On Security Analysis of Recent Password Authentication and Key Agreement Schemes Based on Elliptic Curve Cryptography
Get PDFSecure and efficient mutual authentication and key agreement schemes form the basis for any robust network communication system. Elliptic Curve Cryptography (ECC) has emerged as one of the most successful Public Key Cryptosystem that efficiently meets all the security challenges. Comparison of ECC with other Public Key Cryptosystems (RSA, Rabin, ElGamal) shows that it provides equal level of security for a far smaller bit size, thereby substantially reducing the processing overhead. This makes it suitable for constrained environments like wireless networks and mobile devices as well as for security sensitive applications like electronic banking, financial transactions and smart grids. With the successful implementation of ECC in security applications (e-passports, e-IDs, embedded systems), it is getting widely commercialized. ECC is simple and faster and is therefore emerging as an attractive alternative for providing security in lightweight device, which contributes to its popularity in the present scenario. In this paper, we have analyzed some of the recent password based authentication and key agreement schemes using ECC for various environments. Furthermore, we have carried out security, functionality and performance comparisons of these schemes and found that they are unable to satisfy their claimed security goals
A Principal-Agent Explanation for Technology Transfer
Get PDFTechnology licensing and transfer is subject to problems of asymmetric information including moral hazard. This study explores the effects of informal governance, knowledge tacitness, and organizational receptivity on the preference of variable royalty scheme in the context of technology licensing. Drawing on the classic principalagent model, we assume that the variable royalty scheme is a process-based contract where the licensee is the principal and the licensor is the agent. The results show that informal governance facilitating goal alignment is positively associated with the variable royalty scheme (i.e. the process-based contract). Organizational receptivity promotes the legitimacy to imposing routines, evaluating the technology, and forming expectation, and is positively associated with the variable royalty scheme. Knowledge tacitness is negatively associated with the variable royalty payment, which implies less transfer programmability moves payment from variable royalties to a fixed fee. Our arguments are significantly different from classic principal-agent relationship that does not involve the dimension of licensee transfer and monitoring capacit
A Demographic Study of Buying Spontaneity on E-Shoppers: Preference Kolkata (West Bengal)
Get PDFOnline shopping or e-shopping has increased extremely in the past few years in India. Kolkata (West Bengal) is not so far behind. Lot of Online portals has been launched in india (like ebay, Amazon, Flipkart, Jabong, Myntra, Snapdeal etc.) and they have given a lot of opportunity and facility to buy products easily. It has improved the lifestyle of people in the country. Consumers tend to be attracted by the offers on the online shopping portals. This has resulted in increased impulsiveness among the buyers online. The study is an attempt to understand the effect of spontaneity among online buyers. For this research, online shoppers from Kolkata City were taken. The study indicated the fact that various factors contributed to the impulsiveness among buyers while they do online or e-shopping. Amongst them, unplanned tendency, online shopping mood and online shopping experience were identified as major factors. Demographic factors like age, gender, income and occupation of shoppers were also analyzed to know its effect on e-shopping spontaneous behaviour
Impact of Social Networks on Diffusion of Products
Get PDFIn light of the rapid growth of social networks around the world, this study analyses the impact of social networks on the diffusion of products and demonstrates the effective way to diffuse products in the society where social networks play an important role. We construct a consumer behaviour model by multi-agent simulation taking the movie market as an example. After validating it by using data from 13 US movies, we conduct simulations. Our simulation results show that the impact of social networks on the diffusion differs according to the customers’ expectations and evaluation for a movie. We also demonstrate the effective weekly advertising budget allocations corresponding to the types of movies. We find that the difference of weekly advertising budget allocations gives greater impact on the diffusion with the growth of social networks. This paper provides firm’s managers with important suggestions for diffusion strategy considering the impact of social networks
Institutional Sources of Resilience in Global ICT Leaders - Harness the Vigor of Emerging Power
Get PDFIn light of the significant impacts on global economy both nations and firms witnessed a dramatic advancement of information and communication technology (ICT). There was particularly bi-polarization between ICT advanced and growing economies compelling a vicious cycle between ICT advancement and its productivity decline in these economies. The institutional sources of resilience were analyzed. On the basis of an empirical analysis comparing technopreneurial performance in world top 500 ICT firms by market value, sales and profit over the last decade, resilient firms maintaining world top 100 position by all three values over the whole period were identified. Institutional sources enabling resilient firms maintain leading position can largely be attributed to co-evolutionary acclimatization ability, which harnesses the vigor of emerging power of counterparts both in home countries and in advanced countries as well as growing economies in a co-evolutional way. Such ability maximizes synergy between efficiency and resilience in their technopreneurial management. Contrasting business model in global ICT firms with and without resilience structure suggests the sources of emerging trap due to ICT advancement and endorsed the significance of co-evolutionary acclimatization. This suggests the significance of institutional co-evolution between ICT advanced and growing economies that enables both economies to harness the vigor of partners for global sustainability
Human Body Food Supply Chain and Inventory Models Analogy: An Empirical Validation
Get PDFThe purpose of this paper is to empirically validate or discard analogies between human body food supply chain and inventory flow in material management based on the paper titled ‘Inventory Models and Human Body Food Supply Chain: Some Managerial Insights’ by Vrat in which some conjectures were proposed by him. This paper is an attempt to take these conjectures forward to the level of postulates. This is an empirical study administered through two-phase surveys for determining shared perception of a wider group. This study also investigates the effect of age, gender and education on the perception of people on these conjectures. A-G-E (Age-Gender-Education) analysis is applied for this purpose. The findings indicate a strong parallel between Vrat’s conjectures and survey results. Findings of the A-G-E analysis indicate that the difference in the perception due to demographic factors is significant for many conjectures. It is hoped that this research will bring new insights for managers in handling various issues in a supply chain and also the scientific inventory models can help persons to gain better insights about food intake policies in human body
Appropriate Technology and Economic Development of Emerging Economies – A Myth or a Reality
Get PDFThe appropriateness of technology being purchased, transferred, and used by emerging economies has been an issue raised at different world forums and discussed with no appreciable change in the state of affairs. However there are changes occurring due to the innovative ways in which the same technology is put to use resulting in products that have found easy acceptance amongst the users. This development questions the premise on which appropriateness of technology is judged. The paper reviews the existing literature on appropriate technology and makes an attempt to identify the characteristics of an appropriate technology and validates these characteristics through the case study approach. The research points out two different facets of use of technology, one in which high technology and the products based on it are adopted without any modification and accepted too. The other is the use of high technology to develop products that are appropriate but are very different from the products for which the high technology was initially developed. Whether the technology is high or basic should not be a debatable issue, but technology that finds acceptance in the emerging economies becomes appropriate. Only those technologies have found acceptance, which take into consideration the economic, cultural, and environmental conditions prevailing in these emerging economies. The findings and the conclusions of the paper have implications for the policy makers as well as business enterprises of not only emerging economies but also of industrialized countries

An empirical analysis of China’s wind energy development trajectory over the last decade focusing on the technology sourcing from foreign firms in support of domestic players for accelerating functionality development through enhanced knowledge identification, absorption, assimilation and acclimatization was attempted. Important lessons learned include (i) importance of supply chain in the technology diffusion, (ii) effective technology acquisition and assimilation through early domestic firm engagement, (iii) effect of relevant domestic firms involvement in technology transfer partnership to induce inter-industry spillovers, and (iv) a framework for an emerging nation to develop new functionalities. Similarity and disparity with similar success of fusion in solar industry (JTMGE 3, 2) were also identified
Structural Source of the Trap of ICT Advancement - Lessons from World ICT Top Leaders
Get PDFIn light of the significant consequence of the trap of dramatic advancement of information and communication technology (ICT) in the global economy, both nations and firms that have been compelling their productivity decline. This resulted in great stagnation of ICT advanced economies and therefore its structural sources were analyzed. Based on an empirical analysis tracing, the trend in marginal productivity of ICT and its subsequent prices among the top ICT leaders in the world over the last two decades correlating with the effects of ICT, two faces of ICT advancement were identified. On one side, advancement of ICT contributes to its prices increase by new functionality development, its dramatic advancement particularly centered by internet results in the decline of its prices through freebies, easy copying, and standardization. It was demonstrated that the success of ICT leaders could largely be attributed to the way in which the two faces of ICT advancement were managed by maximizing the positive face of ICT advancement. This is done by means of the effective utilization of external resources in innovation while minimizing the negative face by outsourcing price decreasing factors. All of the aforementioned points can be invaluable lessons for global sustainability in both ICT advanced and growing economies in the midst of the advancement of ICT. The significance of innovation-consumption co-emergence for harnessing the vigor of counterparts is discussed
