Enhancing the Quantum Communication Channel Using a Novel Quantum Binary Salt Blowfish Strategy

Abstract

Protecting the data from malicious activities in wireless standards is one of the challenging key tasks. Moreover, cryptography plays a vital role in protecting the data in wireless channels. But some of the harmful attacks easily break the crypto algorithm, so quantum cryptography is introduced; it is the transmission of photon also proved better security for the quantum channel than the classical cryptography. So the attack in the quantum channel is difficult, but once if the quantum channel gets attacked by harmful attacks, then preventing them is too difficult. So, to enhance the security of the quantum channel, the current research proposed a novel Binary Salt Blowfish (BSB) for the encryption and decryption process. The aim of this proposed model is to enhance the security in the quantum channel against harmful activities. The proposed model is applied in the BB84 dataset; also, to check the efficiency of the proposed model, the attack like Man In The Middle (MITM) attack and Ciphertext Only Attack (COA) is launched in the quantum channel. But the quantum channel remains secure while in the presence of the attack by an efficient proposed algorithm. Finally, the efficiency of the proposed approach is compared with recent existing works and achieved better results by attaining better confidential as 99% and less error rate as 0.1. Also, it has improved the confidential rate up to 9% than the existing approaches.
