基于分区表的移动存储介质标识方法

Method of Marking Removable Storage Medium Based on Partition Table

移动存储介质在涉及安全的应用场合需要对其进行标识。给出基于磁盘分区表实现移动存储介质标识的方法,对分区表的结构和工作原理、在分区表空闲表项中写入和访问标识的方法等进行阐述,并给出核心代码。结果表明,该方法不但可行,而且具有其他方法所没有的优点,是对移动存储介质进行标识和认证的一种新的手段。

It is necessary for removable storage medium to be marked when involving the application of security. The new method for marking removable storage medium based on partition table is put forth. The formation and principle of partition table are discussed, the method to modify and cheek the vacancy partition table item is described, and some key codes are presented. The result indicates that it is a new technical method for removable storage medium to be marked and authenticated.
