Quantum Steganography-based Least Significant Bit Algorithm for Confidential Data Communication

This paper explores the quantum steganography-based Least Significant Bit algorithm for steganography, aiming to camouflage a secret image within a cover image for secure internet transmission. Modern communication systems prioritize safeguarding sensitive data during transmission through various channels. Many scientists are actively developing encryption and decryption algorithms, focusing on efficiency to maintain data integrity. However, a contrasting challenge arises from advancements in data loss techniques, rendering these algorithms vulnerable to attacks. In response, steganography has emerged as a field within data security, involving the concealment of sensitive information within communication media. Moreover, the use of qubits and quantum states, such as \(|0\rangle \) and \(|1\rangle \) , in quantum computing introduces complexity to data security. Quantum cryptography, rooted in quantum mechanics, enhances communication security. Secure key exchange is achievable through quantum key distribution protocols, leveraging the concepts of superposition and entanglement. The manipulation of quantum states facilitates data encryption, advancing data security in the quantum era. The primary objective is to fortify data security by adeptly misleading potential cyber threats, focusing on securely delivering vital data to its intended recipients, and ensuring the security of sensitive information. Furthermore, encryption technology aims to stay ahead of potential vulnerabilities by constantly evolving to protect against emerging threats.
