Patent Searching and Data


Title:
DATA TRANSMISSION MANAGEMENT METHOD, AND DATA PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/060630
Kind Code:
A1
Abstract:
The present application discloses a data transmission management method, and a data processing method and apparatus, and relates to the technical field of computers. A specific embodiment of the method comprises: in response to a received key acquisition request sent by a client, obtaining a first key from a key pool; asymmetrically encrypting the first key using a public key of the client, and generating a ciphertext corresponding to the first key; sending the ciphertext to the client, allowing the client to use the key corresponding to the public key to decrypt the ciphertext so as to obtain the first key, the first key being used by the client to symmetrically encrypt source data to be transmitted. The embodiment uses an asymmetric encryption algorithm to encrypt a key, thereby ensuring secure transmission of the key, and uses the key based on a symmetric encryption algorithm to encrypt transmitted data, thereby improving data encryption and decryption efficiency, and satisfying the high-security and high-efficiency requirements of a client and serving end for the frequent exchange of sensitive data.
