摘要： 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.

摘要： A rewrite detection system, a rewrite detection device and an information processing device can detect unauthorized rewrite to a program or data stored in a storage unit of the information processing device. A rewrite detection device generates a random seed and transmits it to an ECU and a server device. The ECU calculates a hash value using a predetermined hash function on the basis of the received random seed and the storage content of the storage unit, and transmits the hash value to the rewrite detection device. The server device transmits an expectation in response to an inquiry from the rewrite detection device. The rewrite detection device determines whether unauthorized rewrite to a program or data in the ECU has been performed or not in accordance with whether the expectation received from the server device and the hash value received from the ECU coincide with each other or not.

摘要： Provided are a rewrite detection system and an information processing device capable of reducing communication traffic between devices and processing time in each device. A rewrite detecting device generates a random seed and transmits the random seed to an ECU, the ECU calculates a hash value using a predetermined hash function, and transmits the hash value to a rewrite detecting device. The ECU decides a storage region serving among storage regions of the storage unit, and calculates the hash value. The rewrite detecting device determines whether the hash value received from the ECU is right or wrong, and determines whether or not fraudulent rewrite has been performed. The ECU designates a storage region which is apart from a storage region used as a previous hash value calculation target by a predetermined address as a storage region of a current processing target.

摘要： In a communication system, an in-vehicle relay device relays data between ECUs, which are each connected to a communication line in a vehicle, by communicating with each of the ECUs. Data received by a communication device from a server outside the vehicle is input to an out-of-vehicle relay device. Data to be transmitted by the communication device to the server is output to the communication device by the out-of-vehicle relay device. The out-of-vehicle relay device relays data between the server and the ECUs by passing data to and from the in-vehicle relay device. The out-of-vehicle relay device outputs, to the in-vehicle relay device, data input to the out-of-vehicle relay device, or associated data that is associated with data that was output. The in-vehicle relay device determines whether the relaying performed by the out-of-vehicle relay device is to be suspended, based on associated data output by the out-of-vehicle relay device.

摘要： An access restriction device as well as an on-board communication system and a method for communication restriction, which prevent outside leakage of information caused by unauthorized access of malicious programs to an in-car network. The communication between the in-car network of the vehicle and an external device is performed by a security controller. The security controller can perform addition or update of a program involving processing for transmission and reception of the information. The security controller performs processing for restricting access to information of the in-car network performed by program execution according to an access authorization level of each program and an access permission level of each type of information. The security controller restricts the transmission depending on the access authorization level of each program and the access permission level of each type of information in case of transmitting the information to the in-car network by the program execution.
