PKI(Public Key Infrastructure)-based information certification technology has some limitations to be universally applied to mobile banking services, using smart phones, since PKI is dependent on the specific kind of web browser, Internet Explorer. OTP(One Time Password) is considered to be a substitute or complementary service of PKI, but it still shows low acceptance rate. Therefore, in this research, we analyze why OTP has not been very popular, and provide useful implications of making OTP more extensively and frequently used in the mobile environment. Perceived security of OTP was set as a higher-order construct of integrity, confidentiality, authentication, and non-repudiation. Research findings show that security awareness and perceived security of OTP is positively associated, and the relationship between perceived security and trust on OTP is statistically significant. Also, trust is positively related to intention to use OTP continuously.

The purpose of this paper is to study the send and receive of the message in the TEDI System. The TEDI System replaces a series of trade documents with electronic date, and it realizes secure and reliable transactions of data among parties by means of open networks, such as the Internet. The TEDI system is composed of Web browsers, TC Serves, a RSP Server, and Certification Servers. TEDI has development the system and legal frame work. Exporters, importers, carriers, banks insurance and companies those who engage in the trade releated business have tested TEDI system and evaluated the legal frame work from the practical point of view. TEDI is now refining the system and preparing for the service. A fundamental feature of the TEDI System is the attribution to participants of data messages through public key certificates issued by certification authorities that allow for verification of digital signatures. Access to servers maintained by such certification authorities also takes place through the internet. In principle, certificates used by any reputable certification authority may be employed as long as they are compatible with X.509 V3.

Residential broadband networks (RBN) are quickly evolving from xDSL/Cable networks to FTTH services with lOOMbps bandwidth. With the high-speed Internet services, subscribers tend to use web, multimedia, game or file sharing applications. Therefore, performance of RBN is important to the quality of services for users. Typically, Internet service providers (ISPs) are providing their RBN performance results that are measured by subscribers with the dedicated measurement tools. However, they do not make their results public to people. In order to obtain the performance results measured by users, we have to induce a lot of subscribers, which will take a lot of cost and time. Monarch, that is used in this paper, could provide the 3rd party measurement method without the help of ISPs and subscribers. With the extensive experiments through Monarch, we have shown that 3rd party measurement results are not much different from those of user-initiated measurement. In addition, we have observed that bandwidth is around $80{\sim}90Mbps$ and RTT is less than 30ms in FTTH services provided by three major Korean ISPs.

Spring framework is widely used as a base technology for e-government frameworks and to the extent it is a standard for web service development tools of Korean public institutions. However, recently, a remote code execution vulnerability(CVE-2018-1270) was found in an application using a spring framework. This paper proposes a method of analyzing the vulnerability experiment using a hacking scenario, Proof Of Concept(POC), in which the spring framework is a hazard to the server. We propose the patch to version 4.3.16 and version 5.0.5 or later as an ultimate response. It is also expected that the proposed experiment analysis on vulnerability of hacking scenario will be used as a data for improving performance of security programs and establishing a new authentication system.

Assistive technologies are necessary for ensuring independent living and equal participation in an information-based society for people living with disabilities (PLWD). This study investigated the assistive technology preference of students with visual disabilities, and the approach academic libraries should adopt in procuring assistive technologies. The study adopted a quantitative research method, with a survey as the research design. The study was conducted among visually disabled students in four public universities in Nigeria. Using the total enumeration method, an online questionnaire was used to obtain information from 151 students who voluntarily agreed to partake in the survey. The study found that access to electronic resources, scanning/conversion of print resources to electronic formats and access to information on the Web were among the technology-based services provided to visually disabled students. COBRA, ZoomText, Supernova and Dragon Naturally Speaking are the most preferred assistive technologies (software). At the same time, handheld scanners ($\bar{x}=4.40$) and braille keyboards ($\bar{x}=4.60$) are the most preferred assistive technologies in the hardware category by visually challenged students. The study further revealed that the library management should consult with students living with a visual disability before procuring assistive technology. Findings from this study thus provide further evidence of the need for librarians to fulfil their moral and legal obligation in advocating the provision of assistive technologies. Library administrators and university stakeholders should expedite actions on meeting the assistive technology needs of people living with visual disabilities. These actions should transcend mere policy formulation on the provision of assistive technologies to restructuring their services and spaces to accommodate assistive technologies as information service delivery tools for people with visual disabilities.
