| Abstract(in English) | All networked devices must be in secure state on the Internet. Even if a limited number of devices are not secure, the whole network can be damaged. Some Internet attacks such as the "Slammer" and "MSBlaster" worms are good examples. Current countermeasures against these are users being current with security news and applying all patches to their computers. However, these do not solve these problems. In this paper, we propose a scheme which proves security state of a device such as patch level of operating system, revision number of virus definition and so on, at any time. We then discuss construction of this scheme, which uses an unforgetable certificate. We then present two protocols that authenticate whether the states of devices are included in a qualifying group. It is difficult to forge the qualifying group under these protocols. Finally, we present two applications of our scheme which can ensure secure computing environment. Our scheme guarantees security against forgeries of state certificates and against malicious operations by security administrators. |
