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 side information transmitted from distributed wireless nodes 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 hidden information can be spatially separated from that of side information. Because both the hidden and side information are necessary to obtain the secret one, the exposure region where both the hidden and side information can be demodulated without error should be narrowed. To make the exposure region narrower, this paper proposes an adaptive directivity control technique for the transmission of hidden information. Numerical results prove that the proposed technique enhances the secrecy in the secure wireless transmission scheme using distributed wireless nodes. |
