ZOCB and ZOTR: Tweakable Blockcipher Modes for Authenticated Encryption with Full Absorption
ZOCB ZOTR Authenticated encryption Associated data
2019/6/3
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,...

In this paper, we define and analyze a new blockcipher mode of operation for
encryption, CENC, which stands for Cipher-based ENCryption. CENC has the following
advantages: (1) beyond the birthday bo...
