Abstract: The Advanced Measurement System (AMI) is the basis for smart grid systems to measure,collect,store,analyze and manipulate user-consumed data.The communication and data transfer requirements between consumers (smart meters) and utilities significantly reduce the security of AMI.The electricity information collection system uses a variety of communication methods,communication protocols and new intelligent collection terminals.Therefore,the network attacks faced by the electricity information collection system are extremely frequent.Since the system currently focuses on the uplink rate of the acquisition terminal and the connectivity of the communication channel,there is a lack of corresponding security protection measures.Aiming at the above problems,the deployment scheme of the virtual honeynet on the power information collection system was designed and implemented,which solves the problem of waste of traditional honeynet hardware resources.At the same time,the data control algorithm is designed to detect the data packet,which effectively solves the control problem of attack traffic.Finally,the penetration attack test was carried out,and the experimental results are analyzed by combining the three core functions of the honeynet,which show that the scheme can effectively detect the attack.
