The block cipher VGF2 was designed at Inscrypt 2009. It was based on a new variant of generalized Feistel structure. By checking the property of the linear permutation, we find a full round differential in VGF2 with probability 1. Since this differential cannot distinguish the correct unknown key from the wrong keys, we fail in launching a key-recovery attack on this structure. However, we may guess half part of the plaintext without calculating the key. And we notice that this weakness maydoi:10.1155/2013/962342 fatcat:lkiewvvabncxrf3uwmq3g7ivqy
