Abstract: With the development of information,communication and Internet of Things technologies,the number of devices connected to the Internet and the amount of data generated have increased exponentially,resulting in a number of new application scenarios.The traditional cloud-based centralized big data processing mode cannot fully meet the needs of the new application scenarios.Edge computing is a new computing model that migrates some or all of the computing tasks of the original cloud computing center to the vicinity of the data source.It has gradually attracted widespread attention from various industries.Relevant enterprises,industrial organizations and open source platforms have published a series of reference architectures for edge computing,which these documents are highly security focused.In this paper,the existing reference architectures for edge computing are collated and analyzed,and it is found that defense-in-depth and overall security operation are the effective ways to solve the security problem of edge computing.However,there is no independent security reference architecture to systematically describe the security of edge computing,and this is not conducive to the promotion and application of edge computing.This paper gives some preliminary suggestions from the aspects of security objectives,security management,security technology and application fields.
