| 20130145159 | TERMINAL APPARATUS FOR TRANSMITTING OR RECEIVING A SIGNAL CONTAINING PREDETERMINED INFORMATION - A modem unit and the like receive packets sent from a base station apparatus and receives packets sent from other terminal apparatuses. A processing unit processes the received packets. For the packets received by the modem unit and the like from the base station apparatus, a private key complying with a public key cryptosystem is used for a digital signature, whereas a symmetric key complying with a symmetric key cryptosystem is used for data. For the packets received from the other terminal apparatuses, a symmetric key complying with the symmetric key cryptosystem is used for the digital signature. | 06-06-2013 |
| 20130156017 | TERMINAL APPARATUS FOR TRANSMITTING OR RECEIVING A SIGNAL INCLUDING PREDETERMINED INFORMATION - A reception unit periodically receives a packet signal from a base station apparatus in each of two or more subframes in a superframe formed by time-multiplexing the subframes. An analysis unit gives a priority order to a subframe receiving the packet signal from the base station apparatus based on the packet signal received in the reception unit. A processing unit preferentially processes the packet signal received in the subframe with a high priority order among the priority orders given in the analysis unit. | 06-20-2013 |
| 20130230173 | COMMUNICATION APPARATUS FOR TRANSMITTING OR RECEIVING A SIGNAL INCLUDING PREDETERMIND INFORMATION - A storage stores a common key table containing a plurality of kinds of common keys usable for the communications with other communication apparatuses within the same system, its own identification information, and an update key associated with the identification information. The transmitter transmits the identification information to a system management apparatus for managing the common key table used in the system, the identification information on the communication apparatuses within the system, and the update key associated with the identification information. An acquiring unit acquires, from the system management apparatus that has received the identification information, a common key table for use in update (updating common key table) encrypted using the update key associated with the identification information. A decryption unit decrypts the encrypted updating common key table by use of the update key stored in the storage. | 09-05-2013 |
