摘　　要：The phenomenal popularity of smart mobile computing hardware is enabling pervasive edge intelligence and ushering us into a digital twin era.However,the natural barrier between edge equipment owned by different interested parties poses unique challenges for cross-domain trust management.In addition,the openness of radio access and the accessibility of edge services render edge intelligence systems vulnerable and put sensitive user data in jeopardy.This paper presents an intrusion protection mechanism for edge trust transfer to address the inter-edge trust management issue and the conundrum of detecting indistinguishable malevolent nodes launching weak attacks.First,an inter-edge reputation transfer framework is established to leverage the trust quality of different edges to retain the accumulated trust histories of users when they roam in multi-edge environments structurally.Second,a fine-grained intrusion protection system is proposed to reduce the negative impact of attacks on user interactions and improve the overall trust quality and system security of edge intelligence services.The experimental results validate the effectiveness and superior performance of the proposed intrusion protection for edge trust transfer in securing,enhancing,and consolidating edge intelligence services.
