The invention discloses a covert communication method based on a webpage link request. The method comprises a first step of arrangement of configuration items on a sending terminal and a receiving terminal; a second step of sending method of the covert communication of the sending terminal; a third step of information receiving method of the receiving terminal; and a fourth step of recovery of an original ciphertext by the receiving terminal. Through adoption of the covert communication method based on the webpage link request, the transmission reliability of the covert information is effectively improved, the anti-detection performance of a covert channel is improved greatly, and the covert communication method based on the webpage link request has a broad market prospect in popularization
