Abstract
This paper presents a effcient proposal for iterating hash functions
to prevent the main of generic attacks such as Multicollisions Attack,Second
Preimage Attack and Herding Attack.Based on this proposal,it’s possible that a
secure hash function can be built with iterating compression functions .
The proposal mainly contains a method called ” Shifting Whole Message”,it
regroups the cascaded messages to be new blocks and makes the known results
of the pre-computed blocks noneffective
