Abstract (in Japanese) (See Japanese page) 
(in English) Because of the vulnerable and unpredictable propagation of wireless signal, secure communications against eavesdropper is one of the important requirements in wireless networks. For satisfying this requirement, a secure wireless transmission scheme using wireless nodes in a distributed wireless networks has been proposed. In the scheme, a distributed wireless node existing apart from source and destination nodes transmits side information required to make hidden information and extract original secret information, and the propagation area of secret information transmitted from source node can be spatially separated from that of side information. Because both the hidden and side information are necessary to obtain the secret one, in order to enhance the secrecy of secret information, the exposure region where both the hidden and side information can be received without error should be narrowed. To make the exposure region narrower, this paper proposes a dynamic side information node selection technique. In the proposed technique, the side information node is dynamically selected among distributed wireless nodes according to the channel condition. Numerical results prove that the proposed dynamic node selection technique enhances the secrecy in the secure wireless transmission scheme using distributed wireless nodes.
