COMBINATION OF AES-256 AND SHA3-512 CRYPTOGRAPHIC ALGORITHMS TO ENHANCE PDF DOCUMENT SECURITY

KOMBINASI ALGORITMA KRIPTOGRAFI AES-256 DAN SHA3-512 UNTUK MENINGKATKAN KEAMANAN DOKUMEN PDF

Abstract

Digital documents have become one of the important components in various aspects of life today, ranging from personal data storage to the exchange of sensitive business information. The threat of Interception, or attempts to unlawfully intercept information, includes situations where unauthorized parties attempt to access or retrieve data without the permission of the owner. Therefore, proper measures are required to secure digital documents from the threat of crime. One of the most effective solutions is by applying cryptography. Several previous studies have been developed by combining AES with other algorithms. One of them is by using cryptographic hash functions such as SHA-256 and SHA-512. Until now SHA is still getting more recent developments, SHA-3 being the latest version of the SHA that offers improvements in security and efficiency. This research aims to evaluate the effectiveness of combining AES-256 with SHA3-512 in protecting digital documents, especially in the context of web applications. Researchers want to provide a better security level solution by using AES-256 with SHA3-512. With this combination, documents are not only encrypted using AES-256 to protect their content, but also using SHA-3 to ensure integrity and authentication. So that this research can help provide alternatives in strengthening the security of digital documents and protecting them from various criminal threats in an increasingly complex digital environment.
