Abstract

The invention discloses a deep learning model encryption and decryption method, which comprises an encryption module and a decryption module, and is characterized in that the encryption module comprises the following steps: step 1, obtaining a machine code of a to-be-deployed model device; 2, generating an ASCII (American Standard Code for Information Interchange) code value sequence table of the machine code; 3, obtaining model parameters of the pth format file, and setting the number of encryption layers and a starting encryption layer according to the maximum number of layers of the model parameters; 4, according to the ASCII code value, the value of the corresponding position of each layer of the to-be-encrypted parameters is adjusted to be a random number, the number of encryption layers and the starting encryption layer of the model parameters are set, the multiple special positions of the multi-layer parameters of the model file are adjusted in combination with the equipment machine code, and due to the fact that the number of encryption layers is set, the number of the encryption layers is increased; the starting encryption layer and the machine code are different, the adjustment parameters and positions of the model file are different, and therefore the encryption safety of the model is guaranteed, and the model deployed on a client computer is effectively prevented from being stolen at will.

Description

technical field [0001] The invention belongs to the technical field of computer engineering, and in particular relates to an encryption and decryption method of a deep learning model. Background technique [0002] Deep learning (DL, Deep Learning) is a new research direction in the field of machine learning (ML, Machine Learning), which is introduced into machine learning to make it closer to the original goal - artificial intelligence (AI, Artificial Intelligence). Deep learning is to learn the inherent laws and representation levels of sample data, and the information obtained during these learning processes is of great help to the interpretation of data such as text, images and sounds. Its ultimate goal is to enable machines to have the ability to analyze and learn like humans, and to recognize data such as words, images, and sounds. Deep learning is a complex machine learning algorithm that has achieved results in speech and image recognition far exceeding previous rela...
