Overview of Information Security Using Genetic Algorithm and Chaos

Security, integrity, nonrepudiation, confidentiality, and authentication services are the most important factors in information security. Genetic algorithms (GAs) are a class of optimization algorithms. Many problems can be solved using genetic algorithms through modeling a simplified version of genetic processes. The application of a genetic algorithm to the field of cryptology is unique. Few works exist on this topic. In this article, an attempt has been made to give an overview of genetic algorithm-based cryptography and to propose a new approach to GA with pseudorandom sequence to encrypt data stream. The feature of such an approach includes high data security and high feasibility for easy integration with commercial multimedia transmission applications. The experimental results of the proposed technique confirm that high throughput rate needed for real time data protection is achieved.
