With the development of new ICT technology, new technologies are being applied to automobiles. The smart key for vehicles is also a device to which ICT new technology is applied. Therefore, a cyber-hacking attack against a smart key of a vehicle is possible. The cyber attack on the smart key can cause an abnormal control of the vehicle. Vehicle control can lead to vehicle hijacking and vehicle control risks. In this paper, we analyze the vulnerability of smart key for vehicle. Analyze cyber attacks against smart keys in vehicles. Then, we conduct real hacking attacks on smart keys for vehicles and propose countermeasures. We conduct a hacking attack against the smart key for vehicle that has devised countermeasures and analyze countermeasures against cyber attack security. This paper will contribute to the prevention of vehicle deodorization and to the safety of the people.

With the development of new ICT technology, smart keys for vehicles are terminals with ICT technology. Therefore, when the vehicle and the smart key communicate with RF, a cyber hacking attack is possible. Cyber-attacks on smart keys can pose a threat to vehicle theft and vehicle control. Therefore, it is necessary to study hacking attacks and vulnerabilities of smart keys for autonomous vehicles. In this paper, we analyze the cyber attack case of RF communication for vehicles and smart keys. In addition, a real RF cyber attack on the smart key is performed, and the vulnerability of radio wave replication in the same frequency band is found. In this paper, we analyze the vulnerability of RF communication between vehicles and smart keys, and propose a countermeasure against cyber security. In the future, plans to strengthen cyber attacks and security through the popularization of autonomous vehicles will become basic data to protect human and vehicle safety.

Along with the strengthening vehicle environmental regulations and the growing needs for the energy consumption reduction technology, the researches on the engine idle stop system, have been briskly carried out around the automobile manufacturers before the development of alternative energy. Furthermore, there is a movement to disseminate the environment friendly idle stop system by combining the system to the generalized smart key system to not only increase purchasing but also provide the convenience and save the energy as well. In this paper, we designed and implemented the idle stop system algorithm for the aftermarket smart key system with the OBD-II interface. The implemented start stop system is capable of controlling two independent systems, the smart key system and intelligent idle stop system, on a single ECU. In addition, the implemented start stop system standardizes the communication interface with the vehicles to reduce the time required for installing the start stop system to the various vehicles, and satisfies every standard response time limit for the vehicle status request signals.

최근 스마트 카가 발전하면서 물리적 키에서 스마트 키로 차량용 키도 변화하고 있다. 이에 따라 스마트 키에 대한 해킹 위협도 증가하고 있으며 스마트 키의 보안은 점점 중요해지고 있다. 기존의 스마트키는 자동차 시스템이 부팅 된 후에 데이터 값을 비교하는 방식으로 사용자 인증을 진행한다. 이러한 방식은 시스템이 이미 부팅된 상태이므로 여전히 해킹의 위협이 존재한다는 점에서 안전하지 않다. 본 연구에서는 이를 개선하기 위해 Python 코드 분리 기술과 APK 바이트 코드 분리 기술을 자동차 부팅 코드와 엔진 APK의 바이트 코드에 적용하는 방법을 제안한다. 제안 기술이 적용되지 않은 APK와 적용된 APK를 리패징하여 해킹에 대한 본 연구의 안정성을 검증하였다.

Because many of the FOB key, anti-collision algorithm for a seamless multi-access is applied to the smart-key system. In this paper, we have designed and implemented improved anti-collision algorithm that dramatically reduces the communication response time required in the user authentication process immediately after by dynamically changing the order in which the request of the user ID as the user ID on immediately before in the smart key system for vehicles that use many of the FOB key. In order to evaluate the performance of the system the improved anti-collision algorithm is applied, we show the behavior of the algorithm implemented in the state actually mounted on the vehicle and verify that communication response time required for many of the FOB key was reduced by about 33% compared to existing algorithms.

Using sensor devices applied to various objects will be needed wireless network that it is easy to install in them. Tiny devices configured to processor that bas comparatively low computing ability are inappropriate to use devices that are wireless LAN, etc. In result, network devices needed to not only have simple communication protocol, but have Plug and Play function that it works as soon as it connects without installing any device driver. it also will industrially have both low power and low cost because of mobility of it. From IEEE 802.11 standard, WPAN(Wireless Personal Area Network) included in LAN is being developed by WPAN WG(Working Group) on area with low power consumption and low complexity. In addition to, it is standardizing MAC and PRY of the standard that is expected to wirelessly communicate within 10m. WPAN will be used generally in the more near future because of both low power and low cost of Zigbee. In this paper we designed zigbee based user authentication module for a automotive smart-key system.
