Abstract: To resolve the problem of low efficiency when applying current security tools to the file integrity checking of e-government websites, this paper proposes a file integrity checking system based on CityHash under UNIX and describes the system’s overall architecture and implementation. The characteristics and advantages of CityHash are summarized and analyzed. The system uses CityHash to generate each file’s hash code. Performance analysis proves its feasibility and advantage. Applying the system to e-government websites helps the administrator to find out the tampered files rapidly and reduce the risk.
