While the internet has evolved in terms of information sharing and efficiency, it is still prone to security attacks and remains vulnerable even when equipped with a security mechanism. Repeated patching against hacks involves excessive wear of system equipment and high costs. Methods of improving network security include the introduction of security equipment and network partitions, but they have not been fully effective. A fundamental solution is the Operation Content Network (OCN), which enables the strengthening of authentication. In this paper, Instead of following the existing TCP/IP system, OCN establishes an immunity-based security system through content-centric communications. Data transmission occurs over a Content Centric Network (CCN), which is provided with a protocol verified by the CCNx group. Areas protected by OCN rely only on CCN for communication without using any IP. As such, it defends the system against unknown attacks, including zero-day attacks.

With a huge demand for replicated content on the Internet, a new networking paradigm called information-centric networking (ICN) has been introduced for efficient content dissemination. In ICN, named content is distributed over the network cache and it is accessed by name instead of a location identifier. These aspects allow users to retrieve content from any of the nodes having replicas, and consequently 1) network resources are more efficiently utilized by avoiding redundant transmission and 2) more scalable services are provided by distributing server loads. However, in-network caching in ICN brings about a new type of security issues, called content poisoning attacks, where fabricated content is located in the network cache and interferes with the normal behavior of the system. In this paper, we look into the problems of content poisoning in ICN and discuss security architectures against them. In particular, we reconsider the state-of-the-art schemes from the perspective of feasibility, and propose a practical security architecture.

With the emergence of increasingly complex networks and diverse user terminals, demand for the next generation IPTV service is rapidly growing. It enables any content to seamlessly be reused on the diverse terminals as well as be broadcasted in real-time through the complex networks. In this paper, a novel security framework is proposed for the real-time and reusable IPTV services. The proposed framework is advantageous over the conventional content protection techniques in easily producing the scalable content with lightweight, perceptual, transcodable, and adjustable security features. It does not only ensure end-to-end security over the entire service range based on a single security mechanism, but also can control a level of security while dynamically transcoding the original content. This approach basically performs selective encryption during and after the compression using scalable video coding. The suitability of the proposed approach is demonstrated through experiments with a practical service scenario. Therefore, it is expected that security technology alone could practically contribute to creating new business opportunities for IPTV services.

Today people adopt various contents from their mobile devices which lead to numerous platforms. As technology of 5G, IOT, and smart phone develops, the number of people who create, edit, collect, and share their own videos, photos, and articles continues to increase. As more contents are shared online, the numbers of data being stolen continue to increase too. To prevent these cases, an authentication method is needed to encrypt the content and prove it as its own content. In the report, we propose a few methods to secure various misused content with secondary security. A unique private key is designed when people create new contents through sending photos or videos to platforms. The primary security is to encrypt the "Private Key" with a public key algorithm, making its data-specific "Timeset" that doesn't allow third-party users to enter. For the secondary security, we propose to use Message Authentication Codes(MACs) to certify that we have produced the content.

The purpose of this study is that there viewing at the future development direction and awareness of the cultural contents industry targeting college students for the activation of the domestic cultural content industry. And we want to find the need of the security industry & Concert Hall Safety. Recent worldwide it has occurred 'Soft target' terror targeting unspecified civilian in the cultural space of theater and music venues, stadiums etc. But security and safety systems against terror in Korea are very deficient situation. US security market has increased sales significantly interest in increasing against crime and terrorism prevention and depending on the price cut and technology development. It is expected to require a security industry in a variety of applications to the cultural contents industry development about Korean pop music and theatrical performances, and internet and mobile games stc.

In this paper, we propose a redistribution mechanism of the content that is adapted to devices, which may have different display size and computing capabilities, in home network. The proposed system introduces a mechanism that the encrypted content compressed by H.264/SVC(Scalable Video Coding) scheme which has been standardized recently is provided to the device into a level of content suitable to each device capability. To efficiently superdistribute SVC content, this paper defines three requirements and proposes redistribution mechanism which satisfies these requirements using another licence that it is called 'Ticket'. Our system allows devices to redistribute the content freely in the domain using domain key.

There are two elements of security policy that can have a bearing on its effectiveness: content and form. While the content of the security policy has been investigated extensively in the most of the previous studies, there is very little literature on the form of the security policy. Since the form of the policy influences its success, it is important to understand how to articulate the form of a security policy. Thus, the aim of this study is to investigate the relationship between security form and policy compliance of employees. Research results find that dimensions of security form have effect on attitude towards security compliance, subjective norm, perceived behavioral control, and perceived response costs, and besides attitude towards security compliance and subjective norm have an effect on persistent security compliance intention. The conclusions and implications are discussed.

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.
