摘要:

提出了一种新的对Kirchhoff-Law-Johnson-Noise(KLJN)安全密钥交换方案的攻击。该攻击利用Alice或Bob端的寄生(周期性)AC电压源。由于交流接地回路和电磁干扰(EMI),存在这种情况。在低频情况下,该过程是以前基于DC接地回路的攻击的一般形式。在高频情况下,利用线电压的功率谱。在低频率和高频率情况下都证明了攻击。针对攻击的防御协议也进行了讨论。

英文摘要:

A new attack against the Kirchhoff-Law-Johnson-Noise(KLJN) secure key exchange scheme is introduced. The attack exploits a parasitic (periodic) AC voltage-source at either Alice or Bob ends. Such situations exist due to AC ground loops and electromagnetic interference (EMI). In the low-frequency case, the procedure is the generalized form of the former DC ground loop based attack. In the high-frequency case, the power spectrum of the wire voltage is utilized. The attack is demonstrated in both the low and the high-frequency situations. Defense protocols against the attack are also discussed.
