Pengamanan Sertifikat Tanah Digital menggunakan Digital Signature SHA-512 dan RSA

Abstract

Land trading as investment is sometimes find some barriers or problems. One of the problems is illegal or misclaimed of the land certificate. Badan Pertanahan Nasional (BPN) and Pejabat Pembuat Akta Tanah (PPAT) as institutions and correlated parties in the process of land certificate making need a system to handle the problem of falsification land certificate. The purpose of this research is to make secure system of digital land certificate document with a data protection system to detect if there is a falsification activity from certain party. This research hopefully can help BPN and PPAT as authorized institution of land certificate making and to lower the number of falsification. Digital signature SHA 512 and RSA are used in this research as a solution to keep data integrity of land certificate in a digital format, in this case, in an electronic book with.pdf format. Digital signature derived from xref table in.pdf file. This program has been consulted with BPN and PPAT officer in Salatiga. The result is, this program can be used and applied for authentication process of digital land certificate and help BPN to solve the problem of high number of falsification digital land certificate.

Document Office Safety Application using Asimetric Cryptography Algorithm RSA

“…The other research is focused on Securing Digital Land Certificate by using SHA-512 and RSA Digital Signature. The result of this study indicates that the digital land certificate security system by using xref table can identify the presence or absence of significant changes in the digital certificate document file so it can be concluded that the system can verify the authenticity of the files by using SHA-512 and RSA by using the calculation process of xref table [5].…”

Penyusunan File Fingerprint untuk Berkas Jpeg/exif dengan Hash Function SHA512 dan Algoritma Boyer-Moore String Matching

“…Metadata dari berkas jpeg/exif dienkripsi sebagai acuan verifikasi keaslian berkas. Penelitian tentang keamanan informasi yang bersifat deteksi ditemui dalam penelitian oleh Refialy [3]. Penelitian ini menunjukkan hash value dari dokumen pdf dapat digunakan sebagai identitas unik untuk mendeteksi integritas data pada dokumen yang diterima.…”

Implementasi Algoritma Kriptografi Rivest Shamir Adleman (RSA) pada Tanda Tangan Digital

“…Mengamankan data sertifikat tanah digital yakni dengan menggunakan digital signature SHA-512 sebagai proses hashing bagian xreftable dari file pdf sertifikat, selanjutnya dienkripsi dengan Algoritma RSA menjadi signature kemudian disisipi ke sebuah dokumen sertifikat tanah digital. Hal ini akan mengakibatkan sistem pengamanan sertifikat tanah digital dapat mengidentifikasi ada tidaknya perubahan yang terjadi pada file dokumen sertifikat digital sehinggadapat disimpulkan bahwa sistem dapat memverifikasi keaslian dari file dengan menggunakan SHA-512 dan RSA [9].…”
