Secure message transmission in mobile ad hoc networks

IOSR Journal of Computer Engineering, 2012

The vision of nomadic computing with its ubiquitous access has stimulated much interest in the Mobile Ad Hoc Networking (MANET) technology. However, its proliferation strongly depends on the availability of security provisions, among other factors. We address the problem of secure and fault-tolerant communication in the presence of adversaries across a multi-hop wireless network with frequently changing topology. To effectively cope with arbitrary malicious disruption of data transmissions, we propose and evaluate the secure message transmission (SMT) protocol and its alternative, the secure single-path (SSP) protocol. Among the salient features of SMT and SSP is their ability to operate solely in an end-to-end manner and without restrictive assumptions on the network trust and security associations. As a result, the protocols are applicable to a wide range of network architectures. We demonstrate that highly reliable communication can be sustained with small delay and small delay variability, even when a substantial portion of the network nodes systematically or intermittently disrupt communication. SMT and SSP robustly detect transmission failures and continuously configure their operation to avoid and tolerate data loss, and to ensure the availability of communication. This is achieved at the expense of moderate transmission and routing overhead, which can be traded off for delay. Overall, the ability of the protocols to mitigate both malicious and benign faults allows fast and reliable data transport even in highly adverse network environments.

An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. The primary goal of such an ad-hoc network routing protocol is correct and efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. LAR is an on-demand protocol who is based on the DSR (Dynamic Source Routing). The Location Aided Routing protocol uses location information to reduce routing overhead of the ad-hoc network! Normally the LAR protocol uses the GPS (Global Positioning System) to get these location information's. With the availability of GPS, the mobile hosts knows there physical location. Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks for commercial uses due to their unique properties. One main challenge in design of these networks is their vulnerability to security attacks. In this paper, we study the threats an ad hoc network faces and the security goals to be achieved. We identify the new challenges and opportunities posed by this new networking environment and explore new approaches to secure its communication. In particular, we take advantage of the inherent redundancy in ad hoc networks-multiple routes between nodes to defend routing against denial of service attacks.

The use of communication security protocols originally developed for wire line and WiFi networks can also place a heavy burden on the limited network resources of a MANET. The framework is designed to allow existing network and routing protocols to perform their functions, whilst providing node authentication, access control, and communication security mechanisms.Simulation results comparing SUPERMAN with IPsec, SAODV and SOLSR are provided to demonstrate the proposed frameworks suitability for wireless communication security. It provide secure transmission of data at the time the hackers hit the process received only empty data. This paper presents a novel security framework for MANETs, SUPERMAN. To overcome the traffic issues, delay of transmission nodes and protect from attackers.The data transmission in secure path.

Multipath routing minimizes the consequences of security attacks deriving from collaborating malicious nodes in MANET, by maximizing the number of nodes that an adversary must compromise in order to take control of the communication. In this paper, we identify several attacks that render multipath routing protocols more vulnerable than it is expected, to collaborating malicious nodes. We propose a novel on-demand multipath routing protocol, the Secure Multipath Routing protocol (SecMR) and we analyze its security properties. The SecMR protocol can be easily integrated in a wide range of on-demand routing protocols, such as DSR and AODV.

Mobile ad hoc network security is a new area for research that it has been faced many difficulties to implement. These difficulties are due to the absence of central authentication server, the dynamically movement of the nodes (mobility), limited capacity of the wireless medium and the various types of vulnerability attacks. All these factor combine to make mobile ad hoc a great challenge to the researcher. Mobile ad hoc has been used in different applications networks range from military operations and emergency disaster relief to community networking and interaction among meeting attendees or students during a lecture. In these and other ad hoc networking applications, security in the routing protocol is necessary to protect against malicious attacks as well as in data transmission. The goal of mobile ad hoc security is to safeguard the nodes' operation and ensure the availability of communication in spite of adversary nodes. The node operations can be divided into two phases. The first phase is to discover the route (s) path. The second phase is to forward the data on the available discovered routes. Both stages need to protect from attacks; so many protocols have been proposed to secure the routing and data forwarding. This is a review study to mobile ad hoc protocols for securing routing as well as protocols for securing packets forwarding. Furthermore, it will present the characteristics and the limitations for each protocol and attributes.

Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. This paper analyzes security challenges in ad hoc networks and summarizes key issues that should be solved for achieving the ad hoc security. It also gives an overview of the current state of solutions on such key issues in Mobile Ad Hoc Networks (MANETs). To develop suitable security solutions for such new environments, we must first understand how MANETs can be attacked. Then we discuss various proactive and reactive solutions proposed for MANETs. We outline secure routing solutions to avoid some attacks against the routing protocols based on cooperation between nodes. Keywords— Security; Routing Protocols; Ad Hoc Networks; Attacks; Secure Routing Protocols.

Mobile ad hoc networks (MANETs) represent collaborative networks formed by mobile nodes without a centralized infrastructure, finding application across diverse domains including military and security-sensitive operations. However, securing the routing process within MANETs poses significant challenges due to the absence of a central authority and the dynamic nature of the network. Existing routing protocols suffer from limitations such as bandwidth consumption and route request delays. In response, this paper introduces the Secure and Energy-efficient Zone-based Multipath Routing Protocol (SEZMRPR) for MANETs. SEZMRPR integrates proactive and reactive approaches while incorporating digital signatures and encryption techniques to ensure message integrity, data confidentiality, and end-to-end authentication at the IP layer. The paper provides a comprehensive design of SEZMRPR, assesses its resilience against security attacks, and evaluates its performance through simulations. Results demonstrate SEZMRPR's robustness against security threats, its efficient security performance with acceptable overhead, and its applicability in securing MANETs for military and security-sensitive operations. SEZMRPR, in conjunction with existing security measures, establishes a reliable framework for ensuring secure operations in ad hoc networks. Future enhancements may focus on optimizing performance, scalability, energy efficiency, and addressing quality of service requirements to further refine the protocol.

An ad hoc network is a highly dynamic routing network cooperated by a set of wireless mobile nodes without any assistance of centralized access point. ARIADNE is a well-known secure on-demand ad hoc network routing protocol. After finishing the Route Discovery protocol, it just finds one route for the source and the destination nodes. However, the intermediate nodes can't use that route to transmitting data for themselves. For reducing the Route Discovery broadcast packets and reusing the valid route for increasing the packet delivery ratio, we present a new secure on-demand routing protocol based on ARIADNE, called I-ARIADNE. We design the authentication mechanism for the intermediate nodes to verify the route information and reuse it for another route discovery request. Such design can reduce the broadcast packets. Later, they can use that route for transmitting data to other nodes on it. From simulation results, by using our protocol the performance of the entire network environment will be enhanced.

In this paper we study the routing security issues of MANETs, we propose an algorithm to detect malicious nodes based on intelligent water drops algorithm and examine "routing modification attack" problem that can easily be exploited against the MANETs. We also propose a solution for this problem and examine security issues related to proactive routing protocols for MANETs. This could be achieved by adding some extensions to secure routing. These extensions include integrity which means that the message will not change along the route and authentication which means that the sender is the one who introduces himself. This protection is provided by a hash chain and authentication by digital signature which both added to all control massages. We obtained acceptable results depending on the performance of metrics(end-to-end delay and network load). The difference in average of end-to-end delay when using secure protocol is very small and the average of network load is also very small.
