摘要
即插即用(plug-and-play)系统是一种稳定的双向系统,基于相位调制器的不完美性,可以对实际的即插即用系统进行有效的攻击,提出一种改进型的相位重映射攻击方法,从理论上推导出了相位重映射攻击所引起误码率的最小值,并考虑了通信成功率对实际攻击的影响。在这种攻击下,可获得较低的误码率和较高的通信成功率。
The plug-and-play structure is bidirectional and stable system in theory. However, the practical system can be attacked effectively due to the imperfect phase modulator. The modified phase-remapping attack is demonstrated. The minimal value of the bit error rate （BER） is derived, which is caused by the modified phase-remapping attack. The effect of the success rate of communication to the practical system is also considered. Under this attack, the BER can be kept the minimum value and a much better success rate of communication can be achieved.
