SECURITY ASSESSMENT METHOD AND DEVICE FOR ENCRYPTION MODEL

摘要

The present disclosure provides a security assessment scheme for an encryption model. The scheme comprises: a data demand party device sends a deployment request to a data source party device; the data source party device forwards a ciphertext model parameter and a public key in the deployment request to a security assessment party device; the security assessment party device computes a first ciphertext security assessment index by using the ciphertext model parameter and sends the first ciphertext security assessment index to the data demand party device; the data demand party device decrypts the first ciphertext security assessment index by using a private key to generate a plaintext security assessment index and forwards the plaintext security assessment index to the security assessment party device; the security assessment party device encrypts the plaintext safety assessment index by using the public key to generate a second ciphertext security assessment index, and compares the first ciphertext security assessment index with the second ciphertext security assessment index to determine consistency thereof to generate a corresponding model security assessment report; and the data source party device examines, according to the model security assessment report, whether to deploy an encrypted data model.
