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.

Abstract: A data transmission method, an electronic device and a computer-readable storage medium are disclosed. The method is applied to a topological connection, the topological connection including a source node and first-level sub-nodes. The method includes: selecting, according to the source node, a first-level sub-node to which digital content is issued by the source node; establishing an authentication channel between the first-level sub-node and the source node; adjusting a counting parameter of the source node according to the authentication channel, and acquiring an authentication identifier of the first-level sub-node; and issuing the digital content to the first-level sub-node according to the authentication identifier if the adjusted counting parameter is smaller than a preset threshold.
