Abstract:

Nowadays, communications networks becomes an essential tool for exchange information. This fact allows having robust systems that ensures secure transfers against arbitrary intrusion. In literature, we encounter various encryption schemes that meet this requirement. In this paper, we interest to the chaos cipher map that achieved image encryption and its resistance against attacks based on genetic algorithm, an efficiency bio-inspired heuristic that used as powerful tool for resolution of complex combinatory problems. The skill of the approach is the use of such heuristic, and for a first time, in attack of image encryption schemes. We show its effectiveness by reporting results of some preliminary experiments, including a comparison with brute force attack.
