QUANTUM KEY DISTRIBUTION FOR ULTRA-SECURE WIRELESS COMMUNICATION

EMERGING TRENDS IN DIGITAL TRANSFORMATION

The Wireless communication networks have been increasing their speed at a fast pace while the data sent over unsecured channels has become a major concern due to security issues. The advancement in cryptography techniques is based mainly on computational hardness, which will be endangered as quantum computing technology advances. Quantum Key Distribution (QKD) is a way to share keys in a secure manner based on quantum mechanics principles, which do not allow any kind of unauthorized access. Here we present a wireless communication framework that is secure in nature and makes use of Quantum Key Distribution along with support from Grover’s quantum search algorithm. In particular, the overall system provides generation, distribution, and verification of keys among communicating partners through both quantum channel and classical communication channel security features. Using Grover’s algorithmize one can make key validation more efficient without much increasing computational need for compromising system performance. This will result in high performance systems. This thesis proposed model covers the basic aspects of the techniques, error correction and key sifters. All this together helps to determine a verifiable secret key implementation as a practicable instrument. The system’s performance is simulated in an assesment based evaluation for system security strength, rate of key generation and resistance to eavesdropping threats .This shows that the Security System provides protection against both Classical as well as Quantum Threats and also guarantees efficiency in their communication. The method proposed above is a scalable and future-ready security solutions for the next generation of wireless networks. It does so by contributing to the fortified communication systems in the quantum era and helping develop an enhanced quantum cryptographic system.

SECURING 6G WIRELESS TRANSMISSION THROUGH QUANTUM KEY DISTRIBUTION INTEGRATED WITH VISIBLE LIGHT COMMUNICATION

Journal of Theoretical and Applied Information Technology

The advent of 6G wireless networks requires strong physical layer security (PLS) measures to guard off ever-changing cyber dangers and guarantee extremely dependable communication. In congested locations, traditional security systems based on radio frequency (RF) encounter challenges such as increased interference, eavesdropping concerns, and spectrum congestion. To tackle these issues, the present research investigates how Visible Light Communication (VLC) might be incorporated into 6G networks to supplement existing methods of improving PLS. Minimizing interference from outside sources during VLC signal transmission, guaranteeing safe key exchange, and finding the optimal location for system performance and security are all significant obstacles. This research presents a new framework Quantum-Enhanced Secure VLC (QES-VLC), which uses adaptive beamforming in conjunction with quantum key distribution (QKD) to improve data security and reduce the probability of interception. This method guarantees a smooth handoff between hybrid VLC-RF networks and restricts illegal access by taking advantage of VLC's inherent directional transmission features. Secure vehicle communications, industrial automation, and smart city infrastructure of the future are all areas where this research could be beneficial. This approach enables ultra-secure, high-speed wireless networks by incorporating VLC into the 6G ecosystem; this improves security without reducing efficiency. An improvement in resilience against eavesdropping is achieved at 99.5%, a decrease in bit error rate to 15.7%, and an increase in secrecy capacity to 98.2%. An extensive simulation analysis is performed using MATLAB to test the suggested approach. The results showed that secure key exchange efficiency improved to 97.3%, while system latency and power consumption are lowered to 28.3% and 18.9%, respectively. In addition, its effectiveness in secure data transfer has been experimentally validated in a real-time VLC experimentation.

Simulation-based modeling of quantum key distribution in a Li-Fi system using free-space optics and polarization modulation

Rajeev Ranjan, Pratham Vinayak Sharma

Abstract With increasing demands for secure high-speed wireless communications, integration of quantum key distribution (QKD) into light fidelity (LiFi) systems is a promising method for boosting data confidentiality in optical wireless networks. The BB84 protocol and Mach–Zehnder modulator (MZM) are utilized with a pump-assisted continuous wave laser at 1,550 nm and polarization control components to encode quantum states onto photons. They are transmitted on free space optical (FSO) links with a length ranging from 2 km to 8 km and received using Avalanche photodiodes (APDs) and optical filters. Performance analysis conducted using bit error rate (BER) and Q-factor analysis. BER maintained at zero across all tested configuration and transmission distance up to 8 km indicating excellent signal integrity and security. A highest Q-factor achieved a maximum of 3,055.9, which ensures signal integrity and low interference noise. The system operates at a simulated data rate of 10 Gbps, suitable for high speed optical wireless communication. Consistently high eye height (∼172,210 units) and stable decision thresholds confirm minimal inter-symbol interference and accurate symbol recognition. And the Poincaré sphere showed even polarization stability for different optical power levels. This work presents a simulation-based implementation of a polarization encoded QKD system over a LiFi-enabled FSO communication channel, aiming to enhance secure optical wireless communication. Calculated based on quantum bit error rate (QBER) and included in the theoretical analysis to demonstrate practical secure throughput.
