Abstract
Di era digital modern, keamanan data menjadi prioritas utama seiring dengan meningkatnya intensitas serangan siber yang menargetkan berbagai jenis informasi, baik bersifat pribadi maupun organisasi. Penelitian ini bertujuan untuk meningkatkan keamanan data melalui pengembangan sistem enkripsi hybrid yang menggabungkan algoritma Advanced Encryption Standard (AES) 256-bit dalam mode Cipher Block Chaining (CBC) dan Elliptic Curve Cryptography (ECC). Dalam sistem ini, AES digunakan untuk mengenkripsi data utama karena kecepatan, efisiensi serta kehandalannya, sementara ECC berperan dalam mengenkripsi kunci AES sebelum didistribusikan guna memperkuat keamanan pada proses pertukaran kunci. Prototipe sistem dikembangkan pada perangkat Raspberry Pi generasi 5, yang dikenal sebagai perangkat berdaya rendah namun populer dalam pengembangan aplikasi Internet of Things (IoT). Sistem diimplementasikan dalam bentuk layanan berbasis Application Programming Interface (API) menggunakan framework Lumen dan diuji menggunakan file data berformat PDF dengan berbagai ukuran untuk mengevaluasi performa, integritas data, serta ketahanan terhadap serangan. Pengujian dilakukan termasuk simulasi serangan Man-in-the-Middle (MITM) menggunakan metode sniffing. Hasil penelitian menunjukkan bahwa Raspberry Pi 5 mampu menjalankan algoritma hybrid ini secara efisien. Proses enkripsi dan dekripsi berjalan otomatis melalui API tanpa intervensi manual, dan pertukaran kunci berhasil diamankan dari serangan MITM. Sistem juga menunjukkan performa yang stabil dan efisien untuk ukuran data hingga 160 KB, dengan waktu pemrosesan yang baik. Dengan pendekatan ini, sistem enkripsi hybrid tidak hanywa memperkuat keamanan distribusi kunci, tetapi juga dapat diimplementasikan secara praktis tanpa perlu modifikasi besar pada infrastruktur yang ada. Hal ini menjadikannya relevan untuk berbagai aplikasi berbasis IoT maupun sistem tertanam lainnya. In the modern digital era, data security has become a top priority due to the increasing frequency of cyberattacks targeting various types of information, whether personal or organisational. This study aims to enhance data security by developing a hybrid encryption system that combines the Advanced Encryption Standard (AES) 256-bit algorithm in Cipher Block Chaining (CBC) mode with Elliptic Curve Cryptography (ECC). In this system, AES is employed to encrypt the primary data due to its speed, efficiency, and reliability, while ECC is used to encrypt the AES key before distribution, thereby strengthening the security of the key exchange process. The system prototype was developed on a Raspberry Pi 5, a low-power device widely used in the development of Internet of Things (IoT) applications. The system was implemented as a service-based Application Programming Interface (API) using the Lumen framework and tested with PDF files of varying sizes to evaluate performance, data integrity, and resilience against attacks. Testing included a simulation of a Man-in-the-Middle (MITM) attack using data sniffing techniques. The results demonstrate that the Raspberry Pi 5 can efficiently execute the hybrid encryption algorithm. The encryption and decryption processes run automatically via the API without manual intervention, and the key exchange is successfully protected against MITM attacks. The system also exhibited stable and efficient performance for data sizes up to 160 KB, with processing times remaining within acceptable operational limits. This hybrid encryption approach not only strengthens key distribution security but also allows for practical implementation without major modifications to existing infrastructure, making it highly relevant for various IoT-based or embedded system applications.
