Current injection and voltage insertion attacks against the VMG-KLJN secure key exchanger. (arXiv:2210.05121v2 [cs.CR] UPDATED)

In this paper, the vulnerability of the Vadai, Mingesz and Gingl (VMG)-
Kirchhoff-Law-Johnson-Noise (KLJN) Key Exchanger (Nature, Science Report 5
(2015) 13653) against two active attacks is demonstrated. The security
vulnerability arises from the fact that the effective driving impedances are
different between the HL and LH cases for the VMG-KLJN scheme; whereas for the
ideal KLJN scheme they are same. Two defense schemes are shown against these
attacks but each of them can protect against only one of the …
