This paper proposes secret key transmission scheme using the products of the decomposed signals of secret signal and pseudo Gaussian signals in MIMO system. In proposed system, product signals and the reference signal of pseudo Gaussian signals are transmitted by using MIMO E-SDM and secret signal recovers from the received signal by using the products of signals and reference signals. As a result of computer simulation, we confirm the effectivity of proposed method for eavesdropper using the attack of ICA and eigenvalue decomposition.
