基于随机数发生器的Kirchhoff-Law-Johnson-Noise安全密钥交换协议攻击

Random Number Generator Attack against the Kirchhoff-Law-Johnson-Noise Secure Key Exchange Protocol

Christiana Chamon, Shahriar Ferdous, Laszlo B. Kish

摘要:

本文介绍并证明了两种针对Kirchhoff定律-Johnson-Noise(KLJN)安全密钥交换方案的新攻击。这些攻击基于安全性受损的随机数生成器。首先,我们探讨的情况下,夏娃都知道爱丽丝和鲍勃的随机数发生器的种子。我们表明,在这种情况下,夏娃可以破解的安全密钥位内的一小部分的位交换周期,即使她的电流和电压测量只有一个单一的位的分辨率。在第二次攻击中,我们探讨了夏娃只知道爱丽丝的随机数生成器的种子的情况。我们表明,在这种情况下,夏娃仍然可以破解的安全密钥位,但她需要使用整个位交换期间的攻击。KLJN密钥交换方案的安全性与其他协议类似,需要随机数生成器输出对于Eve是真正随机的。

英文摘要:

This paper introduces and demonstrates two new attacks against the Kirchhoff-Law-Johnson-Noise (KLJN) secure key exchange scheme. The attacks are based on random number generators with compromised security. First we explore the situation in which Eve knows the seed of both Alice's and Bob's random number generators. We show that in this situation Eve can crack the secure key bit within a fraction of the bit exchange period even if her current and voltage measurements have only a single bit of resolution. In the second attack, we explore the situation in which Eve knows the seed of only Alice's random number generator. We show that in this situation Eve can still crack the secure key bit but she needs to use the whole bit exchange period for the attack. The security of the KLJN key exchange scheme, similarly to other protocols, necessitates that the random number generator outputs are truly random for Eve.
