Title
The preimage security of double-block-length compression functions
Abstract
We present new techniques for deriving preimage resistance bounds for block cipher based double-block-length, double-call hash functions. We give improved bounds on the preimage security of the three "classical" double-block-length, double-call, block cipher-based compression functions, these being Abreast-DM, Tandem-DM and Hirose's scheme. For Hirose's scheme, we show that an adversary must make at least 22n−5 block cipher queries to achieve chance 0.5 of inverting a randomly chosen point in the range. For Abreast-DM and Tandem-DM we show that at least 22n−10 queries are necessary. These bounds improve upon the previous best bounds of Ω(2n) queries, and are optimal up to a constant factor since the compression functions in question have range of size 22n.
