In a new kind of cryptography is created: the "Golden" cryptography. It is based on the use of "Golden" matrices which are the generalization of the classical Fibonacci Q-matrix for continuous domain. In this paper, the security of "Golden" cryptography, which has been proposed recently, is tackled. Specifically, it is shown that the security of such cryptosystem is trivially compromised as it does not pass one of the basic crypt-analytic attacks: the chosen plaintext attack.
