During the development of 5G, much emphasis was placed on the core network and access enhancement. Slowly, the 5G fronthaul is also getting the attention it deserves to bring the entire network to the 5G world. Virtualization of network functions as well as architectural enhancement to the 5G RAN has made it necessary to re-examine the security aspect of the fronthaul. This article analyzes the security aspect of 5G fronthaul by looking at how the fronthaul evolves, from CPRI to eCPRI. With the architectural enhancement expected to support various 5G deployment models, some critically missing security enhancements in the fronthaul are also needed in the areas of security provisioning, certificate enrollment, secure environment, and synchronization plane security.

5G 前传的安全方面

5G发展过程中,重点放在核心网和接入增强上。慢慢地,5G 前传也得到了应有的关注,将整个网络带入 5G 世界。网络功能的虚拟化以及 5G RAN 的架构增强使得有必要重新审视前传的安全方面。本文通过观察前传如何从 CPRI 到 eCPRI 的演变来分析 5G 前传的安全方面。由于架构增强有望支持各种 5G 部署模型,因此在安全配置、证书注册、安全环境和同步平面安全等领域,还需要在前传中进行一些严重缺失的安全增强。
