Block-Level Security for Network-Attached Disks
Overview This paper proposes a practical and efficient method for adding security to Network-Attached Disks (NADs). In contrast to previous work, the design requires no changes to the data layout on disk, minimal changes to existing NADs, and only small changes to the standard protocol for accessing remote block-based devices. Thus, existing NAD file systems and storage-management software could incorporate the scheme very easily. The design enforces security using the well-known idea of self-describing capabilities, with two novel features that limit the need for memory on secure NADs: a scheme to manage revocations based on capability groups, and a replay-detection method using Bloom filters.
