Abstract

This paper proposes the use of a nonlinear ring resonator to form the secure information for telephone conversation, especially, for mobile telephone networks. Three techniques of the security code generation are proposed in this work, which these techniques the telephone conversation can be kept in secret, i.e., the telephone message security is performed. The techniques called chaotic encryption and decryption, quantum cryptography and quantum chaos are implemented into the telephone system using the fiber/micro ring device via the optical wireless communication link. The potential of using the three proposed signal processing techniques incorporating the fiber optic/integrated optic devices in the mobile telephone hand set and network is described.
