Securing Mobile Ad Hoc Networks

Security and Communication Networks, 2010

In this paper, we propose a new architecture based on an efficient trust model and Secure Distributed Clustering Algorithm (SDCA) in order to distribute a certification authority (CA) for ensuring the distribution of certificates in each cluster. We use the combination of a fully self-organized security for trust models like P GP adapted to ad-hoc technology and the clustering algorithm which is based on the use of trust and mobility metrics, in order to select the clusterhead and to establish P KI in each cluster for authentication and exchange of data. Furthermore, we present a new approach: the Dynamic Demilitarized Zone (DDM Z) to protect the CA in each cluster. The principal idea of DDM Z consists in selecting the dispensable nodes, also called registration authorities (RA); these nodes must be confident and located at one-hope from the CA. Their roles are to receive, filter and treat the requests from any unknown node to the CA. With this approach, we can avoid the single point of failure in each cluster. Moreover, we propose a probabilistic model to define the direct connectivity between confident nodes in order to study the resistance degree of the DDM Z against different attacks. In addition, we evaluate the performance of the proposed SDCA and we estimate the robustness and the availability of DDM Z through the simulations. The effects of direct connectivity and transmission range on the stability and security of the network are analysed. The simulation's results confirm that the proposed architecture is scalable, secure and more resistant against attacks. † This work is supported by the ANR "Agence Nationale de la Recherche -France" within the project framework ARA/CLADIS. can communicate with each other by using multihop links to forward traffic from the source to the destination. The nodes' mobility results in a dynamically changing network topology. All these characteristics make MANET original and popular in different application fields such as rescue missions, military operations, etc. However, the characteristics of MANET make it vulnerable to several attacks. In addition, a lack of central administration entity in MANET makes the existing security solutions not applicable to MANET. Hence, providing secure solutions for MANET is a challenge task. The goal of secure solutions is to provide security services,

One of the most important issues for mobile ad-hoc Networks (MANETs) is Security. The feature of MANETs posture both difficulties and openings in accomplishing security objectives, for example, privacy, validation, respectability, accessibility, control of access, and non-repudiation at the end. The techniques of Cryptographic are generally utilized for secure interchanges in wired and remote systems. Most mechanisms of cryptographic, for example, symmetric and asymmetric cryptography, frequently include the utilization of cryptographic keys. Nevertheless, every single cryptographic method will be useless if the management of the key is feeble. The Management of Key is additionally a focal segment in MANET security. The motivation behind key management is to give secure strategies to taking care of cryptographic keying materials.

Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. Unlike the wireline networks, the unique characteristics of mobile ad hoc networks pose a number of nontrivial challenges to security design, such as open peer-to-peer network architecture, shared wireless medium, stringent resource constraints, and highly dynamic network topology. These challenges clearly make a case for building multifence security solutions that achieve both broad protection and desirable network performance. In this article we focus on the fundamental security problem of protecting the multihop network connectivity between mobile nodes in a MANET. We identify the security issues related to this problem, discuss the challenges to security design, and review the state-of-the-art security proposals that protect the MANET link-and network-layer operations of delivering packets over the multihop wireless channel. The complete security solution should span both layers, and encompass all three security components of prevention, detection, and reaction. 1536-1284/04/$20.00 © 2004 IEEE Broadcast [[REP,S,CERTd,Ns,t]Kdt]Kd-]Ka-],CERTa

In this paper we propose a hybrid, trusted and secure DSR-S* protocol with Intrusion Detection System (IDS) as a Network-Layer Security solution to mitigate selective packet dropping by Byzantine nodes in Mobile ad hoc Networks (MANETs). This is a hybrid security solution that assumes no a priori trust between network nodes and makes use of both first-line preventative mechanisms like authentication and encryption; and second-line defensive mechanisms like intrusion detection and reaction systems. Our approach adopts a distributed-probing technique, in which each participating network node carries a valid token that should be renewed before it expires by its one-hop neighbours, which collaboratively monitors it for any possible misbehaviour in packet routing and forwarding services. This should guarantee effective and efficient packet routing and overall MANET security.

Be short of well-defined networks boundaries, shared medium, collaborative services, and dynamic nature, all are representing some of the key characteristics that distinguish mobile ad hoc networks from the conventional ones. Besides, each node is a possible part of the essential support infrastructure, cooperate with each other to make basic communication services available. Forwarding packets or participating in routing process, either of each can directly affect the network security state. Nevertheless, ad hoc networks are suspectable to the same vulnerabilities and prone to the same types of failures as conventional networks. Even though immune-inspired approaches aren't essentially new to the research domain, the percentage of applying immune features in solving security problems fluctuates. In this paper, security approach based on both immunity and multiagent paradigm is presented. Distributability, second response, and self recovery, are the hallmarks of the proposed security model which put a consideration on high nodes mobility.

In recent years Mobile ad-hoc network (MANET) is one of the most promising fields for research and development of wireless network. As the popularity of mobile device and wireless networks significantly increased over the past years, wireless ad-hoc networks has now become one of the most vibrant and active field of communication and networks. Due to severe challenges, the special features of MANET bring this technology great opportunistic together. Owe to the vulnerable nature of the mobile ad hoc network, there are numerous security threats that disturb the development of it. We first analyze the main vulnerabilities in the mobile ad hoc.

Mobile Ad hoc Networks (MANETs) are wireless networks consisted of mobile free nodes that can move anywhere at any time without the need to any fixed infrastructure or any centralized administration. In this category of networks existing nodes must rely on each other to play the role of routers or switches instead of using central ones. The self-organized nature of such environments made MANETs vulnerable against many security threats. As a result, providing security requirements in MANETs is one of the most interesting challenges in such a network. In this group of networks, the use of cryptographic solutions is one of the most interesting security issues. The importance of this scientific area in MANETs is more drastic by considering that mentioned schemes must be lightweight enough to be appropriate for resource constrained platforms in such environment. This paper has tried to represent the position of cryptographic issues in MANETs. Moreover, security issues in mobile Ad hoc networks beside of different classes of public key cryptosystems have been introduced.

An ad hoc network is a collection of nodes that do not need to rely on a predefined infrastructure to keep the network connected. Nodes communicate amongst each other using wireless radios and operate by following a peer-to-peer network model. In this article, we propose a multifold node authentication approach for protecting mobile ad hoc networks. The security requirements for protecting data link and network layers are identified and the design criteria for creating secure ad hoc networks using multiple authentication protocols are analysed. Such protocols, which are based on zero-knowledge and challengeresponse techniques, are presented through proofs and simulation results. a single authority (e.g. a single military unit or a rescue team). With the progress of technology, however, it is possible to deploy MANET for civilian applications as well . Examples include networks of cars and provision of communication facilities in remote areas. In these networks, the nodes do not necessarily belong to a single authority. In addition, these networks could be larger, have a longer lifetime, and they could be completely self-organized, meaning that the network could be managed by the end users.

An ad hoc Network is a new generation of network offering unrestricted mobility without any underlying infrastructure. In this kind of network, all the nodes share the responsibility of network formation and management. This paper proposes a five-layer security architecture for ad hoc networks, that provides self organized distributed security, and authenticated, T Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. The performance evaluation have their place in wireless network research, the current and future applications of the ad hoc networks have forced the research community to look at dependability and security aspects as eavesdropping and jamming. To develop suitable security solutions for such new environments, we must first understand how MANETs can be attacked. This chapter provides a comprehensive survey of attacks against a specific type of target, namely the routing protocols used by MANETs. We introduce the security issues specific to MANETs and present a detailed classification of the attacks/attackers against these complex distributed systems. Then we discuss various proactive and reactive solutions proposed for MANETs. It then addresses the possible solution to protect the security mechanism, which involves availability, integrity, authentication and non repudiation. These securities related issues are well addressed if one can provide methods that are pertinent for authentication, key distribution, and intrusion detection and rerouting in case of Byzantine failure in MANETS. Depending on the application context, a user may desire various security services such as authentication, integrity, non-repudiation, Confidentiality,(KTM) Key and Trust Management and access control.
