Is chaos-based encryption a rigorous discipline? And why there are objections to it within the cryptography community? And why are many of its cryptosystems weak? And does it has a promising future? And is there any example of secure cryptographic systems based on chaos?
Also, some people differentiate between the legitimacy of analog vs digital chaos-based cryptography, is this right?
The most important question: given the criticism, why do scientific journals still publish these systems?
