Abstract
With the rapid development of information technology, cybersecurity issues have become increasingly prominent, posing numerous challenges to traditional security protection mechanisms. Blockchain technology, characterized by its decentralization, immutability, and cryptographic algorithms, demonstrates significant potential in the field of cybersecurity. This study aims to explore the construction of a novel cybersecurity protection mechanism based on blockchain technology to address existing security threats in the current network environment. By analyzing the vulnerabilities and inadequacies of the current cybersecurity protection systems and integrating the core principles of blockchain technology, we propose a comprehensive protection fr amework that incorporates identity authentication, encrypted data transmission, and access control. This fr amework utilizes smart contracts for automated policy management, employs a distributed ledger to ensure data integrity, and introduces zero-knowledge proofs to optimize privacy protection. Experimental results indicate that the proposed protection mechanism can effectively resist various types of network attacks and significantly enhance system security and stability. Notably, it performs exceptionally well in defending against DDoS attacks, preventing data breaches, and safeguarding user privacy. Innovatively applying blockchain technology to cybersecurity protection, this research not only compensates for the deficiencies of traditional protective measures but also provides new ideas and technical support for building a more reliable and efficient cyberspace in the future, which is of great significance to the advancement of cybersecurity technology.
