Data Security in Intelligent System for Road Maintenance Using Encryption and HTTPS

A highly maintained toll road decreases accident risk, improves traffic efficiency, and enhances infrastructure feasibility, resulting in reduced maintenance costs. This study presents the implementation of data security in an intelligent toll road maintenance system using AES encryption and HTTPS protocols. The proposed system consists of NodeMCU ESP-12 as the microcontroller, MPU6050 accelerometer for measuring vehicle vibrations, Neo-6M GPS module for location tracking, and an SD card module for data storage. The collected data is encrypted using AES before being transmitted securely over HTTPS. Experimental results show that the system enhances data security with an encryption time of 1884 ms using AES+HTTP and 5721 ms using AES+HTTPS, demonstrating the feasibility of this approach despite the increased processing time.
