Abstract

Teknologi informasi memberikan dampak yang besar dalam aspek bisnis. Sistem informasi merupakan salah satu dampak dari kemajuan teknologi yang menjadi salah satu sarana untuk memudahkan pengelolaan informasi dan pelaporan pada sebuah perusahaan. Sistem informasi menggunakan proses autentikasi sebagai gerbang depan untuk melakukan validasi user sebelum mendapatkan layanan. Proses autentikasi memiliki kerentanan dari serangan siber, diantaranya adalah Man-in-the-middle attack. Payload autentikasi yang dikirim dan diterima pada sebuah sistem informasi perlu diamankan dengan baik. Pengiriman payload autentikasi dalam bentuk plaintext rentan akan serangan Man-in-the-middle. Teknologi Blockchain memberikan solusi keamanan berupa mekanisme blok hash untuk mengamankan data payload. Payload autentikasi sebelum dikirmkan diubah menjadi blok hash, sehingga keamanan dan kerahasiaan data payload lebih terjamin.

Abstract

Payload authentication is vulnerable to Man-in-the-middle (MITM) attack. Blockchain technology offers methods such as peer to peer, block hash, and proof-of-work to secure the payload of authentication process. The implementation uses block hash and proof-of-work methods on blockchain technology and testing is using White-box-testing and security tests distributed to system security practitioners who are competent in MITM attacks. The analyisis results before implementing Blockchain technology show that the authentication payload is still in plain text, so the data confidentiality has not minimize passive voice. After implementing Blockchain technology to the system, white-box testing using the Wireshark gives the result that the authentication payload sent has been well encrypted and safe enough. The percentage of security test results gets 95% which shows that securing the system from MITM attacks is relatively high. Although it has succeeded in securing the system from MITM attacks, it still has a vulnerability from other cyber attacks, so implementation of the Blockchain needs security improvisation.
