An Optimization Based Anonymous Messaging System for Data Security in Delay Tolerant Network

Abstract

Nowadays, the essential need of the Delay Tolerant Network (DTN) is anonymity and security. The protection of sensitive information is more critical in communication environments. Moreover, anonymous communication plays an important role to enhance the communication of DTN. So in this research work design, a novel Honey Bee-based Anonymous Messaging System (HBAMS) model for enhancing the security and communication in the DTN environment and the developed framework is implemented in MATLAB tool. Additionally, design a message forwarding system for enhancing the performance of delivering messages from the source to the destination. As well, a public key cryptosystem is utilized to encrypt data from the plain text into a ciphertext for enhancing security. Consequently, update the honey bee fitness in the cryptosystem to accurate key generation. To check the reliability of the designed model launch attack in the DTN environment and the attack is identified and neglected using the designed model. The gained performance of the designed model is compared with other existing techniques in terms of delivery rate, overhead, packet drop, delay, and CPU time.
