This paper concisely summarizes the XTS block encryption mode for storage sector-based encryption applications and clarifies its limitations. In particular, we aim to provide a unified basis for constructive discussions about the newly introduced key scope change to the IEEE 1619 standard. We also reflect on wide modes that could replace XTS in the future.
