Research progress of edge computing security and privacy-preserving

Abstract： The rapid development of information technologies such as the Internet of Things and 5G accelerates the arrival of the era of the Internet of Everything,the explosive growth of network edge devices has produced massive edge data,the centralized big data processing of the traditional cloud computing model has been unable to meet the efficient processing of massive data of edge devices,therefore, edge computing comes into being at the right time.As a new computing model, edge computing provides services closer to the user′s network edge side,which reduces the network load and enhances the response ability. However, due to the openness and multi-source heterogeneity of the edge environment, the resources of edge nodes restriction and other characteristics make the security and privacy-preserving of edge computing faces many challenges.Firstly, the basic concept of edge computing is introduced,and then from the perspective of security requirements,focusing on the key technologies such as identity authentication, communication security protocol, intrusion detection and privacy-preserving,the research achievements in the field of edge computing security and privacy-preserving at home and abroad are systematically described and analyzed.Finally, the possible research directions in the future are proposed.
