Recently interest in Internet of Things(IoT) has attracted significant attention at national level. IoT can create new services as a technology to exchange data through connections among a huge number of objects around the user. Data communication between objects provides not only information collected in the surrounding environment but also various personalized information. IoT services which provide these various types of data are exposed to numerous security vulnerabilities. If data is maliciously collected and used by an attacker in an IoT environment that deals with various data, security threats are greater than those in existing network environments. Therefore, security of all data exchanged in the IoT environment is essential. However, lightweight terminal devices used in the IoT environment are not suitable for applying the existing encryption algorithm. In addition, IoT networks consisting of many sensors require group communication. Therefore, this paper proposes a secure multicast scheme using the proxy re-encryption method based on Vehicular ad-hoc networks(VANET) environment. The proposed method is suitable for a large-scale dynamic IoT network environment using unreliable servers.

국내 인터넷뱅킹 환경은 Microsoft 사의 Internet Explorer(IE) 브라우저에 맞게 구축되어 있어 Linux나 FreeBSD 등과 같은 공개 운영체제 및 웹 브라우저에서는 인터넷뱅킹 서비스를 이용할 수 없었다. 이런 문제 해결을 위해, 본 논문에서는 먼저 SEED를 이용한 공개 소프트웨어 환경에서의 전자 지불 시스템을 위한 전자 서명 시스템을 개발한다. 국내 인터넷뱅킹은 현재 공인인증기관이 발행하는 공인인증서를 통해 인증 및 전자서명 검증이 이루어져야 하는데, 그에 맞춰 공인 인증서 유효성 검증 시스템을 분석 및 개발한다. 마지막으로 자체 개발한 웹 서버에서는 이미 가상 인터넷 뱅킹환경이 구축되어 있어 SEED가 포팅 된 모질라 환경을 가지고 있는 클라이언트에서는 인증서를 설치하여 기본 인터넷뱅킹 서비스를 가상으로 받을 수 있으며 인증서 인증 및 전자서명이 정상적으로 작동되고 있다는 것을 구현을 통해 확인했다.

급변하고 있는 비즈니스 환경에서 인터넷기업들은 비즈니스 특성상 유연하고 개방적이며 자율성을 강조하는 조직문화의 특징을 가지며, 시간과 장소에 구애받지 않는 유연한 스마트 업무환경으로 변화하고 있다. 이러한 인터넷 비즈니스 환경에도 불구하고 보안관리체계는 여전히 인터넷기업의 비즈니스 환경과 조직문화를 반영하지 못하고 있으며, 이로 인해 인터넷기업에서의 통제중심의 보안관리 방식은 한계에 부딪히고 있다. 따라서 본 연구에서는 인터넷기업의 비즈니스 환경과 조직문화의 특성을 고려한 보안관리의 연구를 위해 기업구성원 자율중심의 보안역할 항목을 설계하고 개발하였다. 본 연구결과는 민첩한 비즈니스 환경과 자율적인 조직문화의 인터넷기업에서 기업구성원 자율중심의 보안관리체계를 구현하고 운영하는데 활용될 것으로 기대된다.

This study analyzed the effects of consumer confusion on shopping fatigue and negative purchasing behaviors in an internet shopping environment. Further, the effects of shopping fatigue on negative purchasing behaviors were analyzed. The survey was conducted among consumers in their 20s and 40s in the Seoul metropolitan area who had experience of purchasing fashion products through internet shopping. A total of 392 questionnaire were analysis, with frequency, reliability, factor, correlation, and regression analysis completed using the SPSS statistics program. The results of the study showed that consumer confusion and shopping fatigue in internet shopping environment affected negative purchasing behaviors. First, consumer confusion comprised overload confusion, similarity confusion, and ambiguity confusion. It was found that overload confusion and similarity confusion significantly affected shopping fatigue. Second, shopping fatigue significantly affected negative purchasing behaviors, and an increased level of shopping fatigue result in, increased purchase delay and non-purchase behavior. Third, consumer confusion (overload confusion, similarity confusion, ambiguity confusion) significantly affected purchase delay behavior, while similarity confusion and ambiguity confusion significantly affected non-purchasing behavior.

The emergence of technologies like Big data analytics, Industrial Internet of Things, Internet of Things, and applicability of these technologies in various domains leads to increased demand in the underlying execution environment. The demand may be for compute, storage, and network resources. These demands cannot be effectively catered by the conventional cloud environment, which requires an integrated environment. The task of finding an appropriate service provider is tedious for a service consumer as the number of service providers drastically increases and the services provided are heterogeneous in the specification. A service broker is essential to find the service provider for varying service consumer requests. Also, the service broker should be smart enough to make the service providers best fit for consumer requests, ensuring that both service consumer and provider are mutually beneficial. A service broker in an integrated environment named Global Manager is proposed in the paper, which can find an appropriate service provider for every varying service consumer request. The proposed Global Manager is capable of identification of parameters for service negotiation with the service providers thereby making the providers the best fit to the maximum possible extent for every consumer request. The paper describes the architecture of the proposed Global Manager, workflow through the proposed algorithms followed by the pilot implementation with sample datasets retrieved from literature and synthetic data. The experimental results are presented with a few of the future work to be carried out to make the Manager more sustainable and serviceable.

Lately, electronic commerce through the Internet has been rising in attention. An important element in such commerce is EDI. EDI is mainly used with VAN but its use is not common due to the high cost of EDI transfer. Thus, only large corporations with frequent use of EDI are able U benefit from it, To smaller companies that have small usage, EDI is becoming a burden. Considering this fact as well as current changes within the enterprise environment, it is apparent that a new generation of EDI is required. To resolve the problems of VAN EDI, the proposed Internal EDI was implemented. Internet EDI deals with the use of the widely spread Internet instead of VAN. By using Internet EDI, it is possible to reduce the high cost that came when using VAN. There would be no extra transfer cost since transmission will be done through the Internet. Also, electronic commerce that is mostly used today between an individual and a company may grow to become a true electronic commerce between companies.

As a result of broadcasters' websites, there were more reports during the typhoon Bolaven/Tembin in 2012 than in 2002 and 2003. Checking related press releases of each broadcaster on NAVER, YTN reports are 3 times more than KBS. Considering great technology progress in the Internet and smart phone user environment compared to the past, it is thought to be rather regretful in that KBS has been the supervising broadcaster over Korean disaster. As a result of daily reports, the year 2002 typhoon Rusa was reported from the date of its arrival on Korean Peninsular to 3 days, but the information required to be provided for disaster prevention before its arrival was too scarce. 2003 typhoon Maemi was reported as many times as the 2002 typhoon, but its information was provided before its arrival. This is meaningful because the information provision was intended for disaster prevention unlike the past. In 2012, the number of weather forecast broadcast on the typhoon Bolaven/Tembin increased greatly compared to 2002 and 2003. This was also determined to be due to abundant information provided by broadcasters and the Internet portal sites as a result of great progress in Korea internet industry.
