Current internet has evolved from the sharing and efficiency aspects of information, it is still vulnerable to the fact that the Internet is not secure in terms of security and is not safe to secure of security mechanism. Repeating patches on continuous hacking are continuously demanding additional resources for network or system equipment, and consequently the costs continue to increase. Businesses and individuals alike are speeding up the damage caused by crime like of ransomware, not jusy simple attacks, and businesses and individuals need to respond to cyber security. In addition, the ongoing introduce of security device, and separate of networks for secure transmission of contents in the existing TCP/IP system, but it is still lacking in security. To complement the security implications of this existing TCP/IP Internet Protocol, we intend to propose a Secure Contents Transport System (SCTS) on the network using the CCN concept.

The evolution of internet have opened the world of IPTV. With internet protocol, IPTV broadcasts contents stream. The IP protocol doesn't provide secure service due to IP characteristics. So, it is important to provide both connect and secure service. Conditional Access System and/or Digital Right Management are being used to protect IPTV contents. However, there exist restrictions in the view of security. In this paper, we analyse existing security technologies for IPTV and propose a novel method to enforce security efficiently. In the proposed method, OTP is used for encryption/decryption contents and CAS controls key for encryption/decryption and the right of user. With this scheme, it reduces the load of the system and provides more security.

Although various information and communication technologies occupy a place in daily life in the face of the fourth industrial revolution, the contents related to information security in elementary and secondary education courses are mainly related to personal information protection, and the contents and countermeasures of rapidly changing security threats are low in textbooks, and they are far behind the changes. To improve this, this paper suggests that education contents related to information security are included in elementary school real and middle school information textbooks, educational contents related to wireless network and PC security are included to cope with rapidly changing security threats that may arise from the age of the Internet of Things, non-face-to-face classes, and case-based information ethics education can be organized to eradicate curiosity about hacking. Through this paper, we will help prevent information security accidents by establishing basic security measures on our own and strengthening security awareness in the information age.

Information security is becoming a more important factor in distribution of digital contents. Generally, illegal facsimile of high-quality multimedia products such as DVDs, MP3s and AACs is possible without damaging quality. Thus, the illegal distribution of duplicated contents on the Web is causing digital content providers great economic loss. Therefore, a study of security and efficient distribution of digital contents is required. The most important issues in the design of a digital content distribution system are user convenience, execution speed and security. In this study, we designed a digital contents distribution system that uses web caching technology and encryption/decryption techniques in hierarchical structures. We propose a digital content distribution system that improves user convenience, security and execution speed. The superior performance of the proposed system has been proven in the tests. The results of experiment show that the developed system has improved the security of DC without decreasing process speed.

The network architecture and analysis model for evaluating the information security are presented to distribute the reliable and secure multimedia digital contents. Using the firewall and IDS, the function of the proposed model includes the security range, related data collection/analysis, level evaluation and strategy proposal. To develop efficient automatic analysis tool, the inter-distribution algorithm and network design based on the traffic analysis between web-server and user are needed. Furthermore, the efficient algorithm and design of DRM/PKI also should be presented before the development of the automatic information security model.

The purpose of this study is to suggest an operational plan for the information security department of colleges. First, the necessity for educating information security personnel was examined. Second, the institutes for educating information security personnel were investigated and the curriculum for information security of the college in Korea were examined. Finally, the challenges were examined and the solutions were suggested.

This paper shows how Ebooks contents can be securely transferred to consumers in wireless environment using public key infrastructure (PKI). In addition, we show the proposed scheme to be secure. The final goal is to show that our scheme satisfies all secure requirements of digital contents in any environments.

As information and communication technologies (ICTs) has been developed, it is getting more important for internet users to consider many security issues (e.g., privacy protection). In this paper we claims that animation contents make a positive influence on teaching such computer securities, and investigate what features of animation contents will be the most important relationships with performance of the teaching process. Once we have obtained the survey results from students, two main features (i.e., characters and plots) of the animation contents have positively influenced the performance of e-learning systems.

OMA(Open Mobile Alliance) is one of the most active group about DRM technology in mobile device field. OMA announced an OMA-DRM v 2.1 standardization in 2007. After then OMA announced OMA-SRM(Secure Removable Media) and SCE(Secure Contents Exchanges) that are the extension of OMA-DRM v2.1. In SCE, a user can form user domain to share contents and rights. So the user can share contents and rights with not only the the OMA-DRM v2.1 but also home devices like mobile phones, personal computers and audios. In this paper, we analyze a sharing technology of OMA-DRM and SCE, and then propose key distribution method using proxy re-encryption and smart card to use shared contents and rights.

As Internet use is widespread advertising through the Web, shopping, banking, etc. As the various services offered by the network, the need for Web security is increasing. A security system for the protection of information assets and systems against various types of external hacking threats and unlawful intrusion will require. Intrusion Detection Tool of the paper web will have is to increase the security level, to prevent the loss of resources and labor spent by the individual monitoring of the web. Security intrusion detection system analyzes the cause of the problem of the security vulnerability and exposure of the information on the Web. Using a monitor to determine a fast support of security is to design a security system for the purpose of protecting the information security vulnerability and exposure information.
