Preetida Vinayakray-Jani, Sugata Sanyal

TL;DR
This paper proposes a distributed security architecture for MANETs that uses clustering, steganography for inter-cluster security, and cryptography for intra-cluster security to address the challenges of dynamic topology and limited resources.
Contribution
It introduces a novel distributed security framework employing clustering, steganography, and cryptography to enhance MANET security without centralized solutions.
Findings
Cluster-based security architecture improves MANET resilience.
Steganography ensures covert inter-cluster communication.
Cryptography secures intra-cluster data transmission.
Abstract
Mobile Ad hoc Networks (MANETs) are subject to various kinds of attacks. Deploying security mechanisms is difficult due to inherent properties of ad hoc networks, such as the high dynamics of their topology, restricted bandwidth, and limited resources in end device. With such dynamicity in connectivity and limited resources it is not possible to deploy centralized security solution but distribution solution. The paper proposes architectural security concept in distributed manner where network is divided into clusters with one cluster head node each. This cluster head node also act as a router providing proactive hidden routing by using Steganographic methods for inter-cluster security. Besides cipher method is used to provide intra-cluster security. The proposed secure architecture specifies operational view of cluster head as a router that provides trust, anonymity and confidentiality…
