基于区块链的5G定制专网安全加强方案设计

Design of Security Enhancement Scheme for 5G Custom Private Network Based on Blockchain

摘要:

5G定制专网在工业控制、电力调度等关键领域的广泛部署，对网络安全性提出更高要求。现有集中式安全机制存在身份伪造、数据篡改与单点失效等风险，难以满足高可靠场景需求。为此，文中设计了一种融合区块链技术的5G定制专网安全增强方案，构建了多层架构并实现了分布式身份认证、数据完整性保护与日志可追溯机制。基于仿真平台的实验验证表明，该方案在保障访问可信、数据防篡改和行为审计方面表现出良好的安全性与适配性，具备实际工程推广价值。

Abstract:

The extensive deployment of 5G custom private networks in key fields such as industrial control and power dispatching has placed higher requirements on network security. The existing centralized security mechanisms suffer from risks including identity forgery, data tampering and single-point failure, which can hardly meet the demands of high-reliability scenarios. To this end, this paper designs a security enhancement scheme for 5G custom private networks integrated with blockchain technology. A multi-layer architecture is constructed to implement distributed identity authentication, data integrity protection and log traceability mechanisms. Experimental verification based on a simulation platform shows that the scheme exhibits favorable security and adaptability in ensuring trusted access, data anti-tampering and behavior auditing, and has practical value for engineering popularization.
