This study is applied to the Erikson's concept of generative fathering that meets the needs of the next generation and investigated the relationship between generative fathering and the attachment security. Sixty-five of 30-36 months old children (37 boys and 28 girls) and their parents participated in this study. Fathers completed the questionnaire of parental generativity, which include items on their support of physical development, social-emotional development and intellectual development. Children's attachment was reported by mothers using the Attachment Q-set. Results revealed that father's parental generativity was noted as 3.09 in 1 to 5 child rearing activities. But the results showed that there was a significant difference in child's sex and child's birth order. Also, it was found that children's secure attachnent to their fathers was not high. There was an association between fathering generativity and children's secure attachment. This findings imply that father's active child rearing participation will increase children's secure attachment.

Agile methodologies have gained recognition as efficient development processes through their quick delivery of software, even under time constraints. However, like other agile methods such as Scrum, Extreme Programming (XP) and The Dynamic Systems Development Method (DSDM), Feature Driven Development (FDD) has been criticized due to the unavailability of security elements in its twelve practices. In order to examine this matter more closely, we conducted a systematic literature review (SLR) and studied literature for the years 2001-2012. Our findings highlight that, in its current form, the FDD model partially supports the development of secure software. However, there is little research on this topic, as detailed information about the usage of secure software is rarely published. Thus, we have been able to conclude that the existing five phases of FDD have not been enough to develop secure software until recently. For this reason, security-based phase and practices in FDD need to be proposed.

With various sensors and communications capabilities, the Internet is growing larger as the internet can communicate with the Internet. Given the growing vulnerability of the internet market, the development of security and security is increasing, and the development of the internet is actively evolving and the development of the internet is actively being carried out. In particular, it is required to introduce lightweight and secure authentication schemes, especially those that are difficult to use due to the difficulty of using authentication schemes. Thus, the safety of the secure authentication system of the Internet is becoming very important. Therefore, in this thesis, we propose certification technologies on secure objects to ensure correct, safe communication in the context of the internet context.

Recently, with the development of the ICT environment, the use of the software is growing rapidly. And the number of the web server software used with a variety of users is also growing. However, There are also various damage cases increased due to a software security vulnerability as software usage is increasing. Especially web shell hacking which abuses software vulnerabilities accounts for a very high percentage. These web server environment damage can induce primary damage such like homepage modification for malware spreading and secondary damage such like privacy. Source code weaknesses checking system is needed during software development stage and operation stage in real-time to prevent software vulnerabilities. Also the system which can detect and determine web shell from checked code in real time is needed. Therefore, in this paper, we propose the system improving security for web server by detecting web shell attacks which are invisible to existing detection method such as Firewall, IDS/IPS, Web Firewall, Anti-Virus, etc. while satisfying existing secure coding guidelines from development stage to operation stage.

In this study, we suggest the selecting evaluation method considering 6 major factors like Compliance system application (Development language conformance, Platform Compliance), threat evaluation (criticality of security incident, possibility of security incident), application benefit (Reliability / quality improvement, Modify Cost) for appropriate secure coding rule selecting evaluation. Using this method, we selected and make a set consist of 197 secure coding rules for Battlefield Management System Software. And calculated the application priority for each rules.

According to IT technology has evolved, smart phone rapidly propagates for mobility. A smart phone user acquires useful information, but attackers generate various damage. For example, an attacker must distribute to expose the privacy of others. To solve this problem, various information security products are being developed. In addition, information security has been strengthened. In this paper, we propose a scheme for secure use of smart phone. For development of secure smart phone, the development processes should be secure. In addition, we propose an information security production certification system for secure smart phone security.

This paper presents a secure Linux OS in which multi-level security functions are implemented at the kernel level. Current security efforts such as firewall or intrusion detection system provided in application-space without security features of the secure OS suffer from many vulnerabilities. However the development of the secure OS in Korea lies in just an initial state, and NSA has implemented a prototype of the secure Linux but published just some parts of the technologies. Thus our commercialized secure Linux OS with multi-level security kernel functions meets the minimum requirements for TCSEC B1 level as well kernel-mode encryption, real-time audit trail with DB, and restricted use of root privileges.

다양한 응용분야에서 사용되고 있는 웹은 최근 전자상거래 둥에서의 이용에 대한 기대가 한층 고조되고 있다. 그러나 이러한 웹은 전자상거래 행위에서 특히 중요한 부인봉쇄 서비스가 제공되고 있지 않으며 64비트 이하의 비도로 기밀성 서비스를 제공하고 있다. 이 논문에서는 WWW의 보안 요구사항 및 이를 위한 WWW 프로토콜로 IETF(Internet Engieering Task force)에서 제안한 S-HTTP(Secure HTTP, Secure HyperText Transfer Protocol)를 기반으로 하는 안전한 WWW시스템 개발, Apache-Shttp를 위한 기능 설계, 개발 환경 및 개발된 시스템의 시연을 기술한다.

Secure digital payment is critical in the successful shaping of global digital business. Digital payments are increasingly being used as a substitute to traditional payments, contributing markedly to the efficiency of the economy. The focus of every digital business transaction is to minimize risks arising from transactions. It is essential to ensure the security of digital payment whether used in internal networks or over wireless Internet. This paper analyses secure digital payment methods from the viewpoint of systemic security and transaction security. According to comparative analysis of digital payment models, this paper proposes a comparative analysis framework to investigate and evaluate secure digital payment. In conclusion, the comparative analysis framework, comparison of digital payment models and mobile payment models proposes a useful academic and practical foundation to enhance the understanding of secure digital payment methods. It also provides academic background and practical guidelines for the development of secure digital payment systems.

Development of ICT technologies leads exponential growth of various sharing economy over the last couple of years. The intuitive advantage of the sharing economy is efficient utilization of idle goods and services, but there are safety and security concerns. In this paper, we propose a onetime password based access control system to support secure accommodation sharing service and show the implementation results. To provide a secure service to both the provider and the user, the proposed system issues a onetime access password that is valid only during the sharing period reserved by the user, thereafter access returns to the accommodation owner. Especially, our system provides secure user access by merging the two elements of speaker recognition using voice and a one-time password to open and close the door lock. In this paper, we propose a secure system for accommodation sharing services as a use-case, but the proposed system can be applicable to various sharing services utilizing security-sensitive facilities.
