摘要：作为万物互联时代新型的计算模型，边缘计算具有的分布式、“数据第一入口”、计算和存储资源相对有限等特性，使其除了面临信息系统普遍存在网络攻击之外，还不可避免地引入了一些新的安全威胁。为此，从4个方面对边缘计算的安全需求进行阐述，同时对其主要安全技术的设计以及实现所面临的挑战进行分析，较为全面地指出了边缘计算在身份认证、访问控制、入侵检测、隐私保护、密钥管理中存在的具体安全问题。

Abstract：As a new computing paradigm in the Internet of Everything, edge computing has the following characteristics: distributed, data first entry, relatively limited of computing and storage resources. These characteristics bring some new security threats and network attacks to the edge computing. In this paper, the security requirements of edge computing are elaborated from four aspects, and the design of its main security technology and the challenges are also analyzed. It comprehensively points out the specific security issues of edge computing in identity authentication, access control, intrusion detection, privacy protection and key management.
