The Pelican MAC Function

Joan Daemen and Vincent Rijmen

Abstract: At FSE 2005 we presented a new MAC Construction called Alred and a Specific Instance Alpha-MAC. In the presentation we announced a variant of Alpha-MAC under the (working) name Beta-MAC, that can be seen as an optimized version of Alpha-MAC.

We have renamed Beta-MAC to Pelican and present its design in this paper. Pelican is based on Rijndael and a factor 2.5 more efficient than CBC-MAC with Rijndael, while providing a comparable claimed security level.
