| Abstract(in English) | Recently, some papers, which apply a multi-armed bandit algorithm for channel selection in a cognitive radio system, have been reported. In those papers, channel selection based on Upper Confidence Bound (UCB) algorithm has been proposed. However, in those selection, secondary users are not allowed to transmit data over same channels at the same time. In this report, we propose secure channel selection methods based on UCB algorithm, taking the conflict between secondary users and secrecy capacity into account. Our proposed methods lead to be secure against an eavesdropper compared to conventional channel selection based on only estimated channel availability. By computer simulation, we evaluate average system secrecy capacity. As a result, we show our proposed channel selection improves average system secrecy capacity compared to conventional one. |
