摘要： According to one embodiment, a node that is a root node of a network forming a directed acyclic graph topology, which is composed of plural nodes including the node serving as the root node and having a parent-child relationship among nodes of adjacent hierarchies, includes a generating unit, an encrypting unit, and a transmitting unit. The generating unit generates a group key, and a list indicating a first node to which a distribution of the group key is inhibited. The encrypting unit encrypts the group key so as to be capable of being decrypted by a first child node other than the first node out of the child nodes of the root node. The transmitting unit transmits a first message, including an encrypted group key, which is the group key that is encrypted with respect to the first child node, and the list.

摘要： A wireless mesh network includes a plurality of nodes to which a device key is assigned. The device key belongs to one of a plurality of groups. In a root node, a correspondence relationship between the nodes and the device key thereof, and a correspondence relationship between past join nodes and a device key thereof, are stored. When a new node in the wireless mesh network is detected as a past join node, the device key assigned to the past join node is assigned to the new node again. When the new node is not the past join node, a new device key is assigned to the new node. A cipher text is generated by encrypting a message using device keys assigned to the nodes and the new node. If the number of groups to which the device keys belong is fewer, a size of the cipher text is smaller.
摘要翻译：无线网状网络包括分配了设备密钥的多个节点。设备密钥属于多个组中的一个。在根节点中，存储节点与其设备密钥之间的对应关系以及过去连接节点与其设备密钥之间的对应关系。当无线网状网络中的新节点被检测为过去连接节点时，分配给过去连接节点的设备密钥再次分配给新节点。当新节点不是过去的加入节点时，新的设备密钥被分配给新的节点。通过使用分配给节点和新节点的设备密钥加密消息来生成密文。如果设备密钥所属的组数较少，则密文的大小较小。

摘要： The debugging unit writes a public key of the key issuing server and an initializing program given from outside, to the storage unit. The instruction executing unit reads and executes the initializing program stored in the storage unit. The debug disabling unit disables the debugging unit. The public-key encrypting unit encrypts the random number by the public key in the storage unit, the random number generated by the random number generating unit after the debugging unit is disabled. The transmitting unit transmits the encrypted random number to the key issuing server. The receiving unit receives an individual key encrypted by the random number from the key issuing server. The individual-key writing unit decrypts the encrypted individual key by the random number to obtain the individual key and write the individual key to the storage unit.
