Penerapan Kriptografi Keamanan Data Nilai Leger Siswa SMK Islam Kunjang Menggunakan Algoritma Asimetris RSA

Abstract

One of the most significant concerns in the field of education, and one that affects SMK Islam Kunjang, is information security. Every final exam, SMK Islam Kunjang regularly distributes file leger data—an excel file including the student scores with other schools. File-leger student grade data at SMK Islam Kunjang is susceptible to viral dissemination since people share files via email or Whatsapp. In order to prevent careless people from abusing the information in the leger file including student grades, SMK Islam Kunjang need a solution that can protect its secrecy. In this study, data on the Kunjang Islamic Vocational School students' score leger file was secured using the Rivest Shamir Adleman technique or RSA method. The most used public key encryption algorithm for protecting data is the RSA method. To generate the public and private keys, the method's performance involves selecting two random integers that will be used as keys. Critical student grade data may be encrypted and described with maximum security by utilizing the RSA asymmetric method in cryptography applications. This study demonstrates how well the RSA asymmetric approach maintains data security in the student scoreleger file at SMK Islam Kunjang.
