In this paper, we present new distinguishers of the MAC construction \textsc{Alred} and its specific instance \textsc{Alpha}-MAC based on AES, which is proposed by Daemen and Rijmen in 2005. For the \textsc{Alred} construction, we describe a general distinguishing attack which leads to a forgery attack directly. The complexity is $2^{64.5}$ chosen messages and $2^{64.5}$ queries with success probability 0.63. We also use a two-round collision differential path for \textsc{Alpha}-MAC, to...
