Model generation method and device and electronic equipment

The invention discloses a model generation method and device and electronic equipment. The method comprises the following steps: acquiring encrypted training data; decrypting the encrypted training data by using a predetermined key to obtain original training data; performing predetermined vectorization processing on the original training data to obtain target vector data; a node sequence for processing the target vector data is determined, the node sequence comprises a plurality of nodes, the plurality of nodes form an initial model, the nodes comprise at least one function layer of the initial model, and the node type corresponding to the nodes is any one of the following types: a first node type based on a trusted platform module chip, a second node type based on the trusted execution environment; and inputting the target vector data into the node sequence to train the initial model to obtain a target model. According to the method and the device, the technical problem that the privacy exposure phenomenon
