In this letter we demonstrate that the improvement of cryptosystem based on iterating chaotic map proposed by Yong in 2007 are weak and this cryptosystem can be easily broken using chosen plaintext attack. Then, we give novel improvements to the proposed chaotic cryptosystem. We choose image as plaintext, some experimental tests like sensitivity on initial condition and correlation between two adjacent...
Chaos-based communication can be applied advantageously only if the property of chaotic systems is suitably exploited. Chaos communication has been studied for only a little more than a decade while traditional communication schemes have been developed for nearly a century. The hope was (and still is) that for some application chaotic communication will prove to be better than traditional communication...
