چکیده انگلیسی
In this paper, we study the logic structure and operation characteristics of flash memory, and survey related work on secure data deletion. In addition, we define the adversary capability and threat model, putting forward the design goals that secure data deletion scheme needs to meet. Then an approach in user space that uses the user space file system to provide secure deletion guarantees at file granularity is proposed, independent of the characteristics of the underlying file system and storage medium. The approach encrypting every file on an insecure medium with a unique key that can later be discarded to cryptographically render the data irrecoverable. Moreover, we implement our secure data deletion approach on Android platform named SADUS. Finally, experiments are conducted, and the results indicate that SADUS prototype ensures the secure deletion of data in flash memory on mobile devices with comparable overhead and it can meet the requirements of the users in daily use.
