Summary:Recently, solid-state drives (SSDs) have been widely used in modern storage systems because of their excellent access performance and high energy efficiency. Therefore, secure deletion is critical for users to protect their data privacy against unauthorized access. However, the inherent access characteristics of SSDs bring in a grand challenge to thoroughly remove the sensitive data from the storage devices or make them inaccessible permanently. Moreover, the existing erase mechanism of SSDs may indirectly reduce the SSD lifetime when performing a secure deletion because of the massive block erases. To address these issues, we propose FSD, a file-related secure deletion that exploits the file information hints via multi-streamed SSDs to optimize the data allocation to alleviate the impact of secure deletion for prolonging SSD lifetime. The extensive experiments show that FSD satisfies the requirement of secure deletion and significantly prolongs the SSD lifetime by mitigating about 80% of block erases as well as extra data movement.
