Information Leakage of a Kind of Block Cipher Structure

Abstract:

The block cipher New Structure II was designed at eprint 2011, it could be treated as a generalized Feistel structure. By checking the property of the linear permutation, we find a full round differential in New Structure II with probability 1. Since this differential can not distinguish the correct unknown key from the wrong keys, we fail in launching a key-recovery attack on this structure. However, we may guess 1/4 part of the plaintext without calculating the key. And we notice this weakness may cause insecurity in some special environments.
