A New Proposal Against the Main of Generic Attacks

Xigen.Yao

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 .

Category / Keywords: hash function ,iterating ,shift ,regrouped block,pre-computed
