This paper presents an improvement to an existing method used in security data transmission based on discrete time hyperchaotic cryptography. The technique is implemented for a R¨ossler hyperchaotic generator. The improvement consists in modifying the structure of the existing generator in order to increase the robustness of the new cryptosystem with respect to known plain text attack, particularly the “identification technique”.
