On our way to switching from single-server to multi-server authentication, one of the great challenges is to design a secure and computationally efficient multi-server authentication protocol. Multi-server Authentication (MSA) relieves the user of separate and individualized registration procedures from various service providers in a network. Following MSA paradigm, a user gets registered from a trusted authority first, and then the former may benefit itself from any service being offered by any service provider without registering again, engendering overhead efficiency. Another objective for switching towards multi-server architecture was to relieve the user of maintaining multiple passwords as much as the number of servers. A robust MSA architecture makes the access of sever-oriented network services not only convenient but also readily available for users. The remote internet authentication often entails the type of multiserver authentications, which further underscores the need of MSA protocol’s efficiency and robustness against threats. The service providers in an MSA-based network authenticate and verify the users on the basis of credentials provided by Registration Centre (RC) to the users during registration phase. In traditional MSA protocols, service providers consult online RC for verifying the user’s authenticity after receiving a login request. Besides, we witness MSA protocols where RC is bypassed during mutual authentication between user and service provider. The latter class of schemes takes less communicational cost and eliminates few bottlenecks, perceptibly, due to bypassing trusted RC from mutual authentication phase. The research academia came up with many authentication protocols lately, to enhance security and minimizing communicational overhead. However, the presented solutions are costly due to employing expensive bilinear operations, on the first hand. Besides, there are light-weight MSA protocols as well, nevertheless bearing many other drawbacks making those protocols unfit for practical implementations. We address these problems by presenting a novel multi-server authentication protocol framework that is not only efficient but also free of the hassle of key management and distribution problems. The protocol framework comprises a blend of the usage of selected crypto-primitives, messages and participating entities in such a way that leads to overall efficiency and achieves the security objectives as well. In this dissertation, we present state-ofthe-art review on MSA-based protocols and then propose corresponding protocols to address the above limitations. Our proposed work not only contributes a light-weight multi-server authentication protocol framework that could establish mutual authentication without RC engagement, but also improves upon many MSA schemes (Trusted and Non-trusted environment) to enhance security and reduce communication or computational delay for establishment of an authenticated session key between user and server. To prove the security claims, the formal security analysis is performed for each protocol and the results are also validated and verified using automated simulation tools.

PENGARUH MOTIVASI DAN KEPUASAN KERJA PEGAWAI TERHADAP KUALITAS LAYANAN ADMINISTRASI AKADEMIK DI FTIK IAIN PALU

This study aims to determine: 1) The effect of employee work motivation on the quality of academic administration services in FTIK IAIN Palu. 2) The effect of employee job satisfaction on the quality of academic administrative services in FTIK IAIN Palu, 3). Effect of Motivation and Job Satisfaction of employees on the Quality of Academic Administrative Services in FTIK IAIN Palu. This research uses a quantitative approach with questionnaire data collection techniques, questionnaires, interviews, observation, and documentation. While the data analysis technique used is the classic assumption test using normality, multicollinearity, and heteroscedasticity tests. Research Results Show There is a significant influence on the work motivation of administrative employees on the quality of Academic Administration Services by 17.4%. There is a significant effect of Employee Job Satisfaction on Academic Administration Service Quality of 51%, and There is a significant effect of motivation and level of employee job satisfaction the quality of academic administration services is 80.3%. Keywords: motivation, satisfaction, administrative services

Bilateral Effect of Foreign Direct Investment and Human Resource on Socio-Economic Development of Pakistan

The Foreign Direct Investment (FDI) as a package of capital, knowledge and skills has been getting popular for the last three decades among the developed as well as the developing countries. As regards its impact on the socioeconomic development of the host country, many developed and developing countries liberalized their economies and adopted radical policies to attract the FDI. Pakistan is one of such countries that took the FDI oriented stance in late 1980s. Among the multiple determinants of the FDI, the human capital got much importance in the literature with the passage of time. From the other side, the impact of the FDI on the human capital of the host country is also evident in the literature. This bilateral relationship between the human capital and the FDI may result in the socioeconomic development of the host country. The human capital is one of the social indicators and its formation owing to the FDI inflow is the very social development. The FDI may influence the economic development of the host country with the help of capital, payment of taxes, provision of jobs, and improvement in balance of payments. This social and economic development due to the bilateral relationship between the human capital and the FDI is the context dependant one. In the Pakistani context such nexus has not been studied fully. The studies that touched upon it partially are a few also with the conflicting results. This dissertation analyzes this very nexus empirically for Pakistan with the help of using the country level time series data during the period from 1971 to 2005 through four models. First of all it examines the human capital as determinant of the FDI. Then it investigates the impact of the FDI on the human capital. At the third stage it explores as to how FDI inflow influences the economic development in Pakistan. Finally, it studies the impact of the human capital on the economic development of Pakistan. This study also analyzes the trend and the pattern of the FDI flow in Pakistan and theoretically it identified the factors impeding the FDI xinflow. As for the data analysis, the bound testing approach to the cointegration within the framework of the Autoregressive Distributed Lag (ARDL) was used. The study concludes that: The human capital has a significantly positive impact on the FDI flow in Pakistan; The FDI does not influence the human capital formation at the macro level; The FDI is strongly instrumental in the economic development; and also the human capital leads to economic development of Pakistan. The factors impeding the FDI flow in Pakistan are: the perception among the foreign investors regarding the poor implementation of the policies in Pakistan; the poor law and order situation; the ongoing terrorism; weak economic conditions; the nuclear test of May 1998; inconsistent and short-term policies about investment and industrialization; various types of obstacles for investors regarding approval; comparatively insufficient infrastructure; poor condition of the human capital; and tangled labor laws and the pro-labor policies. On the bases of conclusion, policy implications have been touched upon the attraction of FDI and the formation of the human capital in such a way as may result in the socioeconomic development of Pakistan.
