对KLJN安全密钥交换器的瞬时攻击

Transient Attack against the KLJN Secure Key Exchanger

Shahriar Ferdous, Laszlo B. Kish

摘要:

我们证明了理想的基尔霍夫定律约翰逊噪声(KLJN)密钥交换机对瞬态攻击的安全漏洞。当Alice和Bob在每个时钟周期开始时将导线连接到他们选择的电阻器时,瞬变开始。瞬态攻击发生在很短的时间内,在从Alice和Bob的末端反射的瞬态混合在一起之前。信息泄漏是由于Eve(窃听者)监视电缆并分析这段时间内的瞬态。我们将展示这样一个瞬时攻击,然后我们介绍一个防御协议来防止攻击。计算机模拟表明,应用该防御方法后,信息泄漏变得微不足道。

英文摘要:

We demonstrate the security vulnerability of the ideal Kirchhoff-Law-Johnson-Noise (KLJN) key exchanger against transient attacks. Transients start when Alice and Bob connect the wire to their chosen resistor at the beginning of each clock cycle. A transient attack takes place during a short duration of time, before the transients reflected from the end of Alice and Bob mix together. The information leak arises from the fact that Eve (the eavesdropper) monitors the cable, and analyzes the transients during this time period. We will demonstrate such a transient attack, and, then we introduce a defense protocol to protect against the attack. Computer simulations demonstrate that after applying the defense method the information leak becomes negligible.
