Provable Security Against a Differential Attack

open access: yesDAIMI Report Series, 1994
The purpose of this paper is to show that there exist DES-like iterated ciphers, which are provably resistant against differential attacks. The main result on the security of a DES-like cipher with independent round keys is Theorem 1, which gives an upper bound to the probability of <em>s</em>-round differentials, as defined in <em> ...

Improvement on the XTP public key cryptosystem and communication protocol of provable security

open access: yesTongxin xuebao, 2007
A new trace function was proposed,the XTP public key cryptosystem based on the 3-rd order LFSR se-quence(the so-called XTR3 system) was extended to the XTR4 system based on the 4-th order LFSR sequence.XTR4 key was shorter in length than that of the XTR3
