Perbandingan Performance Kriptografi RSA, RSA-CRT, Rabin dalam Proses Pengamanan Pesan Berbasis Teks

Deby Cynthia Rohara Manalu — 2024-12-28

Data security is a critical aspect in the digital era, especially in securing text-based messages. This research compares the performance of three asymmetric cryptography algorithms-RSA, RSA-CRT, and Rabin-in terms of the speed and efficiency of the encryption and decryption process. The RSA (Rivest-Shamir Adleman) algorithm, one of the most popular cryptographic methods, uses two different keys (public and private) to encrypt and decrypt data, but has a weakness in decryption time efficiency on large data. RSA-CRT, as a modification of RSA with the Chinese Remainder Theorem approach, speeds up the decryption process by dividing large operations into smaller ones. Rabin's algorithm, which is based on prime factorization, shows high time efficiency for both encryption and decryption processes, although it produces four possible plaintexts that require additional selection. All three algorithms were tested using text data with varying character sizes, ranging from 100 to 10,000 characters. The test results show that RSA has the fastest encryption time, RSA-CRT excels in decryption, and Rabin offers the best overall efficiency for securing text-based data. This research provides algorithm recommendations according to system needs, taking into account the balance between efficiency and security.

Cigarette smoke is one type of air pollutant that can cause various health problems, such as coughing, cancer and other health problems, especially when accumulated in the house, especially in the living room which is often used for gathering. This research aims to design and build an Internet of Things (IoT)-based cigarette smoke neutralization device that utilizes MQ-2 and MQ-135 sensors to detect the presence of smoke and harmful substances. The method used in this research is the waterfall method, which includes requirements analysis, design, implementation, testing, and maintenance. The development process of this tool is carried out systematically. This tool is equipped with a bot telegram notification system that provides real-time information to users regarding the air quality in the living room. When the sensor detects pollution levels exceeding the threshold, the device will activate the fan to increase air circulation and utilize the exhaust fan to neutralize smoke. In addition, the sound output from the speaker provides information about the air quality and notifies that the room has been successfully neutralized. Based on the test results, this prototype tool is able to detect air quality and takes ±1 minute to neutralize a room contaminated with smoke > 10 ppm while for smoke levels > 50 ppm, it takes ±2 minutes to create a healthy environment for the occupants. This research is expected to provide an innovative solution to the problem of smoke pollution and the implementation of indoor smoking bans.
