Abstract

This research aims to develop a text file security system using the NTRU cryptographic algorithm. This process begins with understanding the basic principles of NTRU, which uses a polynomial-based mathematical structure to generate key pairs. The public key is used to encrypt text files, while the private key is used to decrypt them. The research stages include generating public-private keys, followed by the process of encrypting text files into ciphertext and decrypting to restore the files to their original form. The result of this research is a system capable of effectively securing text files using NTRU encryption. This system is expected to contribute to improving digital information security, especially in protecting the confidentiality of text files. This research report will provide insights and detailed steps regarding the implementation of NTRU. This research is expected to be a guide for developers and researchers in implementing NTRU to strengthen broader data security.
