边缘计算数据安全保护研究综述

Survey on Data Security Protection for Edge Computing

计算机技术的高速发展推动了外包数据服务的不断推广和应用。边缘计算作为一种新型的外包数据服务载体,被视为云计算技术的延伸。边缘计算技术已在各行各业引起了广泛关注,其应用规模也逐年扩大。但是,由于边缘计算的分布式特性,边缘实体更易受到各类安全威胁和攻击,边缘计算的数据安全保护尤为重要。首先,文章介绍了边缘计算架构并给出了常见的安全威胁模型。在此基础上,从边缘数据的安全采集、存储和共享“采、存、用”3个方面对现有边缘计算数据安全保护方法进行了分类和整理。其次,总结了现有边缘计算数据安全保护方法在上述3个方面研究上尚存的不足和挑战。最后,对边缘计算数据安全保护未来工作进行展望。

The rapid development of computer technology drives the continuous promotion and application of outsourced data services.As a new carrier of outsourcing data services,edge computing is regarded as an extension of cloud computing technology.Edge computing technology has attracted a great attention in many fields,and its ap-plication is also expanding year by year.However,due to the distribution features of edge computing,edge entities are more vulnerable to various security threats and attacks.It is particularly important for the data security protection of edge computing.Firstly,an edge computing structure is introduced,and common security threat models are given.On this basis,the existing data security protection methods of edge computing are classified from three aspects of the secure collection,secure storage and secure sharing.Secondly,the disadvantages and challenges of existing edge computing secure data protection methods are summarized in the above three aspects of research.Finally,the future work of data security protection for edge computing is prospected.
