This paper proposes a novel secure wireless communication scheme using side information transmitted from nodes spatially distributed in private wireless network. In the proposed scheme, spatially distributed nodes apart from source and destination pair transmits the side information which is necessary to encrypt and decrypt the secret information. Because a detectable region of the side information can be spatially separated from that of the encrypted information by transmitting the side information from the spatially distributed node, the exposure region where the secret information is interpreted can be narrowed. Numerical results prove that the proposed scheme reduces the area of exposure region and the opportunity of eavesdropping by a malicious node.
