A Data Validation Method Based on IP Covert Channel Packet Ordering

Information hiding technology based on IP covert channel is a research hotspot. Although the existing packet ordering IP covert channel can realize data transmission, it is unable to judge the correctness of data transmission due to the lack of data verification. In this paper, a data verification method based on packet ordering IP covert channel is proposed. Two different covert data transmission methods are used for data transmission, and data verification is carried out after the transmission of data is completed. Experiments show that the method proposed in this paper can realize data verification and can use retransmission mechanism to retransmit data after data is different.
