Perlindungan Data Sensor Menggunakan Three-Pass Protocol dengan ESP 32

Abstract

In the current digital era, data security has become a very important aspect, especially in the context of the Internet of Things (IoT) where sensor devices are often used to collect and transmit data. This research aims to develop a method for protecting sensor data using the Three Pass Protocol with the ESP32 device as the main platform. Three Pass Protocol was chosen because of its ability to secure data without requiring the exchange of secret keys that are vulnerable to interception. This research involves implementing the Three Pass Protocol using the XOR (Exclusive OR) encryption algorithm on ESP32. In this scenario, the ESP32 acts as a sender (Alice) and receiver (Bob) who exchange encrypted data. Implementation is carried out using the Arduino IDE to program the ESP32. The research results show that the use of the Three Pass Protocol on the ESP32 can significantly increase sensor data security. Data sent and received via this protocol is proven safe from third party eavesdropping. In addition, the ESP32's performance in running this protocol is quite efficient, making it a feasible solution to be implemented in systems that require a high level of security. Thus, this research makes an important contribution in the field of sensor data security, especially in terms of protecting DHT11 sensor data using the Three Pass Protocol. It is hoped that this implementation can become a reference and benchmark for the development of sensor data security systems in the future.
