Quantum Cryptography Using Cloud Storage System

Abstract
This paper presents a secure, scalable file transfer and storage model using Quantum Cryptography integrated with Cloud Storage Systems. The solution leverages the principles of Quantum Key Distribution (QKD) to enable an unbreakableencryptionprocess,eliminatingthethreatofman- in-the-middle and brute-force attacks. Unlike traditional cryptographic systems, which rely on computational hardness assumptions, quantum cryptography provides provable security guaranteed by the laws of quantum physics. Files are encrypted using symmetric algorithms with keys distributed through quantum channels. The model also includes secure authentication layers and access control using biometric and OTP-based mechanisms. Integration with cloud platforms ensures data redundancy, availability, and on-demand access for global users. The integration of this model with cloud platforms ensures secure storage and access scalability for enterprise and academic applications.
