Abstract

According to an arrangement, a key management device (20) includes a generation unit (203), a packet processing unit (207), and an inter-node relay unit (209). The generation unit (203) is configured to generate a first global key based on a first random number. The packet processing unit (207) is configured to add, to a first packet including the first global key, first path information indicating a relay path for the first packet. The inter-node relay unit (209) is configured to encrypt the first packet with a local key shared with a different node and transmit the encrypted first packet to the different node.
