Research on Security Mechanisms of Distributed Information Systems Based on Blockchain Technology

Abstract

This study deeply analyzes the security mechanism of distributed information system based on blockchain, and describes the advantages and disadvantages of blockchain technology and distributed information system respectively. By strengthening node management, establishing a distributed ledger, reaching a consensus mechanism, adding encryption algorithms, and other dimensions on the innovative path, to build a secure distributed information system, enhance the system's data security, network trustworthiness, and privacy protection capabilities, and further enhance the system's ability to withstand attacks. At the same time, the practical cases of this system in the supply chain field also fully verify its feasibility and application value. Although there are certain performance bottlenecks, with the iterative evolution of blockchain technology and its in-depth integration with emerging technologies, the security of distributed information systems is expected to move to new heights, providing solid support for the booming digital economy and the digital transformation of various industries.
