Secure Data Sharing in Decentralized Networks: Encryption Techniques, Access Control Mechanisms, and Data Integrity Verification

The introduction of decentralized systems in a rapidly changing technological world has introduced many issues and risks regarding privacy and secure data exchange. This paper addresses the complexities of secure data exchange within decentralized systems, focusing on encryption techniques, access control mechanisms, and data integrity verification. We begin by analyzing the impending risks and limitations within decentralized systems, including the potential for unauthorized access and data breaches from vulnerable points present in decentralized system entities. Subsequently, we analyze and explore modern methods of encryption to safeguard confidential data while also ensuring privacy. Furthermore, we examine access control strategies and integrity verification protocols, which play crucial roles in ensuring that data remains secure against unwarranted access and reliable across distributed ecosystems. Our findings emphasize the need for robust and intricate security measures adapted to the unique framework of decentralized systems. This study aims to advance the understanding of privacy and security in decentralized systems while serving as a stepping stone and valuable resource for future research.
