CWC mode
In cryptography, CWC Mode (Carter–Wegman + CTR mode) is an AEAD block cipher mode of operation that provides both encryption and built-in message integrity, similar to CCM and OCB modes. It combines the use of CTR mode for encryption with an efficient polynomial Carter–Wegman MAC and is designed by Tadayoshi Kohno, John Viega and Doug Whiting. NIST  previously considered CWC mode for standardization, but opted for the similar GCM mode instead.
