The Collision Security of MDC-4

  title={The Collision Security of MDC-4},
  author={Ewan Fleischmann and Christian Forler and Stefan Lucks},
There are four somewhat classical double length block cipher based compression functions known: MDC-2, MDC-4, Abreast-DM, and Tandem-DM. They all have been developed over 20 years ago. In recent years, cryptographic research has put a focus on block cipher based hashing and found collision security results for three of them (MDC-2, Abreast-DM, Tandem-DM). In this paper, we addMDC-4, which is part of the IBM CLiC cryptographic module, to that list by showing that – ’instantiated’ using an ideal… CONTINUE READING
