DES Collisions Revisited

Journal Contribution - Journal Article

We revisit the problem of finding key collisions for the DES block cipher, twenty two years after Quisquater and Delescaille demonstrated the first DES collisions. We use the same distinguished points method, but in contrast to their work, our aim is to find a large number of collisions. A simple theoretical model to predict the number of collisions found with a given computational effort is developed, and experimental results are given to validate this model. © 2012 Springer-Verlag Berlin Heidelberg.
