Abstract
Disclosed is an area restricted network management method including a step of detecting, in a first area restricted network, one or more second area keys sent from one or more second area restricted networks; a step of generating a first hierarchical area key which is related to a first area key generated by the first area restricted network as well as at least one of the detected one or more second area keys; and a step of transmitting the first hierarchical area key to inside of the first area restricted network.
Claims10
An area restricted network management method comprising:
- detecting, in a first area restricted network, one or more second area keys sent from one or more second area restricted networks;
- generating a first hierarchical area key which is related to a first area key generated by the first area restricted network as well as at least one of the detected one or more second area keys;
- and
- transmitting the first hierarchical area key to inside of the first area restricted network.
An area restricted network management device comprising:
- a detection part configured to detect, in a first area restricted network, one or more second area keys sent from one or more second area restricted networks;
- a generation part configured to generate a first hierarchical area key which is related to a first area key generated by the first area restricted network as well as at least one of the detected one or more second area keys;
- and
- a transmission part configured to transmit the first hierarchical area key to the inside of the first area restricted network.
