The concern about security and integrity of confidential messages has always been target of study. One of the most used techniques for this purpose is the encryption, which consists of hiding a message, making it incomprehensible, ensuring that only the sender and the addressee have access to its original content. In this process, the algorithm applies a key on the message, which aims to hide the message to send it or reveal it when it arrives at destination. In this paper we present a solution on this domain based on the use of metaheuristics for the design of unidimensional chaotic cellular automata used as a key generator for stream cipher algorithms.
