  • Recently, security researches have been processed on the method to cover a broader range of hacking attacks at the low level in the perspective of hardware. This system security applies not only to individuals' computer systems but also to cloud environments. "Cloud" concerns operations on the web. Therefore it is exposed to a lot of risks and the security of its spaces where data is stored is vulnerable. Accordingly, in order to reduce threat factors to security, the TCG proposed a highly reliable platform based on a semiconductor-chip, the TPM. However, there have been no technologies up to date that enables a real-time visual monitoring of the security status of a PC that is operated based on the TPM. And the TPB has provided the function in a visual method to monitor system status and resources only for the system behavior of a single host. Therefore, this paper will propose a m-TMS (Mobile Trusted Monitoring System) that monitors the trusted state of a computing environment in which a TPM chip-based TPB is mounted and the current status of its system resources in a mobile device environment resulting from the development of network service technology. The m-TMS is provided to users so that system resources of CPU, RAM, and process, which are the monitoring objects in a computer system, may be monitored. Moreover, converting and detouring single entities like a PC or target addresses, which are attack pattern methods that pose a threat to the computer system security, are combined. The branch instruction trace function is monitored using a BiT Profiling tool through which processes attacked or those suspected of being attacked may be traced, thereby enabling users to actively respond.

  • IT 사회의 변천에 따라 더욱더 중요시 되는 것이 컴퓨터 시스템 보안이다. 이 보안에 대한 위협 요소를 줄이기 위해서 TCG(Trusted Computing Group)은 TPM(Trusted Platform Module)이라는 반도체 칩을 기반으로 한 신뢰성 플랫폼을 제안하였다. 본 논문은 네트워크 서비스의 기술발전에 따른 모바일 환경에서의 TPM 칩을 기반으로 동작하는 컴퓨팅 환경의 신뢰 상태 및 시스템 자원에 대한 상태 정보를 실시간 모니터링한다. 또한 모니터링 중인 컴퓨터 시스템의 프로세스에 대해 BiT Profiling 기법을 통한 분기 명령 추적을 모니터링하며, 이를 통해 사용자가 능동적인 대처가 가능하도록 한다.
