As a secure communication method for wireless communication systems, we propose a method utilizing the interference alignment (IA) technique. In the MIMO interference channels, only the designated pairs of two radio stations can communicate without the interference from the other communication pairs, while a third party radio station which is not included in the IA control suffers the interference. Utilizing the property, secure communication can be realized. In this paper, we propose a new method of secure communication using IA. We examine the performance of the proposed method quantitatively by computer simulations [1].
