Abstract

This invention discloses a quantum audio steganography-based secure information transmission method in the field of communication security technology, applied to a transmitting and receiving end in mutual communication. The method includes: acquiring audio data; processing the audio data using a QRDA model to obtain quantum audio data; after receiving secret information at the transmitting end, encrypting the secret information with a key and embedding it steganographically into the quantum audio data to generate transmission data and sending it to the receiving end; after receiving the transmission data at the receiving end, extracting and decrypting the steganography from the transmission data to obtain the secret information. This invention uses a QRDA model to convert secret information into a quantum state suitable for steganography. It embeds traffic information into the quantum audio using the EMD algorithm, and then uses a randomly generated key for encryption and decryption. While ensuring stable transmission of traffic information, it leverages quantum advantages to improve the security and efficiency of transmission.
