内核移植及其保护方法

内核移植工作是一项具有实际应用价值和各项配置较为复杂的工作,故提出一种依据内核本身特性实现内核更新的方法.现有大部分内核移植的方法需要利用module-init-atools、mkinitrd、lvm2和device-mapper等工具进行,而该文提出的移植方法摒弃了外部工具,依据内核自身特点实现新内核更新及其策略保护.首先,进行内核的配置,对必要模块进行分析配置;然后利用内核特性进行的模块化编译和grub界面分析;再次,鉴于对内核的健壮性要求,采用改进后MD5算法机制实现对内核的保护.最后实验研究表明,该内核移植方法便捷实用,优化的保护机制对内核具有重要的应用价值.

Method of Kernel Transplantation and its Protection

The work of kernel transplantation has practical application value and the configuration more complex tasks. So this paper comes up with a new method of kernel updates on the basis of the kernel itself characteristics. Most of the existing kernel transplantation methods need to complete with the module init-tools, mkinitrd, lvm2 and device mapper and other tools, external tools are abandoned in this paper. It is to achieve the new kernel updates and its strategy is on the basis of the kernel protection characteristics. First of all, for kernel configuration, we analyze the necessary module configuration. Then it uses the command interface to the kernel of modularization compile and grub analysis. Again, in view of the robustness requirements for the kernel, the kernel is realized with the MD5 algorithm which can improve the mechanism of protection. Finally experimental research show that the kernel transplantation method is convenient and practical, and the improved protection mechanism of the kernel has important application value.
