Secure Routing and Data Transmission in Mobile Ad Hoc Networks

TL;DR

This paper introduces an ID-based security protocol for MANETs that enhances AODV and TCP by using RSA-based signatures and session keys, preventing ID changes and attacks in dynamic environments.

Contribution

It proposes a novel ID-based security scheme combining RSA signatures and session keys to protect routing and data transmission in MANETs.

Findings

The protocol effectively secures AODV and TCP against attacks.

Performance analysis confirms the scheme's efficiency.

ID consistency prevents malicious ID changes.

Abstract

In this paper, we present an identity (ID) based protocol that secures AODV and TCP so that it can be used in dynamic and attack prone environments of mobile ad hoc networks. The proposed protocol protects AODV using Sequential Aggregate Signatures (SAS) based on RSA. It also generates a session key for each pair of source-destination nodes of a MANET for securing the end-to-end transmitted data. Here each node has an ID which is evaluated from its public key and the messages that are sent are authenticated with a signature/ MAC. The proposed scheme does not allow a node to change its ID throughout the network lifetime. Thus it makes the network secure against attacks that target AODV and TCP in MANET. We present performance analysis to validate our claim.
