Outline of Final Research Achievements

Our information society is developing so rapidly that it is a pressing issue to keep the reliability and safety of IT systems at a much higher level than before. In this research, we have developed innovative technologies to minimize the damage and keep the correct operation or to restore functions with minimal overhead even if there is a breakdown or intrusion in the IT system. Specifically, we proposed and verified new element technologies such as delay concealment by time borrow, fine-grained partial reconstruction on demand, stream-oriented protection against attacks, real-time abnormality prediction, and integrated them to realize a resilience-oriented computer which efficiently operates all the functions. In addition, we have developed a testbed to prove its effectiveness.
