US 2023/0421541 A1 · INTERFACE DATA TRANSMISSION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Abstract

An interface data transmission method and apparatus, an electronic device and a storage medium are disclosed. The interface data transmission method includes: acquiring a target content stream and a content stream key corresponding to the target content stream; encrypting the target content stream according to the content stream key to obtain encrypted stream ciphertext; acquiring content control information and a shared key of a decryption terminal, and encrypting the content stream key and the content control information according to the shared key to generate a content control information list; embedding the content control information list into the encrypted stream ciphertext to generate encrypted content stream data; and sending the encrypted content stream data to the decryption terminal.

An interface data transmission method, comprising:

acquiring encrypted content stream data sent by an encryption terminal, the encrypted content stream data comprising a content control information list and encrypted stream ciphertext;
extracting content control information and a content stream key in the content control information list from the encrypted content stream data;
parsing the content control information and the content stream key by means of the shared key, and verifying integrity to obtain a first verification result;
performing verification according to the content control information to obtain a second verification result in response to the first verification result indicating that verification passes;
and
storing the content control information based on the second verification result, and decrypting the encrypted stream ciphertext according to the content control information.
