 🔐 Blending Quantum & Classical Security: A Next-Gen File Encryption Scheme for the Cloud ☁️⚡

In today’s data-driven world, security and speed are no longer luxuries—they're necessities. With the rise of quantum computing 🧠💻, traditional encryption methods like RSA and ECC may soon become obsolete. So, how do we future-proof file encryption in cloud environments?

Introducing our secure and scalable file encryption scheme that combines the best of three worlds:
🔒 Post-Quantum Cryptography (PQC)
🧬 Quantum Key Distribution (QKD)
⚙️ Advanced Encryption Standard (AES)

🌐 The Problem with Current Solutions

Most existing methods only focus on secure key exchange or authentication—not full-scale file encryption for cloud storage. Our approach goes beyond that by offering a distributed encryption architecture that encrypts large files securely and efficiently.

🛠️ How It Works

🔧 We partition large files into smaller, fixed-size chunks.
🚀 These are then distributed to multiple slave nodes for parallel AES encryption.
🔐 Each node reconstructs its AES key using:

• A PQC ciphertext that holds the AES key

• A QKD-masked secret key transmitted using the BB84 protocol 🌈🔑

The master node oversees the operation:
📤 Distributes keys and subsets
📥 Collects encrypted parts
🔓 Reconstructs the full file during decryption using parallel processing

⛓️ Encryption Meets Pipeline Processing

Our pipeline overlaps:

• File I/O 🗂️

• AES encryption 🔄

• Network communication 📡

💡 Result? Less idle time and better CPU usage 🔄⚡

📊 Real-World Performance

We tested our scheme using a medical dataset 🏥📁. The results were impressive:
⚡ 2.37× faster total runtime vs. regular AES
🔒 8.11× faster encryption alone
📶 Minimal communication costs
🧠 Stable CPU usage
🧪 Quantum key management overhead? Negligible!

🚀 Why It Matters

This system brings us one step closer to a quantum-safe cloud ☁️🔐 that doesn't compromise performance. Whether you're handling sensitive health records 🩺, financial data 💸, or government files 🏛️, this hybrid encryption strategy offers scalable, future-proof protection.

🧠 TL;DR

A next-generation file encryption scheme that combines:
🔐 PQC + 🧬 QKD + ⚙️ AES
All packed into a distributed cloud architecture for high-throughput, quantum-secure encryption.
