Objective: To present a new method for generating a recursive sequence in image encryption using the genetic algorithm. Methods: In order to accomplish these goals in this study, the coefficients of the recurrence relation are calculated by the genetic algorithm taking into account a generic form for the recurrence relation and the definition of a proper fitness function, so that the resulting sequence has the optimal efficiency for image encryption. Findings: With the implementation of the algorithm, the results obtained from values UACI, NPCR, MAE, the fitness function, and Correlation, it is seen that the proposed method in this paper is more effective than old methods. Application: In order to achieve these results, at each stage of the implementation of the genetic algorithm, using a chromosome gene, a 2D time sequence is generated, and this sequence is used to scramble the image.
