Abstract
A communication device includes a processor. The processor monitors a first message that is periodically transmitted from a representative device in a first network. The processor transmits a second message to the communication devices in the first network when the first message is not detected. When plural data components obtained by dividing authentication information have been distributed from the representative device plural communication devices in the first network, the processor receives data components transmitted from the communication devices in the first network in response to the second message. When a specified number of data components are received, the processor regenerates the authentication information from the specified number of data components. The processor generates new authentication information by rewriting at least a portion of the regenerated authentication information. The processor connects to a second network based on the new authentication information.
