Abstract: The present invention relates to a device for detecting an attack on a vehicle network and a method thereof and is to provide to a device for detecting an attack on a vehicle network and a method thereof which accumulatively counts packets by each device (ID) connected to a vehicle network bus, calculates the accumulated value by accumulating an inspected value (S) whenever accumulatively counting packets and determines that an attack is occurred if the average accumulated value calculated by dividing the accumulated value by the accumulated counting does not exceed a first threshold value. For the purpose, in a vehicle network environment in which devices, having a priority for packet transmission, connected to a vehicle network bus include: a packet collection unit for collecting packets transmitted through the vehicle network bus; a packet counting unit for accumulatively counting the number of packets collected by the packet collection unit; an inspected value calculation unit for calculating an inspected value based on a time difference between packets having the same ID; an accumulated value calculation unit for calculating an accumulated value by adding the inspected value which is calculated by the inspected value calculation unit to the previous inspected value; an average accumulated value calculation unit for calculating the average accumulated value by dividing the accumulated value calculated by the accumulated value calculation unit by accumulated counting value by the packet counting unit; and an attack determination unit for determining the existence of attack based on the average accumulated value calculated by the average accumulated value calculation unit. [Reference numerals] (10) Packet collection unit; (20) Packet counting unit; (30) Inspected value calculation unit; (40) Accumulated value calculation unit; (50) Average accumulated value calculation unit; (60) Attack determination unit; (70) Control unit

Abstract: 생성행렬의천공에기초한암호화키를사용하는데이터암호화장치및 방법이개시된다. 본발명은리드-뮬러(Reed-Muller: RM) 코드의생성행렬로부터특정지점의열에위치하는비트값들을천공한후 천공된생성행렬을이용하여생성된공개키를통해메시지의암호화를수행함으로써, 생성행렬의구조가변경됨으로인해 RM 코드의구조에기반한제3자로부터의공격을방어할수 있어서, 기존의 McEliece 암호화시스템이특수한구조를갖는 RM 코드의생성행렬을그대로사용함으로인해서발생하는보안상의취약성을해소할수 있다.
