The Road from Panama to Keccak via RadioGatún



In this presentation, we explain the design choices of Panama [1] and RadioGatun [2], which lead to Keccak [3]. After a brief recall of Panama, RadioGatun and the trail backtracking cost, we focus on three important aspects. First, we explain the role of the belt in the light of differential trails. Second, we discuss the relative advantages of a block mode hash function compared to a stream mode one. Finally, we point out why Panama and RadioGatun are not sponge functions and why their design philosophy differs from that of Keccak. [1] J. Daemen and C. S. K. Clapp, FSE 1998 [2] G.
