Abstract:
The ability to delete sensitive data securely from electronic storage is growing in importance. However, current per-file deletion solutions tend to be limited to a segment of the operating system’s storage data path or specific to certain file systems or storage media.
This paper introduces TrueErase, a holistic secure-deletion framework. Through design, implementation, verification, and evaluation, we show that it is possible to build a legacy-compatible full-storage-data-path framework that performs per-file secure deletion, works with common file systems and solid-state storage, while handling common system failures. In addition, this framework can serve as a building block for encryption- and tainting-based secure-deletion systems.
