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.
