Abstract
The usage of non-volatile memory (NVM) storage devices is rapidly increasing in consumer and enterprise systems, providing high performance and low energy consumption compared to hard disk drives. Lately it is observed that NVM storage devices are widely used in cloud computing as well. However, existing disk encryption methods are designed for hard disk devices and an efficient block cipher mode of operation for NVM storage devices has not yet been studied in detail. In this work we have analyzed and evaluated performance of CBC, CTR and XTS-AES block cipher modes for whole disk encryption solutions and found that CTR and XTS-AES modes outperform CBC mode under the same scenarios.
