A Symmetric Image Encryption Scheme Based on Composite Discrete Chaotic System
Yang Hua · 2006
In this paper, a symmetric image encryption scheme based on composite discrete chaotic system is presented. In the proposed scheme, when the chaos sequence is generated, the iteration times are hidden to avoid cryptanalysis based on symbolic dynamic. Theoretical analysis and simulated experiment show that, the scheme has excellent performances against attacks, in particular statistical attack, differential attack and chosen plain image attack.
