Summary:
We have developed a chaos-based cryptographic method using the augmented Lorenz equations. In our method, the secret key is given as an N-dimensional real diagonal matrix that specifies the augmented Lorenz equations, being assumed to be shared between legitimate users using a quantum key distribution. We apply our method to speech encryption and evaluate its security on the basis of the degree of visible determinism in chaotic sequences as pseudorandom numbers generated by the augmented Lorenz equations.
