Abstract
An encryption and signature device for AI model protection is provided. The encryption and signature device for AI model protection includes a key derivation unit, a model encryption unit, a model password encryption unit, an image generation unit and a signature unit. The key derivation unit is configured to derive a model key according to a model password and a derivation function. The model encryption unit is configured to encrypt an AI model according to the model key to generate an encrypted AI model. The model password encryption unit is configured to encrypt the model password to generate an encrypted model password. The image generation unit is configured to generate an image file according to the encrypted model password and the encrypted AI model. The signature unit is configured to sign the image file according to a private key to obtain a signed image file.
