Cryptanalysis of Grigoriev-Shpilrain Physical Asymmetric Scheme With Capacitors
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 [2]. In this paper we show that their second scheme based on capacitors is insecure and extremely easy to break in practice.
