Quantum-Resistant Key Exchange Demo Kit with Raspberry Pi 4 + DHT22
Quantum-Resistant Key Exchange Demo Kit with Raspberry Pi 4 — Secure IoT Communication Against Future Attacks
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Quantum computers threaten current public-key encryption. This kit lets you build a hardware demo that replaces vulnerable key exchange with CRYSTALS-Kyber—a NIST-standardised post-quantum algorithm. A Raspberry Pi 4 performs the Kyber handshake, shares a symmetric key with an ESP32, and the ESP32 encrypts real-time DHT22 temperature/humidity data using AES-256. The 0.96-inch OLED displays the ciphertext and plaintext side-by-side, proving the system’s resistance to quantum decryption.
What You'll Build
A fully functional IoT sensor node that establishes a quantum-resistant shared secret. The Raspberry Pi acts as the key encapsulation server, while the ESP32 wirelessly receives the key over serial, then loops through DHT22 readings, encryption, and display updates. You’ll see the entire chain—from mathematical key derivation to ciphertext verification—on your desk, ready for demonstration or further research.
What You'll Learn
- Implement CRYSTALS-Kyber-768 key encapsulation on Raspberry Pi 4 using Python libraries
- Establish a serial key transfer protocol between Pi and ESP32 with error detection
- Perform AES-256 encryption/decryption of DHT22 sensor data in real-time on the ESP32
- Integrate a 0.96-inch OLED to display encrypted and decrypted sensor values alternately, confirming cryptographic correctness

Who This Kit Is For
Final-year B.Tech ECE/EEE students, cybersecurity enthusiasts, and researchers exploring post-quantum IoT security. If you're building a Smart India Hackathon prototype, a master’s thesis, or an IIT/NIT/VIT/BITS capstone project, this kit gives you a tangible, hardware-driven demonstration of NIST’s selected algorithms. You’ll need basic familiarity with Python, Arduino IDE, and cryptographic concepts—this is not a beginner’s kit.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with the AI companion trained on the exact Kyber-to-ESP32 handshake steps. If you need human help, WhatsApp support is included.
Do I need prior knowledge of post-quantum cryptography?
The kit assumes you understand basic symmetric/asymmetric encryption. The AI companion walks you through Kyber’s key encapsulation step-by-step, but complete beginners to cryptography may struggle.
Can I use this for a Smart India Hackathon project?
Yes. The demo shows quantum-resistant sensor security—a strong foundation for healthcare, defence, or smart city themes. Hardware is ready; you can focus on software customisation.
Does the MicroSD card come preloaded with required libraries?
Yes, the card contains a base Raspberry Pi OS image with liboqs and Kyber libraries installed. You may need to update packages via apt, but the critical dependencies are already there.
Raspberry Pi runs Kyber post-quantum key exchange. ESP32 uses derived key for AES sensor data encryption.
