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. Designed by Tadayoshi Kohno, John Viega and Doug Whiting, NIST is currently considering CWC mode for standardization. It combines the use of CTR mode for encryption with an efficient polynomial Carter–Wegman MAC.
