The security vulnerability of the Vadai, Mingesz, and Gingl (VMG) Kirchhoff–Law–Johnson–Noise (KLJN) key exchanger, as presented in the publication “Nature, Science Report 5 (2015) 13653”, has been exposed to transient attacks. Recently an effective defense protocol was introduced (Appl. Phys. Lett. 122 (2023) 143503) to counteract mean-square voltage-based (or mean-square current-based) transient attacks targeted at the ideal KLJN framework.

In this study, this same mitigation methodology has been employed to fortify the security of the VMG-KLJN key exchanger. It is worth noting that the protective measures need to be separately implemented for the HL and LH scenarios. This conceptual framework is corroborated through computer simulations, demonstrating that the application of this defensive technique substantially mitigates information leakage to a point of insignificance.

Vadai、Mingesz 和 Gingl (VMG) Kirchhoff–Law–Johnson–Noise (KLJN) 密钥交换器的安全漏洞，如出版物“ Nature, Science Report  5 (2015) 13653”中所述，已暴露于瞬态攻击。最近引入了一种有效的防御协议（Appl. Phys. Lett.  122 (2023) 143503）来抵消针对理想 KLJN 框架的基于均方电压（或基于均方电流）的瞬态攻击。

在本研究中，采用了相同的缓解方法来增强 VMG-KLJN 密钥交换器的安全性。值得注意的是，针对HL和LH场景需要分别实施保护措施。这一概念框架通过计算机模拟得到了证实，表明这种防御技术的应用大大减少了信息泄露的程度。
