  • Publication number: 20190028785
    Abstract: A wavelength routing SW is a large-scale optical switch device of a conventional technique, and it requires as many wavelength-tunable light sources as the number of input ports. For the wavelength-tunable light sources to achieve a stable oscillating operation across a wide wavelength range, a complicated control mechanism is necessary. This has been an obstacle in providing a large-scale optical switch device in terms of cost and circuit scale. A wavelength routing SW in the present disclosure includes N wavelength group generators, a splitting-selection unit, and MN tunable filters. Each wavelength group generator includes M fixed-wavelength light sources. Inexpensive general-purpose devices that require no control mechanism for wavelength tuning can be used as the fixed-wavelength light source. The channel loss in the optical switch device can also be reduced by using light sources with a limited narrow range of tunable wavelengths and the wavelength-dependent output port selecting function of an AWG.

  • Publication number: 20190007234
    Abstract: A relay device capable of preventing transmission of an improper message to one or more networks even if improper falsification is made to a program for executing relay processing. If one CAN controller receives a message, a gateway stores the received message in the message storage unit and also sends the message to the processing unit. The processing unit that received the message performs processing necessary for relay of the message by executing a relay program, and sends the message to be relayed to the CAN controller. The gateway compares the message before being sent from the CAN controller to the processing unit with the message sent from the processing unit to the CAN controller, to determine the properness of the message.

  • Patent number: 10110377
    Abstract: A communication system and key information sharing method which allows first and second communication devices to share key information and perform cryptograph processing. The monitoring device calculates hash value based on copy data of storage content of an ECU, and transmits a part to the ECU as confirmation information. The ECU further extracts a part from a value, obtained by removing confirmation information from hash value calculated by the ECU, and transmits part to the monitoring device as response information when the received confirmation information is included in the hash value calculated by the ECU. The monitoring device determines whether the received response information is included in hash value of the monitoring device or not. The ECU and monitoring device each use residual value, obtained by removing confirmation information and response information from hash value calculated by the ECU or monitoring device, for following cryptograph processing as a shared key.

  • Publication number: 20180255072
    Abstract: A communication device capable of detecting transmission of an improper message to a network. A CAN controller in the gateway transmits and receives a message attached with a priority level (ID) to/from an ECU through a communication line, and counts, by the consecutive block number counter, the number of transmitted messages that are consecutively blocked as a result of arbitration processing as the number of consecutive blocks and stores the number as the number of allowed blocks into an allowed block number table in the storage unit in association with a priority level attached to the message received at the communication line. Every time a message is received, the controller compares the number of consecutive blocks with the number of allowed blocks for this message, and detects abnormality if the number of consecutive blocks is larger than the number of allowed blocks.
