Abstract
The present invention relates to a common key sharing method in an ad hoc network constituted by wireless communication terminals implemented with relay functions thereon, comprising a common key generating step in which a first wireless communication terminal responsible for relaying generates a common key, a common key distributing step in which the first wireless communication terminal responsible for relaying distributes the common key to a second wireless communication terminal within a wireless communication area, and a transferring step in which the second wireless communication terminal which received the common key holds the common key, and the second wireless communication terminal transfers the common key to a third wireless communication terminal within a wireless communication area, when the second wireless communication terminal is responsible for relaying. Accordingly, it is possible to share a common encryption key within the ad hoc network.
