유럽 18개 국가의 표준제정기구가 회원으로 구성되어 있는 유럽 규격제정 위원회(CEN：Comite europeen de Normalisation 또는 European Committee on Standardization)는 유럽 내에서 시판. 사용되는 모든 제품이 만족해야 할 규격 또는 규제안(regulation)을 제정하는 일을 담당하고 있다. 이들이 제정하는 규격의 기본적인 내용은 국제규격이나 각 나라의 규격과 대동소이하지만 그 내용에 있어서 구체적인 제품을 지정하기 때문에 보다 세분화되어 있으며 상업적인 성격을 띈다는 측면에서 ISO, DIN. BS등의 국제표준규격과 성격을 달리한다고 할 수 있다 특히, 이 위원회에서 공동으로 제정된 사안은 각 회원국에서 수정 없이 그대로 국가 인증규격으로 사용하므로 산업계에서는 상당한 영향력을 지닌 기구라고 할 수 있다.(중략)

디지털운행기록장치(DTG)는 차량의 운행정보를 기록하고 저장하는 장치로, 여객 및 화물자동차에 의무적으로 장착되어 여러 실시간 운행기록을 수집하고 관리할 수 있도록 하고 있다. 대부분 버스, 택시, 화물차 등에 사용되며, 상용 자동차의 운전자를 인증하고 과도한 운행으로 인한 사고를 줄이는 데 중요한 역할을 한다. 본 연구에서는 기존의 국내 디지털운행기록장치 관련 지침 및 표준 사양의 보안 기술 관련한 내용을 살펴보고 더 나아가 문헌조사를 통해 발견된 디지털운행기록장치 데이터 보호 관련 기본적 보안원칙을 소개한다. 더불어, 디지털 포렌식을 위한 데이터 식별 방법에 대한 실험적인 시도 사례의 결과를 함께 소개한다.

In the Past, Trend of car security was Physical Something like doorlock system, and The Generation did not have skills connecting External devices. Through Car Development is up, that trend of car security Changed Physical Security to Intelligence Security. This Changes give a chance to hackers to attack this system. This System use CAN(Controller Area Network) Protocol which have three vulnerabilities. First, ID Spoofing, Twice, D - Dos Attack, Third, Android Application Injected Modern cars have many ECU(Electronic Control Unit) to control devices like Engine ON/OFF, Door Lock Handling, and Controlling Handle. Because CAN Protocol spread signal using broadcast, Hackers can get the signal very easily, and Those often use Mobile devices like Android or IOS to attack this system. if bluetooth signal is spread wide, hackers get the signal, and analysis the bluetooth data, so then They makes certain data to attack ECU, they send the data to ECU, and control ECU installed car. so I suggest that I will prevent this attack to make Auth system and prevent this attack in end of Android.

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.

WiBro(Portable Internet Service) is service being capable to provide a high data rate wireless internet access with Personal Subscriber Station under the stationary or mobile environment, anytime and any where. It will fill the gap between very high data rate wireless local area networks and very high mobility cellular systems. The security is an important point of WiBro providing high data and mobile wireless services. This paper proposes user authentication mechanism of WiBro wireless networks applied EAP-AKA authentication protocol. As a result of Wireless authentication based on EAP-AKA, this mechanism is capable to be used in WiBro-WLAN-3GPP interworking scenario as well as the WiBro authentication mechanism.

An efficient management system for parking lots and traffic monitoring in a metropolitan city is a very important issue, which is tightly closed to qualify of life. While a residential permit parking program has been contributing to resolve the lack of parking places, there has been no autonomous authentication system due to no apparent entrance gate and smallness of each parking zone. In this paper, we propose and implement an authentication system for residential permit parking lot using wireless sensor networks, which is cost-effective and even no need for additional managing person. Through the experimental evaluation, we analyzed relationship between the life time of sensor nodes and the various values of sleep periods to minimize power consumption of the nodes, and also showed that the difference of luminance sensed by each sensor node is at least 45 or bigger between when the parking place is occupied or not, resultingly it can be used to decide whether a parking place is occupied or not by simply detecting the change of luminance sensed.

With the development of IT Info-Communications technology, the vehicle with a combination of wireless-communication technology has resulted in significant research into the convergence of the component of existing traffic with information, electronics and communication technology. Intelligent Vehicle Communication is a Machine-to-Machine (M2M) concept of the Vehicle-to-Vehicle. The Vehicle-to-Infrastructure communication consists of safety and the ease of transportation. Security technologies must precede the effective Intelligent Vehicle Communication Structure, unlike the existing internet environment, where high-speed vehicle communication is with the security threats of a wireless communication environment and can receive unusual vehicle messages. In this paper, the Vehicle Identification number between the V2I and the secure message communication protocol was proposed using hash functions and a time stamp, and the validity of the vehicle was assessed. The proposed system was the performance evaluation section compared to the conventional technique at a rate VPKI aspect showed an approximate 44% reduction. The safety, including authentication, confidentiality, and privacy threats, were analyzed.

The integrity assurance of recorded video by car black boxes are necessary as the car black box is becoming more popular. In this paper, we propose a video data integrity assurance scheme reflecting the features of car black box. The proposed method can detect any kind of deletion, insertion, modification of frames by cyclic chaining using inter block relation. And, it provides the integrity assurance function consistently even in cases of file overwriting because of no more free space in storage, partial file data lost. And non-repudiation is supported. Experimental results with a car black box embedded system with A8 application processor show that our method has a feasible computational overhead to process full HD resolution video at 30 frames per second in a real time.
