摘要

The authors propose to design frequency-encoded Tristate serial data secured encryption technique depending on an additional bit sent along with the control data which determines this type of encryption. In this paper, Mach–Zehnder Interferometer-based Semiconductor Optical Amplifiers (MZI-SOAs) have been employed in this technique as a frequency converter. This technique also provides inline optical data cryptography in the physical layer which is advantageous in the fields of real-time operations, long-haul communication techniques and optical fiber networks. The encryption is being processed in real-time and operates in the THz frequency range. The operation of the proposed scheme is also being verified by the Matlab Simulink simulation experiment.
