  • This paper traces the issue of key account management success which has regarded as a pressing concern of many companies' sales efforts at the organizational business-to-business context. Based on the extensive review of extant literatures, we introduced a theoretical framework that covers the antecedents and consequence of key account management success. We theorized the conditions under which organizational and relational factors influence the success of key account management approach. We endeavor to develop research propositions for each construct and provide necessary suggestions to isolate a platform for future empirical research. Beyond this span, an improved understanding from this framework will help developing policies for successful key account management approach.

  • In a cloud computing environment, a cryptographic service allows an information owner to encrypt the information and send it to a cloud server as well as to receive and decode encrypted data from the server which guarantees the confidentiality of shared information. However, if an attacker gains a coded data and has access to an encryption key via cloud server, then the server will be unable to prevent data leaks by a cloud service provider. In this paper, we proposed a key management server which does not allow an attacker to access to a coded key of the owners and prevents data leaks by a cloud service provider. A key management server provides a service where a server receives a coded public key of an information user from an owner and delivers a coded key to a user. Using a key management server proposed in this paper, we validated that the server can secure the confidentiality of an encryption key of data owners and efficiently distribute keys to data users.

  • The purpose of this research is to analyse the research subject in journal of Korean safety management and sciences. Total 1850 key words in 560 papers were analysed by the Pajek system which is one of well known social network analysis tool. Key words trend from 2008 to 2012 was examined. Then the relationship among each key words was visualized. There were five key words group which strongly connected among key words. The degree centrality, between centrality, proximity prestige on each key words were calculated to verify influence degree to other key words.

  • There have been several studies on the key issues in information systems (IS) management. This study replicates the Society for Information Management (SIM) survey done in U.S.A. to investigate the key issues in IS management in Korea. This survey focused especially on the professions in financial institutions. A three-round Delphi method was employed to collect the opinions of participants and obtain a reasonable level of consensus about the key IS management issues of financial institutions in Korea. The number one issue identified was top management support, followed by recruitment and development of IS human resources. This article also compares the key IS management issues of financial institutions and those of manufacturing industries in Korea.

  • 컴퓨터 보급의 증가와 인터넷의 발전으로 다양한 종류와 다량의 디지털 데이터들이 제작, 유포되고 있다. 디지털 컨텐츠는 기존의 아날로그 컨텐츠와 비교할 때 생성, 가공, 유통, 분배 등의 측면에서 많은 장점을 갖는 반면, 원본과 동일한 복사본을 쉽게 생성할 수 있는 특징 때문에 디지털 창작물에 대한 저작권 보호가 중요한 문제로 대두된다. 최근 디지털 컨텐츠 보호의 기술로 DRM(Digital Rights Management)이 사용되고 있으나 컨텐츠 유통 시 키 관리에서 취약성을 띄고 있다. 따라서 본 논문은 디지털 컨텐츠 보호 기술인 DRM을 분석하고 컨텐츠 유통의 키 관리 문제에 대한 개선책으로 $\ast$CDMS(CEK Distributed Management System)를 설계하여 이를 이용한 보다 안전한 키 관리 체계를 연구한다.

  • 본 논문에서는 WSN을 위한 위치 기반의 키 관리 기법에 대해서 제고한다. 기존의 위치 기반의 키 관리 기법들에 대해 알아보고 그 중 LDK (Location Dependent Key management) 기법을 집중적으로 파악하였다. 이를 통해 LDK 기법에서 고려하지 못한 통신 간섭 문제를 개선하기 위하여 그리드 정보를 활용한 키 생성 기법과 키 보정과정을 활용하는 기법을 제안하였다. 시뮬레이션을 통하여 보안성이 높은 환경에서 제안 기법이 기존의 LDK보다 접속율은 향상하였고 절충율은 감소하였음을 확인하였다. 또한, 육면체 형태의 AN 배치를 통해 네트워크 비용을 줄일 수 있음을 시뮬레이션을 통해 확인하였다.

  • With the paramount importance of key account management in business-to-business relationship, today companies are using this approach as a strategic weapon in their selling efforts targeted at the most important customers to solve their complex requirements with special treatment that eventually ensures both parties' financial and nonfinancial objectives. The aim of this paper is to investigate the level of key account management performance among the export-oriented readymade garments companies in Bangladesh with regards to company's experience in business, size of the company and key account serving capacity of the company. Using a questionnaire, data from 112 readymade garments companies in Bangladesh were collected and analyzed using descriptive analysis and ANOVA to test the level of key account management performance. Results show that the level of key account management performance by the garments companies did not vary by the company's experience in business and size of the company respectively. In contrast, the level of key account management performance was found to be different concerning high, medium, and low customer service capacity. Apparently, companies with big number of customers show better performance than companies with small number of customer. Implications for this study are discussed along with suggestions for future research avenues.

  • This paper presents an achievable secure videoconferencing system based on quantum key encryption in which key management can be directly applied and embedded in a server/client videoconferencing model using, for example, OpenMeeting. A secure key management methodology is proposed to ensure both a trusted quantum network and a secure videoconferencing system. The proposed methodology presents architecture on how to share secret keys between key management servers and distant parties in a secure domain without transmitting any secrets over insecure channels. The advantages of the proposed secure key management methodology overcome the limitations of quantum point-to-point key sharing by simultaneously distributing keys to multiple users; thus, it makes quantum cryptography a more practical and secure solution. The time required for the encryption and decryption may cause a few seconds delay in video transmission, but this proposed method protects against adversary attacks.

  • Purpose - This study traces the determinants of key account management performance in the garments industry in Bangladesh. The key account management approach involves significant challenges for marketers to manage their strategically important customers and use this approach as a strategic weapon in their selling efforts. This study examines three categories of determinants of key account management performance including operational variables, organizational variables, and relational variables by exploring data from 100% export oriented readymade garments companies in Bangladesh. Research design, data, and methodology - Data were collected from 30 readymade garments manufacturers, considering a company as a unit of analysis. Using the data, instrument validity and reliability and, subsequently, data normality were examined using the Statistical Package for the Social Sciences (SPSS) software to isolate the important determinants of key account management performance. Results - The instruments are reliable and the data are reasonably normal. Conclusion - The study explored and validated the adapted instruments of various operational, organizational, and relational antecedent factors of key account management performance, most of which were thus far ignored.
