摘要
主要分析了如何利用系统调用重定向技术,在基于Solaris的VFS(Virtual File System)构架下开发文件加密组件,并实现与操作系统的无缝工作.在简单文件加密模型的基础上作了进一步改进,提出了改进后的文件加密组件模型.结果表明,改进后的模型具有更高的效率,并且有效地降低了该模块对操作系统性能的冲击.
On the base of analyzing how to develop file enc/decryption system based on VFS of Solaris with the technology of redirection of system call and how to make it work with OS seamlessly, the author make progress on the simple model of file enc/decryption system and gives the improved model of fde enc/decryption system. The result shows that the improved model has better efficiency and reduces the impact to the OS on performance effectively.
