Securing Data Files Using RSA-ElGamal and Diffie-Hellman Algorithms

Abstract

Data security involves efforts to protect and ensure three key aspects in the cyber realm: the confidentiality, integrity, and availability of data. It assures cyber users that their privacy is safeguarded, whether on personal computers, mobile devices, or during internet browsing activities. The objective of this study is to authenticate data while applying the SHA-256 function in cryptographic algorithms. Utilizing a combination of the Diffie-Hellman, RSA, and ElGamal algorithms can offer a strong solution to enhance the security of PDF files against various security threats
