Research Themes

Organization methodology of information systems which are the key elements of information society where we can live and work with relief depending on many information systems: secure system organization, high reliable system organization, and dependable system organization of long term. That is, research of system architecture which is the design technology of computer systems by combining many elemental technologies: basic software such as secure operating systems and secure programming, secure Web service organization, intrusion detection, secure network system, and malware analysis.
