Abstract

The main subject of this work is to propose and analyze steganographic systems using WiMAX (802.16-2004) networks physical layer (PHY). According to this, two new systems were described. These proposals allow to create additional, hidden for unauthorized users channels used to transmission of secret messages. First one - System I uses frames padding and second one - System II is based on properties of RS error correction code that is used in WiMAX. Effectiveness of proposed systems was assessed on the base of simulations. For that purpose SIMULINK, which is the part of MATLAB, proved to be the best solution. Built models, which imitate network´s physical layer, allow to evaluate systems in terms of effectiveness, security and costs of using.
