| Abstract(in English) | This paper considers secure communication of secondary user (SU) under existence of a primary user (PU) by cooperating the surrounding SUs with keeping secure communication not to leakage the information toward an eavesdropper and limiting the interference toward a primary system. We focus on the physical layer security technique, which keeps the security by using the capacity theory under PU and SU coexistence environment without giving interference toward PU. This paper proposes secondary node cooperation for improving the security. The function of each cooperative node is decided by evaluating the contribution of increasing secrecy capacity. Here, we propose two algorithms which allocate the action of SU cooperative nodes. As a result of computer simulations, we confirm that both algorithms have efficient secure performances under the limitation of transmission power of SU cooperative nodes. |
