Security architecture for the mobile ad hoc networks

Abstract

Security in mobile ad hoc networks (MANETs) has been an actively researched topic for the several years. As opposed to wired networks, MANETs have dynamic topology, limited resources, limited bandwidth and are usually deployed in emergency scenarios outside, where landscape plays important role. MANETs are susceptible to insider and outsider attacks and bring new security challenges which were not present in the wired networks. The most important difference is that every node in MANET acts as a router and routes traffic throughout the network. Compromising one node can hugely affect network performance. In this paper, we present our security architecture for MANETs which secures important aspects of the network. We bring trust model into the network and nodes are secured by different mechanisms tailored specifically for the use in distributed environment. We use Omnet++for network simulations. Simulations use delays measured on the real hardware and we analyze performance of the network during different data plane and control plane loads

Safe Routing Approach by Identifying and Subsequently Eliminating the Attacks in MANET

“…For the scattered context in mobile ad hoc networks, Filipek and Hudec [15] propose a secure structure based on a PKI, trust model, firewall (MANETs), and intrusion prevention system (IPS). Nodes' L0 through L3 of privileges are defined by their trust level, which can be lowered or removed in response to harmful activity.…”

“…By developing a secure attack detection and recognition that takes into account issues like a safe path to endpoints for transmission of data, negligible node energy usage, and the innovation of protection schemes that really can come to terms with egoistic and harmful attacks on the entire network, the security concerns in MANET can be resolved [10][11][12][13][14][15]. The assault detection mechanism for the MANET has not yet been implemented completely.…”

A Secure Data Dissemination in a DHT-Based Routing Paradigm for Wireless Ad Hoc Network

“…For example, the RSA encryption algorithm is used for authentication service in [17]. Public key algorithms are preferred in WANETs due to their effectiveness in terms of key management, confidentiality, and authentication, as shown in [17,[26][27][28][29]. For example, random predistribution of keys (RPK) [30] would not perform well in our target scenario due to the following reasons: (i) First, the random key predistribution schemes that use symmetric cryptography are found susceptible to the replication attack.…”

“…However, there are various approaches to implementing PKI in WANETs by addressing different concerns. A few examples are [17,23,24,[26][27][28][29][30].…”

“…Filipek and Hudec [27] suggest a secure architecture that is based on a trust model along with PKI, intrusion prevention system (IPS), and firewall for the distributed environment in mobile ad hoc networks (MANETs). Nodes' trust level defines their privileges L0 to L3 that can be reduced or revoked upon malicious behavior.…”
