  • Publication number: 20250077781
    Abstract: This application provides a classification method, device and storage medium. The classification method includes obtaining text to be processed; and processing the text to be processed based on a text classifier to obtain category information corresponding to the text, wherein the text classifier is generated based on classification guidance information and a generative pre-trained model, and the generative pre-trained model generates target classification data and its corresponding label information needed to train the text classifier based on the classification guidance information.

  • Publication number: 20250038976
    Abstract: A lattice-based proxy signature method, apparatus and device, a lattice-based proxy signature verification method, apparatus and device, and a storage medium. Polynomials are randomly selected in rings to calculate public and private keys of nodes, and the magnitudes of proxy public and private keys are the same as the magnitudes of public and private keys of an original signer. Therefore, compared with existing proxy signature schemes, the present application has smaller lengths of public and private keys and higher storage efficiency. Proxy signature information generated in the present application shows a signature of the original signer and also shows a signature of a proxy signer. Once a proxy signature is created, the proxy signature cannot be repudiated by the proxy signer, and has strong non-repudiation and strong unforgeability. The proxy signature method has the advantage of resisting quantum computer attack.

  • Publication number: 20220320649
    Abstract: An electrochemical device includes an electrode assembly, a housing, a sealing member, and a tab. The housing includes a main body portion and a sealing portion. At least a portion of the sealing member is disposed in the sealing portion, and the sealing member includes a first sealing member and a second sealing member. The tab protrudes from the sealing portion and is arranged between the first sealing member and the second sealing member. The first sealing member includes a first sealing layer and a second sealing layer disposed on the first sealing layer, and the first sealing layer is located between the tab and the second sealing layer. A melting point of the first sealing layer is lower than that of the second sealing layer, and a difference in the melting point between the first sealing layer and the second sealing layer is 35° C. to 50° C.
