Abstract
Quantum computers create new security risks for today's encryption systems. This paper presents an improved version of the Advanced Encryption Standard (AES) that uses quantum technology to strengthen protection. Our approach offers two modes: a fully quantum-based method for maximum security and a hybrid version that works with existing infrastructure. The system generates encryption keys using quantum randomness instead of predictable computer algorithms, making keys virtually impossible to guess. It regularly refreshes these keys automatically to block long-term attacks, even as technology advances. Testing confirms the system works seamlessly with current security standards, maintaining fast performance for high-volume data transfers. The upgraded AES keeps its original security benefits while adding three key defenses: quantum-powered key creation, adjustable security settings for different threats, and safeguards against attacks that exploit device vulnerabilities. Organizations can implement this solution in stages--starting with hybrid mode for sensitive data while keeping older systems operational. This phased approach allows businesses to protect financial transactions, medical records, and communication networks today while preparing for more powerful quantum computers in the future. The design prioritizes easy adoption, requiring no costly replacements of existing hardware or software in most cases.
