对KLJN安全密钥交换系统的静态环流攻击

A Static-Loop-Current Attack against the KLJN Secure Key Exchange System

Mutaz Y. Melhem, Laszlo B. Kish

摘要:

提出了一种针对Kirchhoff定律-Johnson-Noise(KLJN)密钥分发系统的新的攻击方法。该攻击是基于利用寄生直流电压源的环路。在实际系统中,由于接地回路和/或电磁干扰(EMI),在低频限制下经常存在相关情况,特别是当通信距离较远时。令人惊讶的是,通常的基于电流/电压比较的防御方法暴露了主动攻击或寄生特征(例如允许信息泄漏的导线电阻),但在这里不起作用。攻击被成功证明。提出了针对它的防御方法。

英文摘要:

A new attack against the Kirchhoff-Law-Johnson-Noise (KLJN) key distribution system is explored. The attack is based on utilizing a parasitic dc-voltage-source in the loop. Relevant situations often exist in the low-frequency limit in practical systems, especially when the communication is over a distance, due to a ground loop and/or electromagnetic interference (EMI). Surprisingly, the usual current/voltage comparison based defense method that exposes active attacks or parasitic features (such as wire resistance allowing information leak) does not function here. The attack is successfully demonstrated. Proposed defense methods against it are shown.
