Abstract
In this paper, we present a semi-free-start collision attack on the compression function for all Twister variants with negligible complexity. We show how this compression function attack can be extended to construct collisions for Twister-512 slightly faster than brute force search. Furthermore, we present a second-preimage and preimage attack for Twister-512 with complexity of about 2384 and 2456 compression function evaluations, respectively. © 2009 Springer Berlin Heidelberg.
