| Abstract: | With the development of information technology， the exchange of information between people is becoming more and more frequent，mobile stroage devices are widely used for their larage capacity and easy to carry. In order to improve the security performance of mobile storage devices， virtual disk technology is proposed and implemented in a data secure management software with Chinese cryptographic algorithm. A virtual driver between the physical disk driver and the file system are used to implement a security partition by written as an image file from the mobile storage device and create a hidden area on the mobile storage device， and the configuration information of the security zone is stored in the hidden aera. SM4 chinese cryptographic algorithm is implemented to protect the data of security partition. Multi-threading technology is used to improve SM4 encryption and decryption speed in this paper. |
