XTS is the standardized mode defined in IEEE 1619 (Standard for Cryptographic Protection of Data on Block-Oriented Storage Devices).
XTS-AES-128 performance is nearly identical to standard AES-128-ECB in terms of cycles per byte, as the primary computational cost is the AES encryption of the data itself. encryption method xts aes 128
XTS includes to handle data units whose size is not a multiple of the AES block size (128 bits). This avoids padding, which is critical for disk encryption where the data length must remain exactly the same as the original. XTS is the standardized mode defined in IEEE
XTS-AES-128 represents the optimal balance of security, performance, and functionality for data-at-rest encryption. By solving the issues of padding overhead and deterministic ciphertext patterns via the XEX tweak mechanism, it provides a robust defense against forensic analysis of storage media. This avoids padding, which is critical for disk
If the final data block is partial (less than 16 bytes), XTS employs ciphertext stealing.
