Horus: Fine-Grained Encryption-Based Security for High Performance Petascale Storage

Data used in High-Performance Computing (HPC) applications is often sensitive, necessitating protection against both physical compromise of the storage media and "Rogue" computation nodes. Existing approaches to security may require trusting storage nodes and are vulnerable to a single computation node gathering keys that can unlock all of the data used in the entire computation. The authors' approach, Horus, encrypts petabyte-scale files using a keyed hash tree to generate different keys for each region of the file, supporting much finer-grained security.
