In an effort to design a MAC scheme that is built using block cipher components and runs faster than the modes of operation for message authentication, the researchers have proposed a generic MAC construction ALRED and a concrete ALRED instance Pelican. The Pelican MAC uses four rounds of AES as a building block to compute the authentication tag in a CBC-like manner. It is about 2.5 times faster than a CBC-MAC with AES, but it is not proven secure.
