ZOCB and ZOTR: Tweakable Blockcipher Modes for Authenticated Encryption with Full Absorption

We define ZOCB and ZOTR for nonce-based authenticated encryption with associated data, and analyze their provable security. These schemes use a tweakable blockcipher (TBC) as the underlying primitive, and fully utilize its input to process a plaintext and associated data (AD). This property is comm...
