Research on Security Assurance Technology for 5G New Communication Network Architecture Based on Blockchain
With the rapid development of 5G,its openness and flexibility have brought new security challenges to communication networks.In this paper,a security scheme of 5G new communication network architecture based on blockchain is proposed,which uses the decentralized and tamper-proof characteristics of blockchain to realize distributed identity authentication,fine-grained access control based on smart contract,secure data transmission and multi-domain collaborative defense.The empirical study proves that the design scheme is superior to the traditional scheme in key indicators such as authentication success rate,authorization delay,data encryption time and network anti-attack ability,which significantly improves the overall security and credibility of the 5G network.
