How It Works

The IoT Security System operates by securing telemetry data locally on the IndusBoard Coin before transmitting it over a Wi-Fi network. The IndusBoard Coin features built-in hardware AES support and a dedicated secure engine, allowing the microcontroller to encrypt sensitive sensor readings or system logs efficiently without heavily taxing the main processor. Using the Arduino IDE and the mbedtls library, developers can program the board to apply Advanced Encryption Standard (AES) algorithms directly to outgoing payloads. Once the data is encrypted via the hardware-backed secure engine, the microcontroller utilizes the integrated Wi-Fi capabilities to safely transmit the ciphertext across the local network to a remote server or logging station. This ensures that even if unauthorized actors intercept the wireless transmission packets in transit, the data remains unreadable without the proper cryptographic keys securely managed by the board.

Frequently Asked Questions

Why is hardware-based AES support important for this IoT project?

Built-in hardware support offloads heavy cryptographic calculations from the main processor, allowing for faster encryption and lower power consumption compared to pure software-based encryption.

What is the role of the mbedtls library in the Arduino IDE?

The mbedtls library provides the necessary cryptographic functions and protocols required to implement AES encryption cleanly within the microcontroller code.

Can this security system transmit data over standard home Wi-Fi networks?

Yes, the system encrypts the data locally first, and then uses standard Wi-Fi connectivity to transmit the secure ciphertext across your local network.
