Method and apparatus for neural network model encryption and decryption

A method for neural network model decryption applied in a second apparatus, wherein the neural network model is stored in a first apparatus, an encryption key is obtained based on a hardware configuration information of the first apparatus applying the neural network model, the method comprises:

• the second apparatus obtaining an encrypted neural network model encrypted by the first apparatus from the first apparatus;
• if the encrypted neural network model is invoked, the second apparatus transmits a decryption request to the first apparatus, if the second apparatus is determined to be an authorized apparatus by the first apparatus, obtaining the hardware configuration information from the first apparatus;
• in response to the hardware configuration information, the second apparatus obtains a decryption key based on the hardware configuration information;
• and
• if the decryption key matches the encryption key, decrypting the encrypted neural network model by a predetermined decryption algorithm.
