Most previous electronic commerce studies have focused on a single product or similar products. The effects of different product types have been relatively neglected. and so previous studies have limited the generalization. The purpose of this study was to explore the effects of different product types. The Internet product and service classification grid proposed by Peterson et al.(1997). A survey-based approach was employed to investigate the research questions. Regression analysis demonstrated that the determinants of online shopping acceptance differ among product or service types. As a result of analysis, personal innovativeness of information technology, perceived Web security, personal privacy concerns, and product involvement can influence consumer acceptance of online shopping, but their influence varies according to product or service types.

The information security industry is increasing in importance and market size due to the development of the fourth industry such as artificial intelligence, IoT and etc. This paper was analyzed the impact of the increasing information security industry on the domestic economy by using the Input-Output table. It was classified industrial sectors into information security products and information security services industries, and then reclassified the Input-Output table into 35 industries. And it was estimated the production inducement coefficient, the value-added inducement coefficient, employment inducement coefficient, and etc. The production inducement coefficients of the information security product and service industry are each 1.571, 1.802, and the value-added inducement coefficients of them are each 0.632, 0.997, and the employment inducement coefficients of them are each 2.494, 7.361. Only the value-added inducement coefficient of the information security service industry is slightly higher than the total industry, and the remaining inducement coefficients are all lower than the total industry. In addition, the information security product industry has no the forward and backward linkage effect, and the information security service industry has no the backward linkage effect. But it has the forward linkage effect. As a result of analyzing the economic ripple effect of the information security industry, the production inducement amounted to 359.9 trillion won, value-added inducement amounted to 164.8 trillion won, and employment inducement amounted to 803 thousand people.

Inner product encryption (IPE) scheme is a cryptographic primitive that provides fine grained relations between secret keys and ciphertexts. This paper proposes a new IPE scheme which achieves fully attribute hiding security. Our IPE scheme is based on bilinear groups of a composite order. We prove the fully attribute hiding security of our IPE by using dual encryption system framework. In performance analysis, we compare the computation cost and memory requirement of our proposed IPE to other existing IPE schemes.

With the recent increase in damage caused by malcious codes using software vulnerabilities in Korea, it is essential to install anti-virus to prevent malicious codes, However, it is not easy for general users to know which anti-virus product has good performance or whether it is suitable for their environment. There are many institutions that provide information on anti-virus performance outside of korea, and these institutions have established their own test environments and test evaluation items, but they do not disclose detailed test environment information, detailed test evaluation items, and results. In addition, existing quality evaluation studies are not suitable for the evaluating the latest anti-virus products because there are many evaluation criteria that do not meet anti-virus product evaluation. Therefore, this paper establishes detailed anti-virus evaluation metrics suitable for the latest anti-virus evaluation and applies them to 9 domestic and foreign anti-virus products to verify the functions and performance of anti-viruses.

Many organizations are threatened by numerous information security attacks which are resulting in information security incidents. To prevent information security incidents, organizations invest on various information security measures like information security products, monitoring services and security training and educations. However they do not have enough knowledge about measurable utilities of information security investments. Since there is little studies empirically examining the effect of information security investments, this research aims to find out utilities of information security investment. We especially focuse on information security service investments. This study examined the data from the survey on information security for business sector which was conducted by Korean information & security agency. We utilized negative binomial regression model, which is a suitable model for over-dispersed count data. We found out that an investment on information security education and vulnerability testing have direct impact on reducing information security incidents. This research academically contributed to shed light on the utility of information security investments on reducing information security incidents. This research practically contributed to providing information security investment guideline for organizations which want to reduce information security incidents efficiently.

According to the NIS, damages due to leaking industrial technology are reaching tens of trillion won. The type of damages are classified according to insider leaks, joint research, and hacking, illegal technology leaks and collaborated camouflaged. But 80% of them turned out to be an insider leak about connecting with physical security. The convergence of IT and non IT is accelerating, and the boundaries between all area are crumbling. Information Security Industry has grown continuously focusing Private Information Security which is gradually expanding to Knowledge Information Security Industry, but Information Security Industry hereafter is concentrated with convergence of IT Security Technology and product, convergence of IT Security and Physical Security, and IT convergence Industry Security. In this paper, for preventing company information leaks, logical security and physical security both of them are managed at the same level. In particular, using convergence of physical security systems (access control systems, video security systems, and others) and IT integrated security control system, convergence security monitoring model is proposed that is the prevention of external attacks and insider leaks, blocked and how to maximize the synergy effect of the analysis.
