Abstract
A communication system, including: a NW management device which (i) forms a network together with an authenticated target device, and (ii) manages the network by delivering a session key for use in communication in the network to the authenticated target device; and a device authenticated by the NW management device, wherein the NW management device: determines whether or not to permit the device to be an alternative management device which manages the network in replace of the NW management device when communication is impossible in the network; shares, with the device, authentication information about the authenticated target device, when permitting the device to be the alternative management device; and the device shares the authentication information with the NW management device, and starts managing the network using the authentication information as the alternative management device when determining that the NW management device cannot communicate in the network.
