Research summary
Challenges from System Software There are some works to be done only by the operating system. I aim to achieve innovation from the core of computer software. 【Subject of research (1) Summary】 Processors started to have the capability of supporting virtual machine management. This capability has enabled one PC to run more than one OS. Under this circumstance, I study the system that achieves adaptive load balancing or resources allocation among the OSs. 【Subject of research (2) Summary】 A virtual machine can run more than one OS on one PC. There are, however, some issues on running realtime OS. In particular, assuming the built-in system, I study how to configure a virtual machine monitor that can have a real time OS as a guest OS. 【Subject of research (3) Summary】 I seek a technique to solve information leakage problems as social problems from the viewpoint of operating system. To be more specific、I study the method to control access due to importance of each data and the circumstance where data is manipulated. 【Subject of research (4) Summary】 As network users increase, malicious software also increases, such as virus and Trojan horse. In addition, the methods are further sophisticated. Against this, I study technologies to analyze malware effectively and securely by using virtualization technology. 【Subject of research (5) Summary】 Although wireless communication technologies, notably wireless LAN, have become widely used, some issues remain unsolved, including running out of radio frequencies, realizing fast communication and guaranteeing communication quality. I conduct a study of solving these issues by fusing software wireless technology of the operating system.
