    In recent years, the sharing of information has become more prevalent than the past due to the rapid development of Internet and mobile communication technologies. However, in open networks, there is a potential risk of making sensitive information, such as military orders vulnerable to unauthorized interceptions. The development of robust cryptographic schemes is thus essential to the provision of information security. During the last decade an interesting relationship between cryptography and chaos theory has been developed. Consequently, several chaos-based cryptosystems have been put forward. In this context, this paper presents a novel text message encryption scheme which is based on a Chaotic Random Number Generator. This system is realized by the Arduino, an open-source physical computing platform based on a simple microcontroller board. As a chaotic system, the well-known Chua system is chosen, due to its rich dynamical behavior. The quality of the produced random number sequences is tested by the FIPS-140-2 statistical suite. The satisfactory results from the use of the a forementioned statistical tests, in regard to other previous works, confirm the usefulness of the proposed text encryption scheme.
