20130336484 | TRANSMITTING DEVICE, RECEIVING DEVICE, WIRELESS COMMUNICATION SYSTEM AND METHOD FOR CONTROLLING WIRELESS COMMUNICATION SYSTEM - A transmitting device, a receiving device, a wireless communication system and a method for controlling the wireless communication system are used for creating a secure wireless communication network of a limited area. The transmitting device comprises: one or more transmitters configured to transmit wireless signals, and create the limited area by a coverage scope of the wireless signals; a cryptography key generating unit configured to generate a cryptography key for the wireless signals; a cryptography key encoding unit configured to encode the cryptography key to a cryptography key frame; and a cryptography key scheduling unit configured to schedule the cryptography key frame so as to control the transmitter to transmit the wireless signals including the cryptography key frame. | 12-19-2013 |
20130336485 | METHOD OF CONTROLLING STATES OF MOBILE NODE AND VERIFIER THEREIN FOR RECEIVING SECRET KEY - Disclosed are a verifier used in a mobile node and a method of controlling plural states of the mobile node. The verifier comprises a secret key receiving part configured to listen and receive at least one secret key from at least one secret key transmitter in an area limited Ad-hoc network; a secret key stamp generating part configured to perform calculation on the at least one secret key according to a predetermined verification rule so as to generate a secret key stamp; and a secret key stamp verifying part configured to compare the secret key stamp and a predetermined standard value, wherein, if the secret key stamp is equal to the predetermined standard value, then the secret key is determined as valid, otherwise, the secret key is determined as invalid. | 12-19-2013 |
20140126416 | AREA-LIMITED SELF-ORGANIZED NETWORK MANAGEMENT METHOD, COMMUNICATIONS APPARATUS, AND SYSTEM - Disclosed are an area-limited self-organized wireless network management method, a communication apparatus, and a system. The method comprises a step of, when a communications apparatus which is entering the limited area receives area signals for indicating a specific area in which network nodes are located, determining by the communications apparatus whether the master node exists in the limited area; a step of, if it is determined that the master node exists, performing identity authentication with regard to the master node and letting the communications apparatus itself be a sub node by the communications apparatus; and a step of, if it is determined that the master node does not exist, letting the communications apparatus itself be the master node by the communications apparatus, wherein, the master node is in charge of entering of a new sub node and synchronization of shared secret keys between the network nodes. | 05-08-2014 |
20140219262 | WIRELESS NETWORK AREA LIMITING METHOD AND SYSTEM BASED ON NEAR FIELD COMMUNICATION - Disclosed are a wireless network area limiting method and a wireless network area limiting system based on NFC. The wireless network area limiting method includes a step of adopting a plurality of first NFC hot spot sensors to seamlessly define a limited area having any shape; a step of periodically generating and transmitting an area secret key by a first central control part respectively connected to the plurality of first NFC hot spot sensors; and a step of conducting handshake with the first central control part by a WLAN user equipment, which has a NFC function and is located in the limited area, based on the area secret key received by the WLAN user equipment, so that the first central control part establishes area-limited network communications in the limited area. | 08-07-2014 |
20140241207 | METHOD AND APPARATUS FOR DISCOVERING NETWORK NODE - A method and an apparatus for discovering a node in a wireless self-organized network are disclosed. The method comprises the steps of determining, by nodes in the network, a unified node discovery channel based on unified information provided by a trusted third party; and finding the node based on the unified node discovery channel. According to the node discovering method, a node can be discovered rapidly, and the time for discovering a node can be reduced. | 08-28-2014 |
20150029959 | METHOD AND SYSTEM FOR ALLOCATING RADIO CHANNEL - A method and a system for allocating a radio channel are disclosed. The method includes the steps of determining one or more priority radio channels exclusively for transmitting priority data; determining whether there is a condition of allocating the one or more priority radio channels in an organized wireless group (OWG); and allocating one of the one or more priority radio channels, when the one or more priority radio channels are empty. | 01-29-2015 |
20150089606 | AREA RESTRICTED NETWORK MANAGEMENT METHOD AND DEVICE AS WELL AS AREA KEY RECEIPT METHOD AND DEVICE - 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. | 03-26-2015 |
20150139124 | CHANNEL POWER ADJUSTMENT BASED ON POSITIONAL INFORMATION OF AREA RESTRICTED SELF-ORGANIZING SUBNETS - Disclosed is a channel power adjustment method and system based on positional information of plural self-organizing subnets in a restricted area. The method includes a first setting step of setting, based on the positional information of the plural self-organizing subnets, a positional priority for each of the plural self-organizing subnets; and a first adjustment step of adjusting, at least partially based on the positional priorities of the plural self-organizing subnets, a power of a first device in a first self-organizing subnet working in a first channel, satisfying a predetermined rule to a first power of the first channel. | 05-21-2015 |
