Summary:
A chaotic map has sensitivity to a change in initial conditions and parameters, and a long-term forecast becomes impossible by iterations of a chaotic map. These features look similar to the properties of the cryptology. For that reason, it is effective to use chaotic maps for cryptosystems. In this research, we propose a cryptosystem using iterations of a chaotic map. This cryptosystem uses expansion map for encryption and decryption. This cryptosystem is a symmetrickey cryptography that has a public key. We investigate the vulnerability of this cryptosystem.
