Cryptanalysis of Grigoriev-Shpilrain Physical Asymmetric Scheme with Capacitors

In a paper published few days ago, Grigoriev and Shpilrain propose to build a system for transmission of information without a shared secret, or essentially a sort of public key cryptosystem, based on properties of physical systems. Few days ago Grigoriev and Shpilrain have proposed to build a system for transmission of information without a shared secret, or essentially a sort of public key cryptosystem, based on properties of physical systems. In this paper, the authors show that their second scheme based on capacitors is insecure and extremely easy to break in practice.
