns present in these environments and apply this data to difficult problems, such as efficient message routing and content distribution. Security is also difficult in a mobile environment. This is especially the case in the event that a large portion of the network is unreliable, or simply unknown. As the network size increases nodes have difficulty in securely distributing keys, especially using low powered nodes with limited keyspace. A series of multi-party security algorithms were designed to securely transmit a message in the event that the sender does not have access to the destinations public key. Messages are routed through a series of nodes, each of which partially decrypts the message. By encrypting for several proxies, the message can only be intercepted if all those nodes have been compromised. Even a highly compromised network has increased security using this algorithm, with a trade-off of reduced delivery ratio and increased delivery time"--Abstract, page iv.

Download or read book Security in Delay Tolerant Networks written by Haojin Zhu and published by . This book was released on 2009 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay- and Disruption-tolerant wireless networks (DTN), or opportunistic networks, represent a class of networks where continuous end-to-end connectivity may not be possible. DTN is a well recognized area in networking research and has attracted extensive attentions from both network designers and application developers. Applications of this emergent communication paradigm are wide ranging and include sensor networks using scheduled intermittent connectivity, vehicular DTNs for dissemination of location-dependent information (e.g., local ads, traffic reports, parking information, etc.), pocket-switched networks to allow humans to communicate without network infrastructure, and underwater acoustic networks with moderate delays and frequent interruptions due to environmental factors, etc. Security is one of the main barriers to wide-scale deployment of DTNs, but has gained little attention so far. On the one hand, similar to traditional mobile ad hoc networks, the open channel and multi-hop transmission have made DTNs vulnerable to various security threats, such as message modification/injection attack or unauthorized access and utilization of DTN resources. On the other hand, the unique security characteristics of DTNs including: long round-trip delay, frequent disconnectivity, fragmentation, opportunistic routing as well as limited computational and storage capability, make the existing security protocols designed for the conventional ad hoc networks unsuitable for DTNs. Therefore, a series of new security protocols are highly desired to meet stringent security and efficiency requirements for securing DTNs. In this research, we focus on three fundamental security issues in DTNs: efficient DTN message (or bundle) authentication, which is a critical security service for DTN security; incentive issue, which targets at stimulating selfish nodes to forward data for others; and certificate revocation issue, which is an important part of public key management and serves the foundation of any DTN security protocols. We have made the following contributions: First of all, the unique "ore-carry-and-forward" transmission characteristic of DTNs implies that bundles from distinct/common senders may opportunistically be buffered at some common intermediate nodes. Such a "buffering" characteristic distinguishes DTN from any other traditional wireless networks, for which intermediate cache is not supported. To exploit such buffering opportunities, we propose an Opportunistic Batch Bundle Authentication Scheme (OBBA) to dramatically reduce the bundle authentication cost by seamlessly integrating identity-based batch signatures and Merkle tree techniques. Secondly, we propose a secure multi-layer credit based incentive scheme to stimulate bundle forwarding cooperation among DTNs nodes. The proposed scheme can be implemented in a fully distributed manner to thwart various attacks without relying on any tamper-proof hardware. In addition, we introduce several efficiency-optimization techniques to improve the overall efficiency by exploiting the unique characteristics of DTNs. Lastly, we propose a storage-efficient public key certificate validation method. Our proposed scheme exploits the opportunistic propagation to transmit Certificate Revocation List (CRL) list while taking advantage of bloom filter technique to reduce the required buffer size. We also discuss how to take advantage of cooperative checking to minimize false positive rate and storage consumption. For each research issue, detailed simulation results in terms of computational time, transmission overhead and power consumption, are given to validate the efficiency and effectiveness of the proposed security solutions.

Download or read book Delay and Disruption Tolerant Networks written by Aloizio Pereira da Silva and published by CRC Press. This book was released on 2018-09-04 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delay- and Disruption Tolerant Networks (DTNs) are networks subject to arbitrarily long-lived disruptions in connectivity and therefore cannot guarantee end-to-end connectivity at all times. Consequently DTNs called for novel core networking protocols since most existing Internet protocols rely on the network’s ability to maintain end-to-end communication between participating nodes. This book presents the fundamental principles that underline DTNs. It explains the state-of-the-art on DTNs, their architecture, protocols, and applications. It also explores DTN’s future technological trends and applications. Its main goal is to serve as a reference for researchers and practitioners.

Book Synopsis Securing Network Resources in Opportunistic and Delay-tolerant Networks by : John Solis
Download or read book Securing Network Resources in Opportunistic and Delay-tolerant Networks written by John Solis and published by . This book was released on 2010 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we investigate security problems of delay- and disruption-tolerant networks operating in challenged environments. In these settings, providing even basic services presents unique challenges due to environmental and infrastructure constraints. One challenge is to establish a private communication channel when peer security credentials are unknown or unobtainable. A second challenge is to secure personal resource contributions from abusive users when public access is uncontrolled. We investigate the above issues while focusing on two application scenarios: rural-area communication networks and ad-hoc personal device networks. First, we consider a method for establishing an initial security context using casual information that links users to well-known entities. Next, we investigate several secure resource management algorithms for controlling abusive users. Finally, we relax authentication requirements of our resource management algorithms to reduce overhead and support fragmentation. We evaluate proposed techniques through simulations and analysis. The main research contributions of this thesis are: 1. Novel Secure Initial Context Establishment Protocol: We suggest a simple technique for achieving secure communication by leveraging casual information to establish an initial security context. This knowledge links users to a more prominent entity whose security credentials are likely to be well-known. We evaluate the proposed technique by analyzing real-world social network data and simulating intra- and inter-region communication scenarios. 2. Resource Management Schemes: To prevent users from sending more personal data and forwarding less peer data we propose and experimentally evaluate a basic technique based on coarse-grained priority classes. User or node authentication can be the basis for constructing priority classes. We use simulations to show the effectiveness of the basic technique for handling abusive users. We also consider three extensions for handling trusted senders who may become abusive. 3. Impact of Fragmentation on Resource Management Schemes: Fragmentation improves message delivery ratios by optimizing limited contact. However, it negates the benefits of resource management when fragments cannot be authenticated. We extend our previous resource management schemes to support fragmentation and reassess their effectiveness. 4. Best-Effort Authentication: Best-effort relaxes full authentication assumptions required by intermediaries in our previous networking scenarios. We propose two techniques for implementing best-effort authentication and investigate their effectiveness in resource management algorithms. Simulations show that this approach is feasible for our target application scenario even when false positive rates are high. xvi.

Book excerpt: Despite the fast pace at which technology is spreading and communication networks are growing, some environments remain a challenge for communication service providers. In areas characterized by intermittent connectivity, long propagation delays, and high interference, networks with strict connectivity requirements do not provide the optimal solution. These limitations increased the interest in developing delay-tolerant networks (DTNs) that can provide the basic means of communication without a strict demand for connectivity, network capacity, or regular mobility patterns of communicating nodes. --A possible application of DTNs is communication in the presence of oppressive governments. We attempt to develop a secure DTN system that enables citizens to communicate securely in an environment where public communication methods, such as mobile networks and the Internet, are intercepted and used by the authorities to monitor civilian activities. --The proposed system is composed of several disconnected zones in which data flows between Private Key Generators (PKGs) and normal nodes. Mobile gateway nodes carry messages between the different zones. We simulate the system using GrooveNet, and describe the effects of different parameters on the overall performance and security of the system.
