### Cryptanalysis of Grigoriev-Shpilrain Physical Asymmetric Scheme With Capacitors

Nicolas T. Courtois

##### Abstract

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 we show that their second scheme based on capacitors is insecure and extremely easy to break in practice.
