Abstract:

With the development of the mobile internet and IoT (internet of things),mass data are stored in the cyberspace.The network security and privacy are of great significance.The blockchain-based network security mechanism has the properties of decentralization,tamper-resistance,traceability,high availability and credibility,and can be applied to improve network security.The application of blockchain in the network security was explored.The main technologies and the future research direction of the blockchain-based network security mechanism were analyzed.Firstly,the blockchain-based data protection scheme was analyzed,which applied the tamper-resistance of the blockchain to improve the authenticity and reliability of data.Secondly,the blockchain-based IoT device management scheme was analyzed,which applied the blockchain to record and execute the device control instruction and improve the authority and communication of the IoT devices.Lastly,the blockchain-based domain name system was analyzed,which applied the decentralization of the blockchain to resist distributed denial of service effectively.

Key words: network security, privacy, blockchain
