摘要
针对现有安全性检查工具应用于政务网站文件完整性检查效率低的问题,提出了UNIX环境下的基于CityHash的文件完整性检查系统并对其架构和模块进行了描述。分析总结了现代哈希City Hash的特点和优势,将其应用到系统中文件哈希值的生成。通过性能测试证明该方法是具有可行性和高效性的,将此系统运用到政府电子政务网站的文件完整性检查中能够迅速发现被篡改的文件,将危害降低到最小。
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 City Hash under UNIX and describes the system＇s overall architecture and implementation. The characteristics and advantages of City Hash are summarized and analyzed. The system uses City Hash 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.
