This invention discloses a two-way authentication method for AB dual-lock cabinets based on SM4 and RF-ID, belonging to the field of electronic authentication technology. The invention includes: inserting an electronic key and activating the control board; the control board verifying the electronic key's identity information; collecting and encoding the mechanical key's operating status; generating a temporary session key based on the mechanical status; the control board and the electronic key performing two-way authentication; releasing the electronic lock pin upon successful authentication; recording and uploading the operation log and enabling permissions; and executing locking and alarm strategies upon authentication failure. This invention integrates the real-time operating status of the mechanical key as a dynamic seed into the SM4 session key derivation and two-way challenge-response authentication process, achieving deep real-time coupling and interlocking between electronic authentication and mechanical operation.

This invention discloses a backdoor attack method for deep neural network models, comprising: constructing and pre-training a spatial adaptive feature selection network; processing images by dividing them into blocks and inputting them into the pre-trained spatial adaptive feature selection network, and introducing a weighted ranking mechanism to generate trigger materials; constructing a feature labeling network, inputting labels into the feature labeling network to generate a label mapping map; and generating poisoned samples using the trigger materials and the label mapping map. This invention's deep neural network model backdoor attack method solves the problem of low attack success rate caused by the simple trigger structure and weak spatial adaptability in existing technologies.
