| Popis: |
A secure OFDM transmission scheme based on two-stage chaos mapping was introduced, which were cha-oticphase rotation and sub-carrier chaos mapping. The characteristics of pseudo-random and sensitivity to initial condi-tions of chaos sequences were employed. Numerical results and analysis show that the scheme canensure secure informa-tion transmission,and improve the pseudo-randomness of transmitted signals. The eavesdropper cannot estimate the mes-sage from statistic characteristics of received signals, which guarantees the communication security. Compared with tra-ditional methods like advanced encryption standard, randomization of MIMO transmission coefficients, the scheme shows favorable computation security. |
