NV-eCryptfs: Accelerating Enterprise-level Cryptographic File System with Non-Volatile Memory |
Abstract | ||
|---|---|---|
The development of cloud computing and big data results in a large amount of data transmitting and storing. In order to protect sensitive data from leakage and unauthorized access, many cryptographic file systems are proposed to transparently encrypt file contents before storing them on storage devices, such as eCryptfs. However, the time-consuming encryption operations cause serious performance degradation. We found that compared with non-crypto file system EXT4, the performance slowdown could be up to 58.53% and 86.89% respectively for read and write with eCryptfs. Although prior work has proposed techniques to improve the efficiency of cryptographic file system through computation acceleration, no solution focused on the inefficiency working flow, which is demonstrated to be a major factor affecting system performance. |
