Cryptanalysis and Improvement of a Block Cipher Based on Multiple Chaotic Systems
Wang and Yu proposed a block cipher scheme based on dynamic sequences generated by multiple chaotic systems, which overcomes the problem of periodical degradation on random sequences due to computational precision. Their scheme has a feature that a plaintext is encrypted by a keystream created from several one-dimensional chaotic maps. However, this feature results in some weaknesses of the enc...
متن کاملA Stream Cipher Based on Chaotic Permutations
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field. We will show that this system can operate in both synchronized and self-synchronized modes. More specifically, we show that in the self-synchronized mode the stream cipher has a receiver operating as an unknown input o...
متن کاملCryptanalysis of a Chaotic Neural Network based Chaotic Cipher
Recently a Triple key encryption method based on logistic map was proposed. The present paper analysis the security of the proposed encryption method and points out that it can be easily broken by one pair of known/chosen plain-text attack which is supported by mathematical proof and experimental result. In addition, some other security defects are also reported.
متن کاملCryptanalysis and improvement on a block cryptosystem based on iteration a chaotic map
Recently, a novel block encryption system has been proposed as an improved version of the chaotic cryptographic method based on iterating a chaotic map. In this Letter, a flaw of this cryptosystem is pointed out and a chosen plaintext attack is presented. Furthermore, a remedial improvement is suggested, which avoids the flaw while keeping all the merits of the original cryptosystem. © 2006 Els...
متن کاملNovel Impossible Differential Cryptanalysis of Zorro Block Cipher
Impossible difference attack is a powerful tool for evaluating the security of block ciphers based on finding a differential characteristic with the probability of exactly zero. The linear layer diffusion rate of a cipher plays a fundamental role in the security of the algorithm against the impossible difference attack. In this paper, we show an efficient method, which is independent of the qua...
