Distinguishing Attack on the Secret-Prefix MAC Based on the 39-Step SHA-256ix MAC with the length prepended to the message before hashing and it’s a more secure version of the secret-prefix MAC. In [19], Wang .t al. give the first distinguishing attack on HMAC/NMAC-MD5 without the related key, then they improve the techniques to give a distinguishing attack on the LPMAC ba
