SECURELYNK

 SecureLynk – Secure IoT Data Transmission Using Docker & Cloud Introduction The Internet of Things (IoT) is transforming how devices connect and exchange information. But as the volume of IoT data grows, so do the risks — unauthorized access, data tampering, and insecure communication channels. SecureLynk is a hands-on project designed to demonstrate secure IoT data transmission using a three-tier Dockerized architecture . The system integrates three main components: IoT Simulator – generates and sends random IoT messages. Cloud Application – encrypts and stores messages securely. Receiver Dashboard – decrypts and displays messages for authorized users. Each component runs in its own Docker container, communicating over a virtual network and sharing a common SQLite database. Lightweight encryption is achieved through a combination of XOR Cipher and Base64 Encoding , ensuring data confidentiality throughout the transmission process. This tutorial walks you throu...
