携带诱骗信息的多层网络隐写方法

为了提升网络隐写方法中秘密信息隐蔽传输的安全性，研究了携带诱骗信息的多层网络隐写方法。方法分为两层，高层方法用于携带诱骗信息欺骗检测者，低层方法利用网络协议栈纵向多协议之间的关系编码秘密信息，实现隐蔽通信。实验结果表明，该方法能够在保证隐写带宽的同时，确保了秘密信息传输的安全性。
In order to improve the security of covert information transmission in network steganography, a decoy method of multi-level steganography based on vertical multi protocol collaboration was proposed. The proposed method consisted of 2 levels. The upper level was used to carry the decoy message to deceive the detector. The lower level used the vertical relationship of multi protocol to encode steganogram. Experimental results show that the proposed method is more undetectable than others due to the usage of decoy message and multi level steganography.
