| 摘 要： | 为解决文件系统过滤驱动加密系统中的认证问题,增强保护的粒度控制,提高文件加密系统的安全性,在原有文件系统过滤驱动的加密系统基础上,提出了包含认证,eKey模块、分级保护与密钥管理等机制的增强型文件加密系统设计方案,建立了实体与身份两级认证机制,实现了多级文件密钥和密钥访问控制.采用Windows NT内核驱动框架,基于文件系统过滤驱动技术,结合eKey功能模块加以实现.测试结果表明,该设计方案有效且可行,为文件保护提供了一种更加安全可靠的解决思路.

| Abstract: | To solve authentication in encryption systems based on file system filter driver, enhance protection control in detail and improve the system security, a enhanced file encryption system design proposal including authentication, eKey module, multi-level protection and key management is proposed based on existing file system filter driver encryption system. Two level authentication included entries and identities are designed. Multi-level file key and key access control are achieved. Solution is implemented b... |
