This book was released on 2007 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Internet has become increasingly popular due to anywhere anytime access feature. The Internet architecture was designed underlying the existing of the end-to-end path connection. The promise of wireless Internet networks is to provide roaming users connectivity anywhere anytime. However, quality of service (QoS) is still an open issue in wireless networks, which are characterized by possible intermittent connectivity and large transmission delays, due to user mobility, sparse mobile node distribution, link failures (because of hostile propagation medium), and/or other high-priority traffc. In this thesis, a credit-based user authentication scheme is proposed for delay tolerant mobile wireless networks. The proposed authentication scheme isolates the uncertain network condition in the high delay wireless backhaul with high error rate, and accelerates the overall authentication process when the mobile terminal roams in the visited network. Furthermore, an analytical study of overall network performance is presented for the authentication scheme in terms of authentication cost and delay. Simulation results demonstrate that the proposed credit-based authentication scheme reduces the overall real time transaction cost and delay for delay tolerant mobile wireless networks.

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 Dynamic Group based Authentication in Wireless Networks written by Huy Hoang Ngo and published by . This book was released on 2010 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authentication is an important part of any computer network. Authenticating individuals and groups of users and services securely and efficiently is challenging, especially in wireless networks. This is because users and services in wireless networks are vulnerable to attack due to the nature of wireless communication and the limitations of wireless devices. The problem is compounded by the need for authentication processes to also be scalable and flexible. Users and services in wireless networks are not only more dynamic than those of wired networks but also greater in number. Authentication processes also need to be able to employ different authentication protocols so that the requirements of different computer networks can be met. A good authentication model for wireless network users and services thus needs to have four desirable properties: security, efficiency, scalability and flexibility. Existing authentication models do not sufficiently possess these characteristics. This thesis presents a novel authentication model aimed to achieve these four major properties.The proposed authentication model consists of a collection of relationships, a group manager and an authentication controller. In this model, users and services are grouped into user groups and service groups respectively. The collection of relationships of users, services and their groups in this model is defined and classified in order to provide proper authentication for both individuals and groups of users and services. The group manager and the authentication controller are proposed in order to allow authentication with the four desirable properties to be achieved.In order to demonstrate the practical value of the proposed authentication model, an architecture is derived followed by a realization. The derived architecture has two layers: the key management layer and the authentication layer. Group management and authentication key distribution are conducted in the key management layer while authentication verification is performed in the authentication layer.We also propose the use of dynamic key technique and group key management in the authentication model. Membership-oriented group key management, adapted for wireless networks, is used to implement the group manager. A dynamic key generation scheme is proposed to create dynamic key sequences and dynamic keys are used to secure communications in both the key management layer and the authentication layer. In order to perform authentication verification, two authentication protocols (ticket-based and request-based) are proposed for the authentication verification of both individuals and groups of users and services and their merits are analysed.Our analysis and evaluation show that the application of the dynamic key scheme and group key management enable security and efficiency properties for authentication. At the same time, the two layers architecture and the proposed authentication model itself achieve flexibility and scalability.In summary, the proposed model, along with the derived architecture and its realisation using dynamic key theory and group key management, offers secure, efficient, scalable and flexible authentication for individuals and groups of users and services in dynamic and large wireless networks.
