Abstract :
In this paper, we have implemented a secure communication platform based on a new stream cipher called Gemstone which stems from coupled map lattices (CML), a nonlinear system of coupled chaotic maps. On the platform, we have realized duplex text, image and voice transmission. We have also analyzed the randomness of the keystream generated by the platform based on the statistical tests suggested by the National Institute of Standards and Technology (NIST). The test results are compared with other four stream ciphers´. Moreover, a series of experiments of duplex text, image and voice transmissions were made through university local network. Both the statistical test and the transmission experiments have shown that the platform is highly secure with fast encryption speed, which confirms that the Gemstone platform is promising for cryptographic applications.
