| Abstract | The Grid is a technology that can dynamically integrates various elements, such as processor resources including PC and WS and data storage, on a network to build a unified system that can be shared among many users. Now the Grid technology equipped with new functionalities to realize a form of advanced collaboration and to achieve dramatic cost reduction has been used not only for a scientific field but also for business. Under such situation, required is that users can access to the Grid in a safe and robust way. In this research, a secure Grid environment is proposed and constructed through the application of a suite of security solutions to the Grid environment. The solutions have adopted IP security (IPsec) and Internet Key Exchange (IKE) as base technology. Furthermore, in this paper, our secure Grid environment is realized on IPv6 network, so that our Grid environment addresses the shortage of IPv4 addresses. Throughout the paper, we describe the techiniques to build a secure Grid environment on an IPv6 network and its mechanism in detail. |

| Abstract | Scientific data acquired from advanced measurement devices have increased in amount due to the recent development of measurement technologies.To efficiently analyze such data within a realistic time, the Grid is seen as an important computing platform for advancement of science.This paper discusses a Grid-enabled analysis system for brain function.The system enables medical doctors and scientists to analyze a large amount of data acquired from magnetoencephalography, a highly-sophisticated medical device with high efficiency. The feature of this system is in a job-sequence control mechanism based on user's region of interest for data. In this paper, we describe the design and implementation of the system and then evaluate the system qualitatively. | |||
