Abstract: | In this note we revisit the rate-1 blockcipher based hash functions as first studied by Preneel, Govaerts and Vandewalle (Crypto'93) and later extensively analysed by Black, Rogaway and Shrimpton (Crypto'02). We analyze a further generalization where any pre- and postprocessing is considered. By introducing a new tweak to earlier proof methods, we obtain a simpler proof that is both more general and more tight than existing results. As added benefit, this also leads to a clearer understanding of the current classification of rate-1 blockcipher based schemes as introduced by Preneel et al. and refined by Black et al. |
