We propose a class of chaotic system a so-called Chiang type chaotic system. First the chaotic system is represented by T-S fuzzy models. Then based on this type of chaotic system, a new cryptosystem is developed. The advantage of this cryptosystem is a significant increase in the plaintext to chaotic signal ratio which is beneficial in coping with channel noise. In addition, this cryptosystem allows increase of the power of plaintext and maintains high security.
