<p>In <a href="Cryptography" title="Cryptography">cryptography</a>, <b>CWC Mode</b> (Carter–Wegman + <a href="Block_cipher_modes_of_operation" class="mw-redirect" title="Block cipher modes of operation">CTR</a> mode) is an <a href="AEAD_block_cipher_modes_of_operation" class="mw-redirect" title="AEAD block cipher modes of operation">AEAD block cipher mode of operation</a> that provides both encryption and built-in message integrity, similar to CCM and OCB modes. It combines the use of CTR mode with a 128-bit block cipher for encryption with an efficient polynomial Carter–Wegman MAC with a tag length of at most 128 bits and is designed by <a href="Tadayoshi_Kohno" title="Tadayoshi Kohno">Tadayoshi Kohno</a>, <a href="John_Viega" title="John Viega">John Viega</a> and Doug Whiting.<sup id="cite_ref-spec_1-0" class="reference"><a href="#cite_note-spec-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
