Abstract
With the rapid development of information technology, network security problems have become increasingly prominent, and the traditional protection mechanism gradually shows its limitations in the face of distributed denial of service attacks, data tampering and identity forgery. In order to solve this challenge, this paper, based on the unique advantages of blockchain technology, puts forward an innovative network security protection mechanism, aiming to improve the security and credibility of the network system. By analyzing the decentralization of blockchain, tamper-proof and smart contracts, the research has designed and implemented a set of security fr amework suitable for multiple scenarios. Combining with cryptography algorithm and consensus mechanism, this fr amework effectively solves the problem of privacy protection and integrity verification in the process of data transmission, and enhances the traceability of the system by introducing the on-chain audit function. The experimental results show that the proposed mechanism can significantly reduce the occurrence probability of safety events and maintain high performance stability in the high concurrency environment. In addition, this paper for the first time applies the alliance chain architecture to the enterprise-level network security protection, realizes the trust and collaboration across organizations, and provides a new solution for the industry.
