Chaos − based cryptography. A possible solution for information security

Abstract

The development of new information security systems based on chaos theory represents a new research field in the 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 of the chaos-based cryptography stage. The essence of the theoretical and practical efforts which are done in this new field is represented by the idea that a chaos-based cryptosystem is capable to have similar performances to the classic methods based on computational techniques. We show that some of these performances are obtained using several well-known chaotic ciphers.
