THEORETICAL STUDY OF CRYPTOGRAPHY AS A FOUNDATION FOR DIGITAL INFORMATION SECURITY
Keywords:
Cryptography, Digital Information Security, Data Protection, CybersecurityAbstract
Cryptography plays a fundamental role in ensuring digital information security in an era characterized by rapid technological advancement and increasing cyber threats. The widespread use of digital systems for communication, data storage, and information exchange has heightened the need for reliable mechanisms to protect sensitive information from unauthorized access, manipulation, and misuse.This research adopts a qualitative descriptive methodology based on an extensive literature review of academic books, peer-reviewed journals, and authoritative publications in the fields of cryptography and information security. The analysis focuses on theoretical cryptographic constructs, including encryption algorithms, cryptographic primitives, and security models, and their relationship to fundamental information security principles such as confidentiality, integrity, authentication, and non-repudiation. The results indicate that cryptography serves as a foundational framework that enables secure digital communication, data protection, and trust establishment in digital systems. In conclusion, a strong theoretical understanding of cryptography is essential for the development and sustainability of digital information security. This study contributes to the academic discourse by emphasizing the importance of cryptographic theory as the backbone of modern digital security frameworks and as a basis for future research and innovation
