Security Technologies to Improve Content-Distribution and Broadcasting Services

Abstract

Nowadays, technologies for information security have become essential in the cyberspace world. A lot of PC users know their values, but they do not have a good impression on the technologies. As the CPU of PCs is more powerful, the load caused by security technologies becomes comparably small. However, as you know, another powerful cyber-attack appears. This means, another security technology has to be installed in the PC, and the users do not feel that the CPU load caused by security technologies is relieved. To remove this feeling of disgust even if only slightly, what kind of technology should be developed? In this paper, the developments against such issues are explained.
