Development of Security Device　　＊　unpredictable true physical random numbers　＊

In science, technology, economy-related condition and risk management, it is dangerous in simulated calculation to use pseudorandom numbers. Practical use of true physical random numbers with high-speed and low price is expected. Meanwhile, high level security is required urgently for commercial transaction using IC card and electronic device, exchange and management of information. It is possible to ensure information security by using pseudorandom numbers. However, pseudorandom numbers is readable to use calculator because pseudorandom numbers is created from pseudorandom numbers calculator.
As the fact that more than 70% of computer crimes are committed by internal people,working within the organization. It is important to enhance the security, which even concerned people who totally knows systems can not crack. Not only password and personal verification but also cipher key using unpredictable true physical random numbers are required. The demand of applications which is using cipher key, generated from physical random numbers are increasing and it is expected in various fields; IC card, Credit card, electronic money, mobile phone, consumer–electronics equipments(TV and PC), key systems, electric games, important files, large bills, LAN board, router and so on. By strengthening cooperation and collaboration with the academics and professor in a national university, who developed this cipher key, we are aiming for product differentiation and creating good brand images.
