The present application relates to the technical field of password security protection, and discloses a puncturable key policy attribute proxy re-encryption method based on lattice cryptography, which comprises an initialization step, an initial key generation step, an encryption step, a puncturable key update step, a decryption step, a re-encryption key generation step and a re-encryption step. The present application allows a receiver to perform a puncturing operation on a specific label locally, thereby autonomously revoking the decryption capability under the corresponding label without the intervention of a data owner or triggering global re-encryption. The receiver-driven revocation mechanism not only realizes fine-grained access control differentiated by labels, but also reduces system overhead while maintaining ciphertext reusability. The present scheme can securely support proxy re-encryption of ciphertext without exposing plaintext or master keys. Based on the security constructed on the LWE assumption, the present method supports multi-bit encryption and can provide effective security protection under quantum attack and chosen plaintext attack models.

A method performed by a machine learning system that involves obtaining a first ontology that includes one or more labels. Each label is associated with a sample that includes text. The ML system is configured to use a particular label to retrieve one or more samples associated with the particular label. The method further involves receiving an identification of a label of a first ontology associated with a first machine learning model to share with a second ontology associated with a second machine learning model and sharing the label and the information with the second ontology. The method further involves training the second machine learning model using the shared information associated with the label.

The invention relates to the technical field of password security protection, and discloses a puncturable key strategy attribute proxy re-encryption method based on a lattice password, which comprises an initialization step, an initial key generation step, an encryption step, a puncture key updating step, a decryption step, a re-encryption key generation step and a re-encryption step. According to the method, the receiver is allowed to perform puncture operation on the specific label locally, so that the decryption capability under the corresponding label is autonomously revoked, a data owner does not need to intervene or trigger global re-encryption, and the revocation mechanism driven by the receiver not only realizes fine-grained access control distinguished according to the label, but also realizes the decryption capability under the corresponding label. And system overhead is reduced while reusability of the ciphertext is maintained. According to the scheme, proxy re-encryption of the ciphertext can be safely supported on the premise that the plaintext or the master key is not exposed. Based on the security of LWE hypothesis construction, the method supports multi-bit encryption, and can provide effective security protection under a quantum attack and selection plaintext attack model.
