This paper presents a systematic analysis of insider attacks against mobile ad-hoc routing protocols, using the Ad-hoc On-Demand Distance Vector (AODV) protocol as an example. It identifies a number of attack goals, and then studies how to achieve these goals through misuses of the routing messages. To facilitate the analysis, it classifies insider attacks into two categories: atomic misuses and compound misuses. Atomic misuses are performed by manipulating a single routing message, which cannot be further divided; compound misuses are composed of combinations of atomic misuses and possibly normal uses of the routing protocol. The analysis results in this paper reveal several classes of insider attacks, including route disruption, route invasion, node isolation, and resource consumption. Finally, this paper presents simulation results that validate and demonstrate the impact of these attacks.

Abstract—In this work, we study robustness of DTN routing in the absence of authentication. We identify conditions for an attack to be effective and present an attack based on a combination of targeted flooding and acknowledgement counterfeiting that is highly effective even with only a small number of attackers. Simulation results show that delivery ratio decrease by 30 % to 50 % using only 2 attackers for the two mobility patterns studied (Haggle and DieselNet). We observe that minimum hop count for packet delivery has a strong influence on the robustness of the DTN routing protocols. Generally, attacks become increasingly effective when the minimum hop count required increases. Further, use of global routing metadata in the routing protocol also increases attack effectiveness. Our study provides insights to the robustness of routing attacks in different DTNs settings and can be useful to DTN designers who want to choose the appropriate level of security that is needed for their respective scenarios.

As threats on the Internet become increasingly sophisticated, we now recognize the value in controlling the routing of data in a manner that ensures security. However, few technical means for achieving this goal exist. In this paper we propose and design a system that allows users to specify regions of the Internet they wish their data to avoid. Using our system, data will either arrive at the destination along a path that avoids the specified regions, or no avoiding path exists. Beyond the design, we discuss the deployment, performance and security issues of this system, along with alternative approaches that could be used.

In this article we present a survey of secure ad hoc routing protocols for wireless networks. Ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. Attacks on ad hoc network routing protocols disrupt network performance and reliability with there solution. We briefly present the most popular protocols that follow the table-driven and the source-initiated on-demand approaches. The comparison between the proposed solutions and parameters of ad hoc network shows the performance according to secure protocols. We discuss in this paper routing protocol and challenges and also discuss authentication in ad hoc network.

Abstract — A self-protection technique is suggested for adhoc network fall short of the objective of data privacy, data integrity, and authentication. Various security standards such as IEEE 802.11i, WPA, IEEE 802.1X were suggested to enhance the security issues in 802.11.Despite their efficiency, these standards does not provide any security approach for monitoring of these authentication in a distributed architecture. For the efficient monitoring of the authentication issue in adhoc network, in this paper we present a self monitored security approach for selfmonitoring of key authentication for security protocol in adhoc networks. The processing overhead for the suggested approach is evaluated for a threshold based cryptographic approach.

The outgrowth of the Ad Hoc networking technology urge self-organized wireless interconnection of devices that would either extend or operate in contrive by mutual agreement with the wired networking infrastructure or, possibly, evolve to autonomous networks. In either case, the a rapid increase in number of Ad Hoc based applications depends on a large number of factors, with the trait of deserving trust and confidence being one of the primary challenges to be met. Contempt the existence of well-known security mechanisms, additional vulnerabilities and features to the point to this new networking paradigm might render such traditional solutions inapplicable. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, especially due to the demand of cooperative network operation, since any node may limit the routing protocol functionality by interrupting or breakup the route discovery process. This survey paper discusses the past and most resent research carried out in “Ad hoc network’s routing security” Keywords: Ad hoc networks, Attcks, Routing, Security.

Mobile Ad hoc Networks (MANET) has become an exciting and important technology in recent years because of the rapid proliferation of wireless devices. A mobile adhoc network (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links- the union of which form an arbitrary topology. Secured ad hoc routing protocols are a necessity for securing the routing of data. To have security in the routing, one should sacrifice the performance of the data transmission. This shows that in the secure routing protocols, the usage of security techniques like digital signatures, authentications and hash chains have major impacts on the performance since it will use more processing power and time. Secure routing protocols available today (such as SAODV) still need further optimizations to minimize the processing overhead, delays and to maximize the routing throughputs.
