K-pop has become a truly global phenomenon thanks to its distinctive blend of addictive melodies, slick choreography and production values, and fans all over the world buy anything to support their favorite K-pop idols. In this paper, we will design and create an online K-pop Shopping mall made not only for korean fans but also international fans. Furthermore, the site will include Official Merchandise and Unofficial merchandise thus opening a job opportunity for those who have interests in K-pop business.

In digital contents distribution environments, a user authentication is an important security primitive to allow only authenticated user to use right services by checking the validity of membership. For example, in Internet Protocol Television (IPTV) environments, it is required to provide an access control according to the policy of content provider. Remote user authentication and key agreement scheme is used to validate the contents accessibility of a user. We propose a novel user authentication scheme using smart cards providing a secure access to multimedia contents service. Each user is authenticated using a subset of attributes which are issued in the registration phase without revealing individual's identity. Our scheme provides the anonymous authentication and the various permissions according to the combination of attributes which are assigned to each user. In spite of more functionality, the result of performance analysis shows that the computation and communication cost is very low. Using this scheme, the security of contents distribution environments in the client-server model can be significantly improved.

This paper tries to solve the problems which previous methods have the model using smart card for protecting digital contents. This study provides a contents distribution model to protect the rights of author, distributor, and user as well as user's information by using technologies such as cryptography, DRM(Digital Right Management), access control, etc. The proposed system is evaluated as the most safety model compared with previous methods because it not only solves the problems which the previous methods have, but also protects four type of risks such as use of contents which other mobile devices download, the attack on the key to decode the message, the attack on leaking the contents, and the internal attack such as an illegal reproduction.

Recently, the weight of high-quality multimedia contents is explosively growing out of the network total traffic. This steep increase of media contents to require huge traffic does not contribute to the generation of revenue streams and it leads to the situation of dumb pipe to trouble network providers into the big burden of investment on the network expansion. Accordingly, the transfer to the smart network to enable the effective delivery of large-scale media is imminently challenging issue to the network providers to seek the profitable business. The smart network revolves around the technologies to enhance end-to-end quality and fair usage with network resources and to optimize the traffic for the contents delivery over the concept of Content-Centric Network. In this paper, we propose an architecture and fundamental functions suitable for the smart network and suggest improved test results through the construction of an experimental network.

Recently, digital rights management (DRM) related researches are widely spreading with prosperity of IT industries. The DRM technology protects proprietor of copyright by preventing mischanneling and illegal copy. In this paper, we propose a new DRM model that has an enhanced and efficient protocol based on certificate using smart card. The proposed model overcomes weaknesses of WCDRM model and has following additional advantages: first, copy protection is enhanced by hiding user's specific information from attacker by storing the information within smart card; second, server load for contents encryption is reduced by making clear protocols among author, distributer, certificate authority, and users; third, offline user authentication is guaranteed by combining partial secret values in media players and smart card. Exposure of core information also is minimized by storing them in smart card. In addition, we show that the proposed system is more secure than WCDRM model by comparing various factors of anonymous attackers.
