Cryptosystems based on space-discretization of chaotic maps

摘要

Many kinds of chaotic cryptosystems have been proposed so far. However, most of them do not have enough security. In the present paper, a new kind of chaotic cryptosystem is proposed. The cryptosystem is based on a discretization of the skew tent map. The security is also investigated based on dynamical characteristics. Dynamical system theory is helpful for designing chaotic cryptosystems.
