【摘要】 异构开放、万物互联的未来6G网络，将面临更加严峻、复杂的安全威胁，亟需提出迭代更新的安全防护理念与安全关键技术。文章首先分析2G到5G传统移动网络协议的安全缺陷。然后，依据内生安全理念，提出6G安全域架构，对6G异构网络的安全域中协议的发展进行分析和探讨。最后，文章提出六个6G内生安全关键技术，为6G内生安全系统中协议的发展提供有力安全保障。更多还原

【Abstract】 The future 6G network is heterogeneous, open and connected to everything. It will face more severe and complex security threats. It is urgent to put forward iteratively updated security protection concepts and key security technologies. In this paper, it first analyzes the security defects of traditional mobile network protocols from 2G to 5G. After that, according to the concept of endogenous security, the 6G security domain architecture is proposed, and the development of security domain protocols in 6G heterogeneous networks is analyzed and discussed. Finally, six key technologies of 6G endogenous security are proposed, which provide strong security guarantee for the development of protocols in 6G endogenous security system.更多还原
