In this talk, chaos-based cryptography is discussed from a point of view which I believe is closer to the spirit of both cryptography and chaos theory than the way the subject has been treated recently by many researchers. I propose a public-key encryption algorithm based on chaotic maps, which it seems to be secure, it is practical, and can be used for both encryption and digital signature. Software implementation and properties of the algorithm are discussed in detail when Chebyshev maps are employed. Public-key encryption schemes based on other classes of chaotic maps are also discussed.
