Security has become a major concern for many real world applications for wireless sensor networks. Usually, all these approaches are based on well known cryptographic algorithms. At the same time, performance analyses have shown that the applicability of sensor networks strongly depends on effective routing sessions or energy aware wireless communication. Based on our experiments, we provide some analyses and considerations on practical feasibility of such cryptographic algorithms in sensor networks.

As the expansion of enterprise scale and the increase of staff, the amount of terminal is increasing as well. It is very difficult to the system manager of traditional data protection scheme to manage and maintenance for the large number of terminals. This problem can be solved by desktop virtualization, which use traditional security problems still exist and new security problems occur at the same time. Using desktop virtualization, it needs a method of automatic security protection. In this paper, the desktop virtualization security requirements are discussed.

This study aims to review Russia's annexation of Crimea from a maritime security perspective. Based on a comprehensive analysis of Russia's national security perception, this study analyzed Russia's maritime security strategy and the security importance of the Black Sea and the Sea of Azov, and reviewed the annexation of Crimea from a maritime security perspective. The main argument of this study is as follows. Russia's annexation of Crimea was necessary for the successful fulfillment of Russia's maritime security strategy in the Black and Azov Seas. Russia's annexation of Crimea guarantees the activities of the Black Sea Fleet militarily from a maritime security point of view, secures a passage to the Atlantic Ocean to counter NATO's expansion. From a economic security point of view, Russia's annexation of Crimea was based on the strategic considerations to secure influence within the Black Sea economic bloc which guarantees stable production and transportation of natural resources and shipping.

In this paper, an Information Security protocol in LLC/MAC Layer Architecture is discussed. This paper examines the security Vulnerability and threats, the security Service required to protect these threats, and architectural considerations of security protocol in IEEE 802 LAN architecture. To provide an Information security service, an information security protocol(SP2 : Security Protocol 2) PDU construction with LLC/MAC service primitives is suggested. To construct the SP2 protocol, the ECB, CBC mode of DES algorithm and DAA(Data Authentication Algorithm) of FIPS is used. The SP2 protocol suggested in this paper provides data origin authentication, data confidentiality, data integrity service.

Ministry of National Defense plans to harness AI as a key technology to bolster overall defense capability for cultivation of an advanced strong military based on science and technology based on Defense Innovation 4.0 Plan. However, security threats due to the characteristics of AI can be a real threat to AI-based defense information system. In order to solve them, systematic security activities must be carried out from the development stage. This paper proposes security activities and considerations that must be carried out at each stage of AI-based defense information system. Through this, It is expected to contribute to preventing security threats caused by the application of AI technology to the defense field and securing the safety and reliability of defense information system.

Many researches have proposed key management schemes for Smartgrid System. However, previous studies lack the proper considerations for availability and device security. In this paper, we build up cryptographic security improvement for robust Smartgrid Systems. In addition, we propose a public-key management and hash function architecture for robust Smartgrid Systems which supports reduces the number of key and Secure Device in AMI network environments.

Owing to the change of economic trends, the importance of the tourism industry is growing more and more. In particular, the number of foreign tourists continues to increase and the type of tourists is being changed into FIT (Foreign Independent Traveler). Therefore it is an important issue to provide the effective information to foreign tourists. To solve these problems, a variety of IT technology is being used in the tourism information systems. Especially the location based tour information service is being emerged. This kinds of tourism information service is a type of LBS (Location Based Services). But if the security of the location based tourism information service is not guaranteed, it can lead to many dangers. In this paper, the trends of location based tourism information service are surveyed. Also the security threats and countermeasures for the location based tourism information service are analyzed. This paper suggests secret considerations for the location based tourism information service.

The increasing demand of users for various wireless communication services has lead to the development with uniting co-existence of different and wireless networks. Each one of the these wireless networks has its own unique characteristics, as compared to other networks. An integrated security mechanism is one of the key issue in the open wireless network. To realize overall security mechanism in open wireless architecture, we should provide practical workable framework for the realization of the integrated security challenges. In this paper, we analysed integrated security platform and considerations based on the security concept.

Purpose: Cloud-computing technology has several advantages, including maintenance, management, accessibility, and computing power. A greenhouse-control system utilizing these advantages was developed using a private cloud-computing system. Methods: A private cloud needs a collection of servers and a suite of software tools to monitor and control cloud-computing resources. In this study, a server farm, operated by OpenStack as a cloud platform, was constructed using servers, and other network devices. Results: The greenhouse-control system was developed according to the fundamental cloud service models: infrastructure as a service, platform as a service, and software as a service. This system has four additional advantages - security, control function, public data use, and data exchange. There are several considerations that must be addressed, such as service level agreement, data ownership, security, and the differences between users. Conclusions: When the advantages are utilized and the considerations are addressed, cloud-computing technology will be beneficial for agricultural use.

The purpose of this study is to profile actual conditions of personal information protection systems operated in overseas countries and examine major considerations of personal information that security service providers must know in the capacity of privacy information processor, so that it may contribute to preventing potential occurrence of any legal disputes in advance. Particularly, this study further seeks to describe fundamental idea and principle of said Personal Information Protection Act; enhancement of various safety measures (e.g. collection/use of privacy data, processing of sensitive information/personal ID information, and encryption of privacy information); restrictions on installation/operation of video data processing devices; and penal regulations as a means of countermeasure against leakage of personal information, while proposing possible solutions to cope with these matters. Using cases among foreign countries for this study.
