Image Encryption Algorithm Cryptanalysis Based on One-dimensional Discrete Chaotic Map
Zhigang Chen · Jisuanji gongcheng · 2006
This paper points out that the substitute encryption algorithm proposed in reference1 cannot resist known-plaintext attack.The analyses show that the key of this cipher can be found with very few known plaintext-cipher pairs;and the permutation algorithm is only provided with very small key space.So an attack scheme is proposed,and the example of the attack scheme successfully brokes the encryption algorithm.A proposal for improvement algorithm is proposed,too.
