With the development of cloud computing and widespread availability of mobile devices, outsourcing computation has gotten more and more attention in cloud computing services. The computation of bilinear pairing is the most expensive operation in pair-based cryptographic schemes. Currently, most of the algorithms for outsourcing bilinear pairing have small checkability or the outsourcers need to operate expensive computations. In this paper, we propose an efficient algorithm for outsourcing bilinear pairing with two servers, where the outsourcers can detect the errors with a probability of 1 if the cloud servers are dishonest, and the outsourcers are not involved in any complex computations. Finally, the performance evaluation demonstrates that the proposed algorithm is most efficient in all of fully verifiable outsourcing algorithms for bilinear pairing.

The goal of this paper is to offer a quantitative decision model using Quality Function Deployment(QFD). We consider the factors outsourcing that affect the benefits of the organization and the fifth alternatives that were selected to be considered for outsourcing as customer requirements and technical attributes in QFD. For selecting the outsourcing system, we compute the priority considering interdependencies among alternatives. Thus this paper propose a decision model, which uses the quality function deployment to help practitioners set priority and users in structuring the outsourcing problems.

Recently, with increasing interest in the subject of interfirm relationship mechanism, some information systems researchers point out that existing outsourcing theories are limited in explaining the choice of governance mechanisms in interfirm relational exchanges. Recognizing the importance of trust-commitment, this study focuses on the relationship of between control mechanism and commitment. Especially the role of trust as mediator is mainly researched. A mediation model was suggested on the basis of theoretical linkages from prior relevant studies. The research model was empirically tested with 73 IS outsourcing projects. The findings have significant impactions for further research and practice. Findings are as follows: First, outcome control, process control, social control had positive effects on trust and commitment. Second, inter-organizational trust played as a partial mediator on the relationship between control mechanisms and commitment. Based on these findings, the implication and the limitation of the study were presented including some directions for future studies.

IT관리의 효율성과 효과성을 높이기 위한 방안으로 IT서비스관리(IT service management)의 중요성이 점증되고 있으며 아웃소싱 서비스 성과를 높이기 위하여 IT서비스 방법론 도입이 활발하게 진행되고 있다. 본 연구는 IT 아웃소싱 서비스 성과향상을 목표로 도입된 ITIL기반 IT서비스관리 시스템의 효과를 사례를 통하여 분석하였다. 연구결과 IT서비스 관리 시스템 구축이 정보시스템의 시스템 품질, 정보 품질, 서비스 품질에 직접적인 영향을 미치고 있으나 최종사용자의 시스템 사용(use) 및 사용자 만족도에는 직접적인 영향을 미치지는 못하는 것으로 나타났다. 본 연구는 ITIL기반 IT서비스 관리 시스템 구축 성과와 그 영향 범위를 탐색함으로써 IT서비스프로세스 연구를 위한 발견들(findings)을 정리하고 향후 이를 도입하고자 하는 기업의 효과적인 IT서비스관리 체계 구축을 위한 지침을 제공한다.

This study explores a model of partnership to the success of outsourcing CTI(computer telephony integration) based customer service centers of a telecommunication service company. The motivation of the study is to extend the research on IT outsourcing to IT-enabled BPO of customer service centers as a specific IT outsourcing practice. Previous research on IT outsourcing partnership and success is reviewed for developing an a research model of IT-enabled BPO. This model is proposed based on the previous partnership success models in information systems research. The results of the study confirm major factors related to successful IT-enabled BPO in previous research. Especially, the specificity of a contract and strategic collaboration in partnership are found to be influential on the success of IT-enabled BPO.

This paper considers probable determinants of the application software outsourcing costs and focuses on the service level agreement (SLA) influence. Recently, outsourcing clients and vendors have contracted SLA and tried to reflect them on outsourcing prices. While application software maintenance has been one of the most frequently outsourced functions, its cost did not reflect the service level requirements by the client. This paper empirically shows that the service urgency requirement on SLA increases the maintenance programmers' effort and thus increases the vendor's cost. This result can be used by vendors for program allocation purposes.

This study examines control types of IS outsourcing project management focusing on two sets of questions: What control types are implemented during IS outsourcing projects? How various control types affect the performance of IS outsourcing projects. In order to meet these objectives, four control types are developed using typology-approach: dynamic, contract-oriented, partnership-oriented, and passive. And then four control types are identified based on taxonomy-approach using cluster analysis from 66 projects: dynamic, contract-oriented, passive, and middle. The result shows that the derived taxonomy-types are similar to the typology-types except partnership-oriented type. The result also indicates that dynamic and contract-oriented types are in the highest performance, while passive type is in the least performance.

Growth in the outsourcing market signals that firms of all sizes believe outsourcing will ultimately deliver many benefits and conveniences. But there are not many firms satisfied with the results of outsourcing. What is more, previous researches were fragmentary analyses focused on specific variables of outsourcing such as sourcing decisions, partnership rather than comprehensive analysis. Thus, they could not propose general systematic methodologies applicable to the real situation. To solve these problems, we developed an integrated theoretical framework that considered both contract with the hard side and trust with the soft side from a contingency viewpoint and tested this model using 143 data of Korean companies executing outsourcing. In addition, we examined how situational factors(outsourcing task complexity and outsourcing management competence) affects each path in the research model. The results of this study are as follows. First, it was proved the theory that trust is not a substitute for contract but its complement. Previous empirical studies on outsourcing success factors were focused on the establishment of successful partnership on the assumption that trust can replace contract in many situations. According to the results of our empirical analysis, however, contract and trust were in a mutually complementary relation with each other and their emphasis was different. Furthermore, different from previous researches, it was found effective to use trust as a supplementary tool and contract as a main means in outsourcing management strategy. Second, this study provided an integrated view that sees both contract and trust from a contingency viewpoint in theoretically reestablishing the relationship between contract and trust. Previous researches leaned to specific variables or theory-centered fragmentary analysis, but this study proposed a more practical and integrated research model and tested its effectiveness. Based on the results, with the model, decision makers are expected to scrutinize outsourcing situation more closely and to have a practical insight to the situation. Third, it was found that contract mechanism and trust building do not have a direct effect on outsourcing performance but relationship management intensity mediates the effect of contract mechanism and trust building. This is considered significantly meaningful to outsourcing partners who have believed that outsourcing would be successful if a contract is made properly or trust is built. Lastly, the path from trust building to relationship management intensity was moderated by informed buying, as the path coefficients from trust building to relationship management intensity varied by the degree of informed buying competence.
