摘要
边缘计算将传统的云服务扩展到网络边缘,更贴近用户,适用于具有低时延需求的网络服务。随着边缘计算范式的兴起,其安全问题也得到越来越多的关注。首先介绍了边缘计算范式的基本概念、系统架构以及与其他计算范式的关系。然后分析了当前边缘计算中存在的安全威胁,并针对各种安全威胁探讨了相应的安全技术问题。最后对边缘计算安全技术中关键的入侵检测、访问控制、防御策略、密钥管理技术进行了分析,并提出了进一步研究方向。
With the rise of edge computing, more and more attentions have been paid to security issues of edge computing. The basic concepts, system architecture and the relationship between edge computing and other computing paradigms were introduced. Then the security threats to edge computing were analyzed, and the security technology of edge computing was discussed for these security threats. Finally, the technologies of intrusion detection, access control, defense strategy and key management in edge computing were summarized and the further research directions were pointed out.
