Implementasi Secure Multi-Party Computation Menggunakan Metode Shamir Secret Sharing pada Pengamanan Dokumen Digital Rahasia

Willy Sudiarto Raharjo, Antonius Rachmat C., Pedro Nadirio A.

Abstract


Keamanan data merupakan aspek penting yang perlu diperhatikan dalam proses penyimpanan data. Pada beberapa situasi, terdapat data rahasia yang hanya boleh diakses apabila terdapat sejumlah pihak yang memiliki hak akses telah memberikan kontribusinya untuk mengakses data rahasia tersebut. Pada publikasi ini, kami mengimplementasikan sebuah sistem pengamanan data berbasis Multi-Party Computation dengan memanfaatkan skema Shamir Secret Sharing. Sistem yang dibangun telah mampu membagi data rahasia menjadi N potongan dan hanya setelah N potongan tersebut digabungkan kembali, data asli bisa didapatkan kembali. Kami juga mampu mengatasi sebuah persoalan integritas data yang belum dapat diatasi oleh Shamir Secret Sharing yaitu dengan memanfaatkan Hashed Key.

 

Kata Kunci: Dokumen Digital Rahasia, Keamanan Data, Skema Shamir Secret Sharing, Multi-Party Computation.
