Abstract:

BT network has been widely used in the Internet. The nodes in BT network feature anonymity and freedom, which is more conducive to hide the identity and to create steganographic system. We used Lehmer code algorithm to construct a hidden communication system in BT network based on plugin technology. The function of this system is that a special subgroup of peers in a BT network can identify each other and communicate without suspicion among regular peers. In this process, the hidden information is transmitted and the BT network also works normally. The system makes steganographic channels secretly without exposing anyone's identity.
