Abstract
One method of growing vegetables is to use hydroponics by utilizing water as the medium used. In this era of rapidly developing technology, one of which is Internet of Things (IoT) is a system between computers or objects that can connect and exchange data without requiring interaction, because the data sent is public data, a security system is needed to secure the data sent. Advanced Encryption Standard (AES) 128 bits are used to secure data sent by users or data received by users, using a private key so that data security is maintained. The process of encryption and decryption was carried out through the website using an Arduino Uno microcontroller, SoC version ESP 8266. To adjust the rules for controlling plant needs such as Total Dissolve Solid (TDS), Potential Hydrogen (PH), temperature, and distance, this study uses Sensor2. Database in the research used to facilitate computerized access to assist the process of caring for IoT-based hydroponic plants. The final results have been tested in the encryption decryption process, Avalanche Effect (AE), entropy and Bit Error Ratio (BER). The AE yield 58.01% as highest score, the highest entropy was 6.3566 while all data resulted in BER = 0.
Highlights
It is easier to grow vegetables using hydroponic techniques in the era of globalization
The drawback of Internet of Things (IoT) is the use of the system
the IoT security process was carried out using cryptographic techniques
Summary
Keuntungan penggunaan IoT adalah peningkatan customer engagement, optimasi teknologi, minimalisasi pemborosan, serta enchanced data collection. Model keamanan data yang lebih mudah menggunakan IoT, dan kebutuhan dapat dilakukan menggunakan teknik penyandian data, akan keamanan sistem, maka penelitian ini penting dalam bentuk enkripsi dan dekripsi [3]. Adapun perbedaan dari penelitian yang telah dilakukan oleh [15] dengan menggunakan DES yang hanya menampilkan hasil waktu enkripsi dekripsi tanpa mengetahui ketahanan terhadap keamanan data dalam IoT. Merujuk pada [16], maka kami akan menggunakan AES dalam melakukan proses enkripsi dekripsi untuk membuktikan keamanan IoT berbasis kriptografi. Menurut [10], AES 128-bit dapat mengenkripsi file dokumen dengan sama persis pada proses enkripsi dan dekripsi yang diimplementasikan dalam teknik tunggal atau gabungan seperti steganografi [18] atau kompresi data [19]. Menggunakan substitusi addkey linier untuk akan mengalami transformasi byte, setelah itu status menghasilkan ciphertext
