Security Validation of Continuous-Time Chaotic Communication Systems by Error Function Attack

This paper proposes a statistical testing for the security analysis of a secure communication scheme based on continuous-time chaotic systems. First, we define an instantaneous EFA function that does not include the average operation. Secondly, we propose a statistical testing for cryptanalysis, which calculates a kurtosis and a skewness of the EFA function obtained by random trial keys. Finally, simulation results for the proposed security test are presented
