Recently, it is proved that contactless smart-card based RFID tags, which is used for proximity authentication, are vulnerable to relay attacks with various location-based attacks such as distance fraud, mafia fraud and terrorist fraud attacks. Moreover, distance bounding protocols have been researched to prevent these relay attacks that can measure the message transmitted round-trip time between the reader and the tag. In 2005, Hancke and Kuhn first proposed an RFID distance bounding protocol based on secure hash function. However, the Hancke-Kuhn protocol cannot completely prevent the relay attacks because an adversary has (3/4)$^n$ attack success probability. Thus, this paper proposes a new distance-bounding protocol for light-weight RFID systems that can reduce to (5/8)$^n$ for the adversary's attack success probability. As a result, the proposed protocol not only can provide high-space efficient based on a secure hash function and XOR operation, but also can provide strong security against the relay attacks because the adversary's attack success probability is optimized to (5/8)$^n$.

Export control was first triggered by international export control system at US led COCOM in 1949. Numerous international efforts such as NPT in 1969, ZC in 1970, NSG in 1978, AG in 1985, MTCR in 1987, Wassenaar Arrangement(WA) establishment in 1995 with 1990's the fall of the Berlin Wall, have been made since. The concept of export control has been changed from weaponry and parts export control to preventing or blocking weaponry, respective goods and relevant technology from the hand of troubled regions and non-state actors as terrorist groups; and the new concept is described as Nonproliferation Control. Extent of control items is not only limited to conventional weaponry, but also includes weapons of mass destruction(WMD) and even dual use items which can be used for production, development, usage or storage. Control items include all items defined by NSG, MTCR, AG, WA, and CMC-Opec. The 9.11 terror had a strong influence on international society. Effort to prevent WMD proliferation has now become the most important issue for international security. This study aims to suggest improvement points for nonproliferation law and its effective implementation, based on problem and limitation identification along with analysis of nonproliferation law and implementation examples by type. Furthermore for the purpose of national and global security, export control system on strategic items which are considered to be a key issue in South and North Korea relationship needs to be effectively managed. Recently, North Korea's missile and nuclear tests have been criticized globally; and the global society including respective countries as China and South Korea is striving to urge export control in line with the UN resolution.

In this paper, we propose abandoned object detection algorithm. When abandoned object was occluded other object, the existing methods cannot detect abandoned object because those methods are not able to estimate the location of abandoned object. In order to overcome this problem, the proposed algorithm extracts the corners around abandoned object. The detected corners are linked to center of abandoned object called by supporters. We can then estimate the location of abandoned object by using supporters. Therefore, the proposed algorithm can detect and estimate the location of abandoned object, when abandoned object is occluded by other object. For this reason, the proposed algorithm can be applied to intelligent surveillance system to prevent bomb terror, which disguises as luggage or box.

The exponential increase of malicious and criminal activities in cyber space is posing serious threat which could destabilize the foundation of modem information society. In particular, unexpected network paralysis or break-down created by the spread of malicious traffic could cause confusion and disorder in a nationwide scale, and unless effective countermeasures against such unexpected attacks are formulated in time, this could develop into a catastrophic condition. As a result, there has been vigorous effort and search to develop a functional state-level cyber-threat early-warning system however, the efforts have not yielded satisfying results or created plausible alternatives to date, due to the insufficiency of the existing system and technical difficulties. The existing cyber-threat forecasting and early-warning depend on the individual experience and ability of security manager whose decision is based on the limited security data collected from ESM (Enterprise Security Management) and TMS (Threat Management System). Consequently, this could result in a disastrous warning failure against a variety of unknown and unpredictable attacks. It is, therefore, the aim of this research to offer a conceptual design for "Knowledge-based Real-Time Cyber-Threat Early-Warning System" in order to counter increasinf threat of malicious and criminal activities in cyber suace, and promote further academic researches into developing a comprehensive real-time cyber-threat early-warning system to counter a variety of potential present and future cyber-attacks.

Considerable number of major countries have put great efforts to leverage the efficiency of power consumption using Smart Grid in order to resolve the critical issues with drastical growing demands regarding electricity, the crisis of environmental pollution and so on. There has been increasing number of researches to construct Smart Grid in Korea as well. The threats of cyber terror attacks which might cause national crisises in terms of economy and society have been climbing up because of the fact that Smart Grid employs bi-directional communications embedding the cyber threats from existing/legacy communication networks. Consequently, it is required to build concrete response processes including investigation and analysis on cyber breaches into Smart Grid. However, the digital evidence acquisition techniques do not suffice to be deployed in Smart Grid systems despite of the fact that the techniques, against cyber breaches into well-known networks, have been studied in plenty of time. This work proposes a novel digital evidence acquisition scheme appropriate to Smart Grid systems through intensive investigation of the evidence acquisition requirements in Smart Grid and the historical evidence acquisition methods.

Since IT technology grow rapidly, our ethic of consciousness has become big issue with adverse effect. Many scholar has discussed and tired to solve this problem, but it is still helpless to fix. Therefor in this paper, author will not suggest the solution, but will present model list of adverse effects and cases to prevent accidents. The model list of adverse effects, what author will present is about media addiction, harmful content, cyber-violence, right infringement, cyber terror and decision obstacle. This model list is made by primary and secondary survey. This model will show adverse effect of present day, but also will show future adverse effects that can be prevent. Through out this paper, this model list could use for education plan.

It has been happening to transfer not only the general information but also the valuable information through the universal Internet. So security accidents as the expose of secret data and document increase. But we don't have stable structure for transmitting important data. Accordingly, in this paper we intend to use network based Intrusion Detection System modules and detect the extrusion of important data through the network, and propose and design the method for investigating concealment data to protect important data and investigate the secret document against the terrorism. We analyze the method for investigating concealment data, especially we use existing steganalysis techniques, so we propose and design the module emphasizing on the method for investigating stego-data in E-mail of attach files or Web-data of JPG, WAVE etc. Besides, we analyze the outcome through the experiment of the proposed stego-data detection system.

As North Korea has a sufficient ability to attack our society's vulnerable computer network, various large-scale cyber attacks are expected to be tried. North Korea's cyber military strength is known a world-class level. The number of its cyber agents is increasing consistently. Recently North Korea's cyber attack has been made regardless of trick and target. But up to now North Korea's cyber attack is more of an exploration than a real attack. Its purpose was to check how fast Korea found a problem and recovered from it. In future, cyber attack that damages substantially is highly probable. In case of an attack against national infrastructure like traffic, financial and energy services, the extent of the damage will be great beyond imagination. In this paper, characteristics of recent North Korea's cyber attack is addressed in depth and countermeasures such as the enactment of cyber terror prevention law, simulation training enforcement, private and public cooperation system construction, cyber security infrastructure expansion, etc. are proposed.
