Drone Q-Kavach:

•The system provides a secure way to stream live video from a drone to a ground station by using advanced, future-proof encryption methods that can withstand even quantum-computer attacks.

•The drone captures video, protects each frame with strong encryption, and sends it over a single connection that can pass through multiple relay drones if needed.

•The ground station checks the identity of the drone, safely exchanges a shared secret key, and then uses that key to unlock and display the live video.

• This system offers a reliable, easy-to-deploy, and highly secure video streaming method suitable for surveillance, tactical communication, and long-range field operations.

• It prevents replay attacks by ensuring no message can be reused or faked.
• It provides future-proof encryption methods that can withstand even quantum-computer attacks.

• Authentication using Dilithium5
• Key Exchange using Kyber768
• Frame Encryption using AES-GCM

• Single Board Computers (e.g., Raspberry Pi)
