We present Weimar-DM, a double length compression function using two calls to a block cipher with 2n-bit key and n-bit block size to compress a 3n-bit string to a 2n-bit one. For Weimar-DM, we show that for n=128, no adversary asking less than 2n−1.77=2126.23 queries can find a collision with probability greater than 1/2. This is the highest collision security bound ever shown for such a compression function. Even more important, our security analysis is much simpler than that for comparable functions as, e.g., Tandem-DM, Abreast-DM or Hirose-DM. We also give a preimage security analysis of Weimar-DM showing a near-optimal bound of 22n−5=2251 queries. Our security bounds are asymptotically optimal.
