	abstract	 = {It has become important to reliably protect stored digital data, both against becoming inaccessible as well as becoming available to third parties. Using a file system which guarantees data integrity protects against data losses, disk encryption protects against data breaches. Encryption is still thought to incur a large performance penalty when accessing the data. This thesis evaluates different approaches to data encryption using low-power hardware and open-source software, with a focus on the advanced file system OpenZFS, which features excellent protection against data loss but does not include encryption. It is shown that encryption using LUKS beneath ZFS is a viable method of gaining data protection, especially when using hardwareaccelerated encryption algorithms. Using a low-power server CPU with native AES instructions, ZFS as the file system and LUKS for encryption of the block device permits ensuring data integrity and protection at a low cost.},
