摘要： Provided are a communication system and a communication device that allow a reception node to estimate delay time, a generation time point or the like of a message. A delay time estimation part in an ECU determines whether a message received by itself is transmitted in sequence with another message without being provided with time information by a transmission node. If the received message is transmitted in sequence with another message, the received message may be delayed due to arbitrary processing. Thus, the delay time estimation part checks the priority of one or more sequential messages preceding the received message, and estimates delay time of the received message occurring due to the arbitrary processing in accordance with the priority of each message. A generation time point estimation part estimates the time point when the received message is generated by an ECU, based on the delay time estimated.

摘要： In the on-vehicle communication system according to the present embodiment, a plurality of on-vehicle communication devices are classified by a plurality of security levels, and a common key is specified for each of the security levels. Each of the on-vehicle communication devices stores a common key according to a security level of itself, adds an authentication code generated by using the common key to a message to be transmitted and determines whether or not an authentication code added to a received message is authorized by using the common key. The on-vehicle communication control device stores common keys of respective security levels, determines whether or not a authentication code added to a received message is authorized by using the corresponding common key and, if determining that the authentication code is not authorized, makes a report to the on-vehicle communication device that does not store the common key used for this determination.

摘要： A communication system and a comparison method for securing a communication path for a legitimate user via a terminal apparatus (“TA”). A vehicle-mounted communication device (“VMCD”) transmits a device ID identifying the VMCD to a TA, acquires a terminal ID from the TA, and transmits the device ID and the terminal ID acquired from the TA to a central apparatus. The TA transmits a terminal ID identifying the TA to the VMCD, acquires a device ID from the VMCD, and transmits the terminal ID and the device ID acquired from the VMCD to the central apparatus. The central apparatus receives a device ID and a terminal ID transmitted from the VMCD and a device ID and a terminal ID transmitted from the TA, and compares the device ID and the terminal ID received from the VMCD with the device ID and the terminal ID received from the TA.

摘要： Provided are a communication control device and a communication system capable of detecting message transmission in the case where an invalid device transmits a message to a common communication line. A monitoring device decides a reference time point t0 for periodical message transmission by an ECU, decides multiple scheduled transmission time points t1, t2, . . . obtained by adding a period corresponding to an integer multiple of a transmission cycle T of a message to the reference time point t0, and decides that a predetermined period including each of the scheduled transmission time points is a permission period for message transmission. The monitoring device determines whether or not a detected message on a CAN bus has been transmitted during the permission period. If determined that transmission of an invalid message is not permitted, the monitoring device performs processing of causing the ECU which receives the message to discard the message.

摘要： 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.

摘要： A connection detection apparatus in includes a gateway to which communication lines are connected, and which detects whether an unauthorized communication device has been connected to the communication lines. The gateway samples a signal several times from each of the communication lines, and generates waveform information, such as an eye pattern in which the waveforms are superimposed on one another. Furthermore, the gateway has stored therein normal waveform information, such as a mask generated based on the eye pattern at normal times. The gateway compares the generated waveform information with the stored waveform information, and recognizes that the waveform information is abnormal if it does not sufficiently match the normal waveform information. If the waveform information is abnormal, it is determined that an unauthorized communication device has been connected to one or more of the communication lines.

摘要： An unauthorized message in an in-vehicle network is more accurately detected. A detection device includes: a monitoring unit configured to monitor, as target messages, an authorized message being periodically transmitted and the unauthorized message in the in-vehicle network, and monitor a reference message being periodically transmitted; a calculation unit configured to, based on a monitoring result of the monitoring unit, calculate a time difference between a time corresponding to a transmission time of the target message and a time corresponding to a transmission time of the reference message; and a detection unit configured to, based on the time difference calculated by the calculation unit, perform a detection process of detecting the unauthorized message.
