20140165191 | APPARATUS AND METHOD FOR DETECTING IN-VEHICLE NETWORK ATTACK - An apparatus for detecting an in-vehicle network attack, is configured to cumulatively count packets for each device that has a respective ID and is connected to an in-vehicle network bus. The apparatus is configured to cumulate a check value every time the packets are cumulatively counted to calculate a cumulated value, and determine that an attack is conducted when an average cumulated value obtained by dividing the cumulated value by a cumulative counted value does not exceed a first threshold value. | 06-12-2014 |
20140188253 | METHOD AND SYSTEM FOR REPROGRAMMING - The system for reprogramming a plurality of control units includes a first control unit and a second control unit connected by one CAN bus, and a diagnosing unit. The diagnosing unit includes a first controller configured to reprogram the first control unit and a second controller configured to reprogram the second control unit. The diagnosing unit is configured to perform bidirectional reprogramming for the first control unit and the second control unit while sharing information between the first controller and the second controller. | 07-03-2014 |
20140189621 | APPARATUS AND METHOD FOR MODELING CONTROLLER OF CAN BUS SIMULATOR - An apparatus and a method for modeling a controller of a CAN bus are provided. The apparatus for modeling a controller of a CAN bus includes a modeling device for modeling a communication unit of a controller of the CAN bus and for evaluating the communication unit in a configuration of a CAN bus topology of the CAN bus. The modeling device includes an evaluation item determiner for determining the evaluation item used for simulating the configuration of the CAN bus topology, a factor determiner for determining factors that affect the evaluation result of the determined evaluation items, and a circuit design device for designing the circuit configured to include the determined factors. | 07-03-2014 |
20150085645 | ETHERNET BACKBONE NETWORK SYSTEM FOR VEHICLE AND METHOD FOR CONTROLLING FAIL SAFE OF THE ETHERNET BACKBONE NETWORK SYSTEM - An Ethernet backbone network system for a vehicle and a method for controlling a fail safe of the Ethernet backbone network system enable high-speed and large-capacity data transmission between integrated control modules mounted in the vehicle, such that communication can be maintained through another alternative communication line when an error occurs in a specific communication line. The Ethernet backbone network system enables various kinds of integrated control modules mounted in the vehicle to perform large-capacity and high-speed communications, based on Ethernet communication, by connecting domain gateways of the integrated control modules through an Ethernet backbone network, and provides a fast fail-safe function so that domain gateways can perform communications through another communication line when an error occurs in a communication line between the domain gateways. | 03-26-2015 |
20150180840 | FIRMWARE UPGRADE METHOD AND SYSTEM THEREOF - A firmware transmission method through which a server transmits firmware, includes generating a secret key using a designated secret key generation function, encrypting original firmware using the secret key, encrypting the secret key using a public key of a reception terminal which is stored in advance, and generating a hash value by inputting the original firmware to a designated hash function, and encrypting the generated hash value using a private key of the server which is stored in advance, wherein firmware data including the encrypted original firmware, the encrypted secret key, and the encrypted hash value is transmitted to the reception terminal. Therefore, the firmware transmission method provides safe firmware upgrade. | 06-25-2015 |
20160099926 | METHOD OF SEQUENTIALLY AUTHENTICATING CAN PACKETS USING DIVIDED MACS AND APPARATUS FOR IMPLEMENTING THE SAME - A method of transmitting K messages using divided message authentication codes (MACs) in a controller area network (CAN) includes: generating a MAC using a first message and a specific MAC, performing a first operation with respect to j using j-th messages subsequent to the first message and a second MAC part of the generated MAC, performing a second operation with respect to j using a result of the performed first operation and a j-th subblock subsequent to a first MAC subblock among K MAC subblocks obtained by dividing a first MAC part of the generated MAC, transmitting the first message along with the first MAC subblock, and transmitting K-1 j-th messages in an order of j, each of the j-th messages being transmitted along with a j-th result of the performed second operation. | 04-07-2016 |
20160099939 | METHOD OF AUTHENTICATING CAN PACKETS USING MIXTURE OF MACS AND APPARATUS FOR IMPLEMENTING THE SAME - A method and apparatus for authenticating packets in a controller area network (CAN) are disclosed. The method includes transmitting messages using a mixture of message authentication codes (MACs) in a controller area network (CAN). In addition, a first MAC is generated using a first message and the first MAC is divided into a first MAC part and a second MAC part. A second MAC is generated using a second message and the second MAC is divided into a third MAC part and a fourth MAC part. A linear operation is performed between the second MAC part and the third MAC part to generate a first authentication MAC. The first message is transmitted with the first MAC part and the second message is transmitted with the first authentication MAC. | 04-07-2016 |
20160142303 | METHOD AND APPARATUS FOR PROCESSING A SOME/IP STREAM THROUGH INTERWORKING WITH AVB TECHNOLOGY - A method for processing a SOME/IP stream through interworking with Audio Video Bridging (AVB) in a server includes determining a transmission scheme for the SOME/IP stream through a SOME/IP service discovery procedure and generating an InitialEvent message and transmitting the generated InitialEvent message to a client according to the determined transmission scheme. If the determined transmission scheme is L2-Frame, the SOME/IP stream is transmitted through a layer 2 of AVB. Therefore, a SOME/IP stream, the QoS of which is guaranteed through interworking with AVB, may be provided. | 05-19-2016 |
