# Real-Time Embedded Cybersecurity and Anomalous Message Detection for In-Vehicle CAN Networks

An embedded automotive cybersecurity prototype that combines CAN traffic simulation, real-time anomaly detection, security monitoring, and ESP32-based CAN hardware design.

## 🚗 Project Overview

Modern vehicles rely heavily on Controller Area Network (CAN) communication between electronic control units (ECUs).

Because traditional CAN communication does not inherently provide strong message authentication, abnormal or unauthorized messages can become a security concern.

This project demonstrates a prototype cybersecurity system that:

- Simulates multiple vehicle ECUs

- Generates normal CAN traffic

- Generates controlled anomalous/attack traffic

- Detects suspicious CAN messages

- Performs real-time CAN traffic monitoring

- Displays security alerts through a dashboard

- Designs an ESP32 + CAN transceiver hardware interface

- Produces a PCB design and manufacturing files

**Current status:** Software prototype and PCB hardware design completed. Physical CAN hardware validation is planned as a future extension.

## 🎯 Project Objectives

1. Simulate CAN communication between multiple virtual ECUs.

2. Generate both normal and controlled anomalous CAN traffic.

3. Detect suspicious CAN messages using rule-based anomaly detection.

4. Monitor CAN traffic in real time.

5. Visualize security status through a dashboard.

6. Design an ESP32-based CAN hardware interface.

7. Verify the PCB using DRC and Gerber inspection.
