摘要：

随着5G的到来，终端产生的数据量呈几何级数上涨，有些数据经过边缘计算后传入云计算中心，而有些数据会直接传送到云计算中心.这些数据涉及终端的各种隐私信息，例如地理位置信息，保护这些终端的隐私信息是要解决的问题.提出云边端协同隐私保护框架，主要由三个部分构成：一是安全的形式化验证，在构建云边端框架时需要考虑其安全性以及隐私保护，并进行形式化验证；二是对于攻击机理的分析，云计算中心、边缘设备以及终端设备所面临的攻击有所不同，而自身具备的能力也不同，从数据层面、模型层面以及系统层面进行安全及隐私分析；三是防御策略构建，主要是模型安全及隐私诊断、攻击行为诊断以及策略协同防御.通过隐私保护框架的构建，对云边端系统进行隐私保护.

关键词: 云边端协同, 边缘计算, 隐私保护, 隐私保护框架, 边缘隐私保护

Abstract:

With the arrival of 5G，the amount of data generated by terminal increases geometrically. Some data are transmitted to the cloud computing center after edge computing，while some are directly transmitted to the cloud computing center. These data involve all kinds of privacy information of terminals，such as geographic location information. To protect the privacy information of these terminals，this paper proposes a cloud edge collaborative privacy protection framework，which is mainly composed of three aspects. The first is the formal verification of security，that is，we need to consider its security and privacy protection，and carry out formal verification when building the cloud edge framework. The second is the analysis of attack mechanism. Attacks faced by cloud computing center，edge devices and terminal devices are different，as well as their own capabilities. The security and privacy analysis is carried out from the data level，model level and system level. The third is the construction of defense strategy，mainly including model security and privacy diagnosis，attack behavior diagnosis and policy collaborative defense. Through the construction of privacy protection framework，the cloud edge system is privacy protected.

Key words: cloud edge collaboration, edge computing, privacy protection, privacy protection framework, edge privacy protection
