Abstract
The output values of chaotic functions look highly unpredictable and random-like. These features are in accord with the requirements for secure cryptosystems. For this reason, many kinds of cryptosystems using chaotic functions have been proposed so far. However, most of those algorithms are not applicable for light cryptosystems because they need a high level of computing ability. In this paper, we propose a new light chaotic cryptosystems which are suitable for the systems with a low level of computing ability. From the simulations, we show the performance of proposed cryptosystems on computational complexity and security level.
