Chaos-based Cryptography. a Possible Solution for Information Security

The development of the new information security systems based on chaos theory represents a new research field in communication and information technology domain. Cryptography is a permanent field of interest at all times. At present secret communication plays an increasing role in many fields of common life, like banking, industry, and telecommunication. In this paper we present some aspects regarding the chaosbased cryptography stage. The essence of the theoretical and practical efforts which are done in this new field is represented by the idea that chaos-based cryptosystem is capable to have similar performances regarding the classic methods based on computational techniques. We show that some of these performances are obtained using several well-known chaotic ciphers.
